+This is a list of "frequently" asked questions.
+
+1.1) What can I do when reprepro complains about a missing .orig.tar.gz?
+1.2) Why does it refuse a file when one in another suite has the same name?
+1.4) The key to sign my Release files needs a passphrase, what to do?
+1.5) How do I change how files are downloaded.
+1.6) How to omit packages missing files when updating.
+2.1) Does reprepro support to generate Release.gpg files?
+2.2) Does reprepro support tildes ('~') in versions?
+2.3) Does reprepro support generation of Contents-<arch>.gz files?
+3.1) Can I have two versions of a package in the same distribution?
+3.2) Can reprepro pass through a server-supplied Release.gpg?
+9) Feature ... is missing, can you add it?
+
+
+1.1) What can I do when reprepro complains about a missing .orig.tar.gz?
+------------------------------------------------------------------------
+When 'include'ing a .changes file reprepro by default only adds files
+referenced in the .changes file into the pool/-hierarchy and does not
+search for files referenced in a .dsc file and thus fails if this .orig.tar.gz
+is not already in the pool.
+You are facing the choice:
+- copy the .orig.tar.gz by hand into the appropriate place within pool/
+ and try again. reprepro will find it there when you try it the next time
+ and add it to its database.
+- use --ignore=missingfile to tell reprepro to search for such files
+ in the directory the .changes file resides in.
+- modify the .changes file by hand to reference the .orig.tar.gz
+- use changestool (comes with reprepro since version 1.3.0) to
+ list the file. ("changestool <.changesfile> includeallsources")
+- use dpkg-buildpackage -sa the next time you build a package so that
+ it calls dpkg-genchanges with -sa which then always lists .orig.tar.gz
+ and not only if it ends in -0 or -1.
+
+1.2) Why does it refuse a file when one in another suite has the same name?
+----------------------------------------------------------------------------
+Reprepro uses Debian's way to organize the pool hierarchy, which means
+that the directory and name a file is saved under is only determined by
+its sourcename, its name and its version and especially not by the
+distribution it belongs to. (This is the intent of having a pool directory,
+so that if two distributions have the same version, the disk space is only
+used once). This means that if different versions of a packaged having the
+same version string are put in the same reprepro repository (even if put
+into different distributions within that), reprepro will refuse to do so.
+(Unless you have a md5sum collision, in which case it will put the one and
+just replace the second with the first).
+
+The only way to work around, is too put the different distributions into
+different repositories. But in general it is really worth the effort to
+get the versioning right instead: Having multiple packages with the same
+version make it hard to track down problems, because it is easy to mix
+them up. Also up/downgrading a host from one distribution to the other
+will not change the package but just keep the old (as they are the
+same version, so they have to be the same, apt and dpkg will think).
+
+How to deal with this without separating repositories depends on how
+you reached this situation:
+
+- in the past Debian's stable and stable-security buildds sometimes both
+ built a package and for some architectures the one version entered
+ security.debian.org and the other ftp.debian.org with the next
+ point release. (This should be fixed now. And it is always considered
+ a bug, so if you hit this, please report it). If you mirror such
+ a situation, just update one of the distributions and manually
+ include the package into the other distribution. As the versions
+ are the same, reprepro will keep with this and not try to download
+ the other version, err other same version, err ...
+- backports (i.e. packages rebuild for older distributions)
+ Common practise is to append the version with reducing ~,
+ i.e. 1.0-1 becomes 1.0-1~bpo.7, or 3.0 becomes 3.0~sarge.
+ (This makes sure that if a host is updated the backport is
+ replaced by the real package).
+ If backporting to multiple distributions you get bonus points
+ for making sure newer distributions have higher version numbers.
+ (To make sure which version is considered newer by dpkg use
+ dpkg's --compare-versions action).
+- a package built for multiple distributions
+ is equivalent to the backports case
+- locally modified packages that should be replace by newer official
+ versions: append something like "a0myname". If it should be
+ replaced by security updates of the official package, make sure (using
+ dpkg's --compare-versions) that a security update would have
+ a higher version.
+- locally modified packages that should not be replaced by newer
+ official versions: prefix the version with "99:" and perhaps appending
+ it with something like "-myname". (appending only makes it easier to
+ distinguish, as some tools do not show epochs).
+
+1.4) The key to sign my Release files needs a passphrase, what to do?
+---------------------------------------------------------------------
+Please take a look at gpg-agent.
+You can also use the --ask-passphrase option, but please note this is quite insecure.
+
+1.5) How do I change how files are downloaded.
+----------------------------------------------
+reprepro just calls apt's methods for file retrieval.
+You can give them options in conf/updates like
+Config: Acquire::Http::Proxy=http://proxy.yours.org:8080
+or replace them with other programs speaking the same
+interface.
+
+1.6) How to omit packages missing files when updating.
+------------------------------------------------------
+reprepro does not like broken upstream repositories and just splits out
+errors and does not process the rest. (Implementing simply a ignore for
+that is not that easy, as I would have special case holding an old version
+in that case when unavailable packages should be deleted, and make some
+costly information-pushing between layers (after all, each file can belong
+to multiple packages and packages can have more than one file, so keeping
+track which package should get a mark that files where missing needs a
+n-to-n relation that should never be uses expect the case where such a
+error happens)).
+What you can do when a upstream repository you update from misses a file:
+- try once with a different mirror not missing those files. You can either
+ change the mirror to use once and change it back afterwards. Or if both
+ mirrors have the same inner directory structure (they usually have) and
+ are accessible via the same method (like both http or both ftp) you can
+ also use the Fallback: option in conf/updates to tell reprepro to get
+ missing files from the other Mirror. This an even be used for things not
+ being a mirror of the same thing, but only having some files at the same
+ place. For example to work around etch r1 listing many older kernel
+ packages but no longer having the needed files, a line
+ Fallback: http://snapshot.debian.net/archive/2007/04/02/debian/
+ can help. (But make sure to look at the run and remove this line
+ once reprepro downloaded the missing files. With this line active and
+ the primary mirror you list in Method: unreachable, reprepro will also
+ download index files from snapshot and make your repository a copy of
+ unstable from 2007-04-02 instead of an updated etch version.)
+- get the file elsewhere (with the correct md5sum), place it in the
+ appropriate place in the pool/ hierarchy and do the update. Reprepro will
+ see the file is already there, add it to its database and just continue
+ with the update.
+- tell reprepro to exclude this package
+* There are multiple ways to do so. Easiest is adding something like
+ FilterFormula: package (!= xen-shell)
+ or
+ FilterFormula: package (!= xen-shell) | version (!=1.0-2) | !files
+ to your rule in conf/updates. ( the "| ! files" tells it to only
+ omit the source package xen-shell, as source packages have a files
+ field. Make sure the package in question does not require you to
+ make the source available or you are not making your repository
+ accessible to others).
+* Another way is adding something like
+ FilterList: install excludefile
+ and adding a file conf/excludefile with content
+ xen-shell deinstall
+ (the install will tell it to install what is not listed in the file,
+ the deinstall on xen-shell will tell it to not install that package)
+* Finally you can also supply a ListHook: with a script copying
+ its first argument to the second argument, removing all occurrences
+ of the package you do not want (take a look intro the dctrl-tool
+ package for tools helping you with this).
+- the worst solution is to just propagate the problem further, by just
+ telling reprepro the file is there with the correct md5sum while it
+ is not. (Via the _addmd5sums command of reprepro). Unless you
+ run checkpool reprepro will not notice what you have done and will
+ not even try to download that file once it becomes available. So
+ don't do this.
+
+2.1) Does reprepro support to generate Release.gpg files?
+---------------------------------------------------------
+Yes, add a SignWith in the suite's definition in conf/distributions.
+(and take a look what the man page says about SignWith)
+
+2.2) Does reprepro support tildes ('~') in versions?
+----------------------------------------------------
+Yes, but in .changes files only since version 0.5.
+(You can work around this in older versions by using includedeb and
+ includedsc on the .deb and .dsc files within the .changes file, though)
+
+2.3) Does reprepro support generation of Contents-<arch>.gz files?
+------------------------------------------------------------------
+Yes, since version 1.1.0 (well, actually since 0.8.2 but a bug
+caused the generated files to not be up to date unless manually
+exporting the distributions in question).
+Look for "Contents" in the man page.
+
+3.1) Can I have two versions of a package in the same distribution?
+-------------------------------------------------------------------
+Sorry, this is not possible right now, as reprepro heavily optimizes
+at only having one version of a package in a suite-type-component-architecture
+quadruple.
+You can have different versions in different architectures and/or components
+within the same suite. (Even different versions of a architecture all package
+in different architectures of the same suite). But within the same
+architecture and the same component of a distribution it is not possible.
+
+3.2) Can reprepro pass through a server-supplied Release.gpg?
+-------------------------------------------------------------------
+No.
+The reason for this is that the Release file will be different,
+so a Release.gpg would not match.
+The reason that the Release file looks differently is that reprepro
+mirrors packages. While it can create a distribution with the same
+packages as a distribution it mirrors. It will decide on its own where
+to put the files, so their Filename: or Directory: might differ. It may
+create a different set of compressions for the generated index files.
+It does not mirror Packages.diff directories (but only comes with helpers
+to create diffs between different states of the mirror). It does not mirror
+Contents files but creates them; and so on. So to be able to mirror
+distribution signatures almost all the functionality of reprepro would need
+to be duplicated (once supporting literal mirroring, once support local
+packages, partial mirroring, merging mirroring, pool condensing), thus I
+decided that this is better a task for another program. (Note that if
+you already have a local literal mirror, you can also use that as upstream
+for partial/merged/extended mirrored distributions of that. If you use
+the file:/// in Method: (as opposed to copy:///), reprepro will make
+hardlinks for files in pool/ if possible).
+
+9) Feature ... is missing, can you add it?
+------------------------------------------
+First, please take another look at the man page. My documentation is not
+very good, so it is easy to overlook some feature even when it is described
+already. If it is not there, just write me a mail (or better write a wishlist
+report to the Debian BTS, then it cannot get lost). Some things I add quite
+fast, other stuff takes a bit. Things incompatible with the current underlying
+infrastructures or past design decisions may never come, but if I have it on the
+TODO list of things to add, it help the code to develop in a direction that
+things like that might be possible in the future.

+.br
+will modify the \fBDistribution:\fP header inside \fIbloat.changes\fP
+to say \fIlocal\fP instead of what was there before.
+.P
+.B changestool \fIreprepro_1.2.0\-1.local_sparc.changes\fP includeallsources
+.br
+will modify the given file to also list \fB.orig.tar.gz\fP it does not list
+because you forgot to build it with
+.BR "dpkg\-buildpackage \-sa" .
+.P
+.B changestool \fIblafasel_1.0_abacus.changes\fP updatechecksums
+.br
+will update the md5sums to those of the files referenced by this file.
+(So one can do quick'n'dirty corrections to them before uploading to
+your private package repository)
+.P
+.B changestool \-\-create \fItest.changes\fP add \fIbla_1\-1.dsc bla_1\-1_abacus.deb\fP
+.br
+will add the specified files (format detected by filename,
+use \fBadddeb\fP or \fBadddsc\fP if you know it).
+If the file \fItest.changes\fP does not exist yet, a minimal one will be
+generated. Though that might be too minimal for most direct uses.
+
+.SH "GLOBAL OPTIONS"
+Options can be specified before the command. Each affects a different
+subset of commands and is ignored by other commands.
+.TP
+.B \-h \-\-help
+Displays a short list of options and commands with description.
+.TP
+.B \-o \-\-outputdir \fIdir\fP
+Not yet implemented.
+.TP
+.B \-s \-\-searchpath \fIpath\fP
+A colon-separated list of directories to search for files if they
+are not found in the directory of the .changes file.
+.TP
+.B \-\-create
+Flag for the commands starting with \fBadd\fP to create the \fB.changes\fP
+file if it does not yet exists.
+.TP
+.B \-\-create\-with\-all\-fields
+Flag for the commands starting with \fBadd\fP to create the \fB.changes\fP
+file if it does not yet exists.
+Unlike \fB\-\-create\fP, this creates more fields to make things like dupload
+happier.
+Currently that creates fake \fBUrgency\fP and \fBChanges\fP fields.
+.TP
+.B \-\-unlzma \fIcommand\fP
+External uncompressor used to uncompress lzma files to look
+into .diff.lzma, .tar.lzma or .tar.lzma within .debs.
+.TP
+.B \-\-unxz \fIcommand\fP
+External uncompressor used to uncompress xz files to look
+into .diff.xz, .tar.xz or .tar.xz within .debs.
+.TP
+.B \-\-lunzip \fIcommand\fP
+External uncompressor used to uncompress lzip files to look
+into .diff.lz, .tar.lz or .tar.lz within .debs.
+.TP
+.B \-\-bunzip2 \fIcommand\fP
+External uncompressor used to uncompress bz2 when compiled without
+libbz2.
+.SH COMMANDS
+.TP
+.BR verify
+Check for inconsistencies in the specified \fB.changes\fP file and the
+files referenced by it.
+.TP
+.BR updatechecksums " [ " \fIfilename\fP " ]"
+Update the checksum (md5sum and size) information within the specified
+\fB.changes\fP file and all \fB.dsc\fP files referenced by it.
+Without arguments, all files will be updated.
+To only update specific files, give their filename (without path) as
+arguments.
+.TP
+.BR setdistribution " [ " \fIdistributions\fP " ]"
+Change the \fBDistribution:\fP header to list the remaining arguments.
+.TP
+.BR includeallsources " [ " \fIfilename\fP " ]"
+List all files referenced by \fB.dsc\fP files mentioned in the \fB.changes\fP
+file in said file.
+Without arguments, all missing files will be included.
+To only include specific files, give their filename (without path) as
+arguments.
+
+Take a look at the description of \fB\-si\fP, \fB\-sa\fP and \fB\-sd\fP in
+the manpage of \fBdpkg\-genchanges\fP/\fBdpkg\-buildpackage\fP how to avoid
+to have to do this at all.
+
+Note that while \fBreprepro\fP will just ignore files listed in a \fB.changes\fP
+file when it already has the file with the same size and md5sum, \fBdak\fP
+might choke in that case.
+.TP
+.B adddeb \fIfilenames\fP
+Add the \fB.deb\fP and \fB.udeb\fP files specified by their filenames to
+the \fB.changes\fP file.
+Filenames without a slash will be searched

+and in the directories specified by the \fB\-\-searchpath\fP.
+.TP
+.B adddsc \fIfilenames\fP
+Add the \fB.dsc\fP files specified by their filenames to
+the \fB.changes\fP file.
+Filenames without a slash will be searched
+in the current directory,
+in the directory the changes file resides in
+and in the directories specified by the \fB\-\-searchpath\fP.
+.TP
+.B addrawfile \fIfilenames\fP
+Add the files specified by their filenames to
+the \fB.changes\fP file.
+Filenames without a slash will be searched
+in the current directory,
+in the directory the changes file resides in
+and in the directories specified by the \fB\-\-searchpath\fP.
+.TP
+.B add \fIfilenames\fP
+Behave like \fBadddsc\fP for filenames ending in \fB.dsc\fP,
+like \fBadddeb\fP for filenames ending in \fB.deb\fP or \fB.udeb\fP,
+and like \fBaddrawfile\fP for all other filenames
+.TP
+.B dumbremove \fIfilenames\fP
+Remove the specified files from the .changes file.
+No other fields (Architectures, Binaries, ...) are updated and
+no related files is removed.
+Just the given files (which must be specified without any \fB/\fP)
+are no longer listen in the .changes file (and only no longer in the
+changes file).

+The speciality of the example needing the ListHook and not

+<h2><a name="introduction">Introduction</a></h2>
+<h3>What reprepro does</h3>
+Reprepro is a tool to take care of a repository of Debian packages
+(<tt>.dsc</tt>,<tt>.deb</tt> and <tt>.udeb</tt>).
+It installs them to the proper places, generates indices of packages
+(<tt>Packages</tt> and <tt>Sources</tt> and their compressed variants)
+and of index files (<tt>Release</tt> and optionally <tt>Release.gpg</tt>),
+so tools like <tt>apt</tt> know what is available and where to get it from.
+It will keep track which file belongs to where and remove files no longer
+needed (unless told to not do so).
+It can also make (partial) partial mirrors of remote repositories,
+including merging multiple sources and
+automatically (if explicitly requested) removing packages no longer available
+in the source.
+And many other things (sometimes I fear it got a few features too much).
+<h3>What reprepro needs</h3>
+It needs some libraries (<tt>zlib</tt>, <tt>libgpgme</tt>, <tt>libdb</tt> (Version 3, 4.3 or 4.4)) and can be compiled with some more for additional features (<tt>libarchive</tt>,
+<tt>libbz2</tt>).
+Otherwise it only needs
+<tt>apt</tt>'s methods (only when downloading stuff),
+<tt>gpg</tt> (only when signing or checking signatures),
+and if compiled without <tt>libarchive</tt> it needs <tt>tar</tt> and <tt>ar</tt> installed.
+<br>
+If you tell reprepro to call scripts for you, you will of course need the interpreters for these scripts:
+The included example to generate pdiff files needs python. The example to extract
+changelogs needs dpkg-source.
+<h3>What this manual aims to do</h3>
+This manual aims to give some overview over the most important features,
+so people can use them and so that I do not implement something a second
+time because I forgot support is already there.
+For a full reference of all possible commands and config options take a
+look at the man page, as this manual might miss some of the more obscure
+options.
+<h2><a name="firststeps">First steps</a></h2>
+<h3>generate a repository with local packages</h3>
+<ul>
+<li>Choose a directory (or create it).</li>
+<li>Create a subdirectory called <tt>conf</tt> in there.</li>
+<li>In the <tt>conf/</tt> subdirectory create a file called <tt>distributions</tt>,
+with content like:
+<pre class="file">
+Codename: mystuff
+Components: main bad
+Architectures: sparc i386 source
+</pre>
+or with content like:
+<pre class="file">
+Codename: andy
+Suite: rusty
+Components: main bad
+Architectures: sparc i386 source
+Origin: myorg
+Version: 20.3
+Description: my first little repository
+</pre>
+(Multiple distributions are separated by empty lines, Origin, Version and Description
+are just copied to the generated Release files, more things controlling reprepro can
+appear which are described later).
+</li>
+<li>If your <tt>conf/distributions</tt> file contained a <tt>Suite:</tt> and you
+are too lazy to generate the symbolic links yourself, call:
+<pre class="shell">
+reprepro -b $YOURBASEDIR createsymlinks
+</pre>
+</li>
+<li>Include some package, like:
+<pre class="shell">
+reprepro -b $YOURBASEDIR include mystuff mypackage.changes
+</pre>
+or:
+<pre class="shell">
+reprepro -b $YOURBASEDIR includedeb mystuff mypackage.deb
+</pre>
+</li>
+<li>Take a look at the generated <tt>pool</tt> and <tt>dists</tt>
+directories. They contain everything needed to apt-get from.
+Tell apt to include it by adding the following to your <tt>sources.list</tt>:
+<pre class="file">
+deb file:///$YOURBASEDIR mystuff main bad
+</pre>
+or make it available via http or ftp and do the same <tt>http://</tt> or <tt>ftp://</tt> source.</li>
+</ul>
+<h3>mirroring packages from other repositories</h3>
+This example shows how to generate a mirror of a single architecture with
+all packages of etch plus security updates:
+<ul>
+<li>Choose a directory (or create it).</li>
+<li>Create a subdirectory called <tt>conf</tt> in there (if not already existent).</li>
+<li>In the <tt>conf/</tt> subdirectory create a file called <tt>distributions</tt>,
+with content like (or add to that file after an empty line):
+<pre class="file">
+Origin: Debian
+Label: Debian
+Suite: stable
+Version: 4.0
+Codename: etch
+Architectures: i386
+Components: main
+Description: Debian 4.0 etch + security updates
+Update: - debian security
+Log: logfile
+</pre>
+Actually only <tt>Codename</tt>, <tt>Components</tt>, <tt>Architecture</tt> and <tt>Update</tt> is needed, the rest is just information for clients.
+The <tt>Update</tt> line tells to delete everything no longer available (<tt>-</tt>),
+then add the <tt>debian</tt> and <tt>security</tt> rules, which still have to be defined:
+</li>
+<li>In the <tt>conf/</tt> subdirectory create a file called <tt>updates</tt>,
+with content like (or add to that file after an empty line:):
+or with content like:
+<pre class="file">
+Name: security
+Method: http://security.debian.org/debian-security
+Fallback: ftp://klecker.debian.org/debian-security
+Suite: */updates

+</pre>
+(If there are no Architecture, Components or UDebComponents, it will try all the distribution to update has. Fallback means a URL to try when the first cannot offer some file (Has to be the same method)).
+</li>
+<li>Tell reprepro to update:
+<pre class="shell">
+reprepro -b $YOURBASEDIR update etch
+</pre>
+</li>
+<li>Take a look at the generated <tt>pool</tt> and <tt>dists</tt>
+directories. They contain everything needed to apt-get from.
+Tell apt to include it by adding the following to your <tt>sources.list</tt>:
+<pre class="shell">
+deb file:///$YOURBASEDIR etch main
+</pre>
+or make it available via http or ftp.</li>
+</ul>
+<h2><a name="dirbasics">Repository basics</a></h2>
+An <tt>apt-get</tt>able repository of Debian packages consists of two parts:
+the index files describing what is available and where it is and the actual
+Debian binary (<tt class="suffix">.deb</tt>),
+installer binary (<tt class="suffix">.udeb</tt>),
+and source (<tt class="suffix">.dsc</tt> together with
+<tt class="suffix">.tar.gz</tt> or
+<tt class="suffix">.orig.tar.gz</tt> and
+<tt class="suffix">.diff.gz</tt>) packages.
+<br>
+While you do not know how these look like to use reprepro, it's always a good
+idea to know what you are creating.
+<h3>Index files</h3>
+All index files are in subdirectories of a directory called
+<tt class="dirname">dists</tt>. Apt is very decided what names those should
+have, including the name of <tt class="dirname">dists</tt>.
+Including all optional and extensional files, the hierarchy looks like this:
+
+<dl class="dir">
+<dt class="dir">dists</dt><dd>
+ <dl class="dir">
+ <dt class="dir">CODENAME</dt><dd>
+Each distribution has it's own subdirectory here, named by it's codename.
+ <dl class="dir">
+ <dt class="file">Release</dt><dd>
+This file describes what distribution this is and the checksums of
+all index files included.
+ </dd>
+ <dt class="file">Release.gpg</dt><dd>
+This is the optional detached gpg signature of the Release file.
+Take a look at the <a name="#signing">section about signing</a> for how to
+active this.
+ </dd>
+ <dt class="file">Contents-ARCHITECTURE.gz</dt><dd>
+This optional file lists all files and which packages they belong to.
+It's downloaded and used by tools like
+<a href="http://packages.debian.org/apt-file">apt-file</a>
+to allow users to determine which package to install to get a specific file.
+<br>
+To activate generating of these files by reprepro, you need a <a href="#contents">Contents</a>
+header in your distribution declaration.
+ </dd>
+ <dt class="dir">COMPONENT1</dt><dd>
+Each component has it's own subdirectory here. They can be named whatever users
+can be bothered to write into their <tt class="filename">sources.list</tt>, but
+things like <tt>main</tt>, <tt>non-free</tt> and <tt>contrib</tt> are common.

+<h3>Package pool</h3>
+While the index files have a required filename, the actual files
+are given just as relative path to the base directory you specify
+in your sources list. That means apt can get them no matter what
+scheme is used to place them. The classical way Debian used till
+woody was to just put them in subdirectories of the
+<tt class="dir">binary-ARCHITECTURE</tt> directories, with the exception
+of the architecture-independent packages, which were put into a
+artificial <tt class="dir">binary-all</tt> directory. This was replaced
+for the official repository with package pools, which reprepro also uses.
+(Actually reprepro stores everything in pool a bit longer than the official
+repositories, that's why it recalculates all filenames without exception).
+<br>
+In a package pool, all package files of all distributions in that repository
+are stored in a common directory hierarchy starting with <tt class="dir">pool/</tt>,
+only separated by the component they belong to and the source package name.
+As everything this has disadvantages and advantages:
+<ul><li>disadvantages
+ <ul><li>different files in different distributions must have different filenames
+ </li><li>it's impossible to determine which distribution a file belongs to by path and filename (think mirroring)
+ </li><li>packages can no longer be grouped together in common subdirectories by having similar functions
+ </li></ul>
+</li><li>advantages
+ <ul><li>the extremely confusing situation of having differently build packages with the same version if different distributions gets impossible by design.
+ </li><li>the source (well, if it exists) is in the same directory as the binaries generated from it
+ </li><li>same files in different distributions need disk-space and bandwidth only once
+ </li><li>each package can be found only knowing component and sourcename
+ </li></ul>
+</li></ul>
+Now let's look at the actual structure of a pool (there is currently no difference
+between the pool structure of official Debian repositories and those generated by
+reprepro):
+
+<dl class="dir">
+<dt class="dir">pool</dt><dd>
+ The directory all this resides in is normally called <tt class="dir">pool</tt>.
+ That's nowhere hard coded in apt but that only looks at the relative
+ directory names in the index files. But there is also no reason to name
+ it differently.
+ <dl class="dir">
+ <dt class="dir">COMPONENT1</dt><dd>
+Each component has it's own subdirectory here.
+They can be named whatever users
+can be bothered to write into their <tt class="filename">sources.list</tt>, but
+things like <tt>main</tt>, <tt>non-free</tt> and <tt>contrib</tt> are common.
+But funny names like <tt>bad</tt> or <tt>universe</tt> are just as possible.
+ <dl class="dir">
+ <dt class="dir">a</dt><dd>
+As there are really many different source packages,
+the directory would be too full when all put here.
+So they are separated in different directories.
+Source packages starting with <tt class="constant">lib</tt> are put into a
+directory named after the first four letters of the source name.
+Everything else is put in a directory having the first letter as name.
+ <dl class="dir">
+ <dt class="dir">asource</dt><dd>
+Then the source package name follows.
+So this directory <tt class="dir">pool/COMPONENT1/a/asource/</tt> would contain
+all files of different versions of the hypothetical package <tt class="constant">asource</tt>.
+ <dl class="dir">
+ <dt class="dir">asource</dt><dd>
+ <dt class="file">a-source_version.dsc</dt>
+ <dt>a-source_version.tar.gz</dt><dd>
+The actual source package consists of its description file (<tt class="suffix">.dsc</tt>)
+and the files references by that.
+ </dd>
+ <dt class="file">binary_version_ARCH1deb</dt>
+ <dt class="file">binary_version_ARCH2.deb</dt>
+ <dt class="file">binary2_version_all.deb</dt><dd>
+ <dt class="file">di-module_version_ARCH1.udeb</dt><dd>
+Binary packages are stored here to.
+So to know where a binary package is stored you need to know what its source package
+name is.
+ </dd>
+ </dl>
+ </dd>
+ </dl>
+ </dd>
+ <dt class="dir">liba</dt><dd>
+As described before packages starting with <tt class="constant">lib</tt> are not stored
+in <tt class="dir">l</tt> but get a bit more context.
+ </dd>
+ </dl>
+ </dd>
+ <dt class="dir">COMPONENT2</dt><dd>
+There is one dir for every component. All look just the same.
+ </dd>
+ </dl>
+</dd></dl>
+As said before, you don't need to know this hierarchy in normal operation.
+reprepro will put everything to where it belong, keep account what is there
+and needed by what distribution or snapshot, and delete files no longer needed.
+(Unless told otherwise or when you are using the low-level commands).
+<h2><a name="config">Config files</a></h2>
+Configuring a reprepro repository is done by writing some config files
+into a directory.
+This directory is currently the <tt class="dir">conf</tt> subdirectory of the
+base directory of the repository,
+unless you specify <tt class="option">--confdir</tt> or set the
+environment variable <tt class="env">REPREPRO_CONFIG_DIR</tt>.
+
+<dl class="dir">
+<dt class="dir">options</dt><dd>
+If this file exists, reprepro will consider each line an additional
+command line option.
+Arguments must be in the same line after an equal sign.
+
+Options specified on the command line take precedence.
+</dd>
+<dt class="dir">distributions</dt><dd>
+This is the main configuration file and the only that is needed in all
+cases.
+It lists the distributions this repository contains and their properties.

+</dd>
+</dl>
+<h2><a name="export">Generation of index files</a></h2>
+<h3>Deciding when to generate</h3>
+As reprepro stores all state in its database,
+you can decide when you want them to be written to the <tt class="dir">dists/</tt>
+directory.
+You can always tell reprepro to generate those files with the <tt>export</tt> command:
+<pre class="command">
+reprepro -b $YOURBASEDIR export $CODENAMES
+</pre>
+This can be especially useful, if you just edited <tt class="file">conf/distributions</tt>
+and want to test what it generates.
+<p>
+While that command regenerates all files, in normal operation reprepro will only
+regenerate files where something just changed or that are missing.
+With <tt class="option">--export</tt> option you can control when this fill happen:
+<dl><dt>never</dt><dd>Don't touch any index files.
+This can be useful for doing multiple operations in a row and not wanting to regenerate
+the indices all the time.
+Note that unless you do an explicit export or change the same parts later without that
+option, the generated index files may be permanently out of date.
+</dd><dt>silent-never</dt><dd>Like never, but be more silent about it.
+</dd><dt>changed</dt><dd>This is the default behaviour since 3.0.1.
+Only export distributions where something changed
+(and no error occurred that makes an inconsistent state likely).
+And in those distributions only (re-)generate files which content should have been changed
+by the current action or which are missing.
+</dd><dt>lookedat</dt><dd>New name for <tt>normal</tt> since 3.0.1.
+</dd><dt>normal</dt><dd>This was the default behaviour until 3.0.0 (changed in 3.0.1).
+In this mode all distributions are processed that were looked at without error
+(where error means only errors happening while the package was open so have a chance
+to cause strange contents).
+This ensures that even after a operation that had nothing to do the looked at
+distribution has all the files exported needed to access it. (But still only files
+missing or that content would change with this action are regenerated).
+</dd><dt>force</dt><dd>Also try to write the current state if some error occurred.
+In all other modes reprepro will not write the index files if there was a problem.
+While this keeps the repository usable for users, it means that you will need an
+explicit export to write possible other changes done before that in the same run.
+(reprepro will tell you that at the end of the run with error, but you should not
+miss it).
+</dd></dl>
+<h3>Distribution specific fields</h3>
+There are a lot of <tt class="file">conf/distributions</tt> headers to control
+what index files to generate for some distribution, how to name
+them, how to postprocess them and so on. The most important are:
+<h4>Fields for the Release files</h4>
+The following headers are copied verbatim to the Release file, if they exist:
+<tt class="header">Origin</tt>,
+<tt class="header">Label</tt>,
+<tt class="header">Codename</tt>,
+<tt class="header">Suite</tt>,
+<tt class="header">Architectures</tt> (excluding a possible value "<tt>source</tt>"),
+<tt class="header">Components</tt>,
+<tt class="header">Description</tt>, and
+<tt class="header">NotAutomatic</tt>,
+<tt class="header">ButAutomaticUpgrades</tt>.
+<h4><a name="compression">Choosing compression and file names</a></h4>
+Depending on the type of the index files, different files are generated.
+No specifying anything is equivalent to:
+<pre class="config">
+ DscIndices Sources Release .gz
+ DebIndices Packages Release . .gz
+ UDebIndices Packages . .gz
+</pre>
+This means to generate <tt>Release</tt>, <tt>Sources.gz</tt> for sources,
+<tt>Release</tt>, <tt>Packages</tt> and <tt>Packages.gz</tt> for binaries
+and <tt>Packages</tt> and <tt>Packages.gz</tt> for installer modules.
+<br>
+The format of these headers is the name of index file to generate, followed
+by the optional name for a per-directory release description
+(when no name is specified, no file is generated).
+Then a list of compressions:
+A single dot (<tt>.</tt>) means generating an uncompressed index,
+<tt>.gz</tt> means generating a gzipped output,
+while <tt>.bz2</tt> requests and bzip2ed file.
+(<tt>.bz2</tt> is not available when disabled at compile time).
+After the compressions a script can be given that is called to generate/update
+additional forms, see <a href="#exporthook">&quot;Additional index files&quot;</a>.
+<h4><a name="signing">Signing</a></h4>
+If there is a <tt class="config">SignWith</tt> header, reprepro will try
+to generate a <tt class="file">Release.gpg</tt> file using libgpgme.
+If the value of the header is <tt>yes</tt> it will use the first key
+it finds, otherwise it will give the option to libgpgme to determine the
+key. (Which means fingerprints and keyids work fine, and whatever libgpgme
+supports, which might include most that gpg supports to select a key).
+<br>
+The best way to deal with keys needing passphrases is to use
+<a href="http://packages.debian.org/gnupg-agent">gpg-agent</a>.
+The only way to specify which keyring to use is to set the
+<tt class="env">GNUPGHOME</tt> environment variable, which will effect all
+distributions.
+<h4><a name="contents">Contents files</a></h4>
+Reprepro can generate files called
+<tt class="file">dists/CODENAME/Contents-ARCHITECTURE.gz</tt>
+listing all files in all binary packages available for the selected
+architecture in that distribution and which package they belong to.
+<br>
+This file can either be used by humans directly or via downloaded
+and searched with tools like
+<a href="http://packages.debian.org/apt-file">apt-file</a>.
+<br>
+To activate generating of these files by reprepro, you need a <tt class="config">Contents</tt> header in that distribution's declaration in <tt class="file">conf/distributions</tt>,
+like:
+<pre class="config">
+Contents:
+</pre>
+Versions before 3.0.0 need a ratio number there, like:
+<pre class="config">
+Contents: 1
+</pre>
+The number is the inverse ratio of not yet looked at and cached files to process in
+every run. The larger the more packages are missing. 1 means to list everything.
+<br>
+The arguments of the Contents field and other fields control
+which Architectures to generate Contents files for and which
+Components to include in those. For example
+<pre class="config">
+Contents: udebs nodebs . .gz .bz2
+ContentsArchitectures: ia64
+ContentsComponents:
+ContentsUComponents: main
+</pre>
+means to not skip any packages, generate Contents for <tt class="suffix">.udeb</tt>
+files, not generating Contents for <tt class="suffix">.deb</tt>s. Also it is only
+generated for the <tt>ia64</tt> architecture and only packages in component
+<tt>main</tt> are included.
+<h4><a name="exporthook">Additional index files (like .diff)</a></h4>
+Index files reprepro cannot generate itself, can be generated by telling
+it to call a script.
+<h5>using rredtool to generate pdiff files</h5>
+Starting with version 4.1.0, the <tt>rredtool</tt> coming with reprepro
+can be used as hook to create and update <tt>Packages.diff/Index</tt> files.
+<br>
+Unlike dak (which created the official Debian repositories) or the pdiff.py
+script (see below) derived from dak, an user will only need to download
+one of those patches, as new changes are merged into the old files.
+<br>
+To use it, make sure you have
+<a href="http://packages.debian.org/diff">diff</a> and
+<a href="http://packages.debian.org/gzip">gzip</a>
+installed.
+Then add something like the following to the headers of the distributions
+that should use this in <tt class="file">conf/distributions</tt>:
+<pre class="config">
+ DscIndices: Sources Release . .gz /usr/bin/rredtool
+ DebIndices: Packages Release . .gz /usr/bin/rredtool
+</pre>
+<h5>the pdiff example hook script (generates pdiff files)</h5>
+This example generates <tt class="file">Packages.diff</tt> and/or
+<tt class="file">Sources.diff</tt> directories containing a set of
+ed-style patches, so that people do not redownload the whole index
+for just some small changes.
+<br>
+To use it, copy <tt class="file">pdiff.example</tt> from the examples directory
+into your <tt class="dir">conf</tt> directory.
+(or any other directory, then you will need to give an absolute path later).
+Unpack, if needed. Rename it to pdiff.py and make it executable.
+Make sure you have
+<a href="http://packages.debian.org/python3-apt">python3-apt</a>,
+<a href="http://packages.debian.org/diff">diff</a> and
+<a href="http://packages.debian.org/gzip">gzip</a>
+installed.
+Then add something like the following to the headers of the distributions
+that should use this in <tt class="file">conf/distributions</tt>:
+<pre class="config">
+ DscIndices: Sources Release . .gz pdiff.py
+ DebIndices: Packages Release . .gz pdiff.py
+</pre>
+More information can be found in the file itself. You should read it.
+<h5>the bzip2 example hook script</h5>
+This is an very simple example.
+Simple and mostly useless,
+as reprepro has built in <tt>.bz2</tt> generation support,
+unless you compiled it your own with <tt>--without-libbz2</tt> or
+with no <tt>libbz2-dev</tt> installed.
+<br>
+To use it, copy <tt class="file">bzip.example</tt> from the examples directory
+into your <tt class="dir">conf</tt> directory.
+(or any other directory, then you will need to give an absolute path later).
+Unpack, if needed. Rename it to bzip2.sh and make it executable.
+Then add something like the following to the headers of the distributions
+that should use this in <tt class="file">conf/distributions</tt>:
+<pre class="config">
+ DscIndices: Sources Release . .gz bzip2.sh
+ DebIndices: Packages Release . .gz bzip2.sh
+ UDebIndices: Packages . .gz bzip2.sh
+</pre>
+The script will compress the index file using the
+<a href="http://packages.debian.org/bzip2">bzip2</a> program and tell
+reprepro which files to include in the Release file of the distribution.

+<h2><a name="localpackages">Local packages</a></h2>
+There are two ways to get packages not yet in any repository into yours.
+<dl><dt>includedsc, includedeb, include</dt><dd>
+These are for including packages at the command line.
+Many options are available to control what actually happens.
+You can easily force components, section and priority and/or choose to
+include only some files or only in specific architectures.
+(Can be quite useful for architecture all packages depending on some
+packages you will some time before building for some of your architectures).
+Files can be moved instead of copied and most sanity checks overwritten.
+They are also optimized towards being fast and simply try things instead of
+checking a long time if they would succeed.
+</dd><dt>processincoming</dt><dd>
+This command checks for changes files in an incoming directory.
+Being optimized for automatic processing (i.e. trying to checking
+everything before actually doing anything), it can be slower
+(as every file is copied at least once to sure the owner is correct,
+with multiple partitions another copy can follow).
+Component, section and priority can only be changed via the distribution's
+override files. Every inclusion needs a <tt class="suffix">.changes</tt> file.
+<br>
+This method is also relatively new (only available since 2.0.0), thus
+optimisation for automatic procession will happen even more.
+</dd></dl>
+<h3><a name="include">Including via command line</a></h3>
+There are three commands to directly include packages into your repository:
+<tt class="command">includedeb</tt>, <tt class="command">includedsc</tt>
+and <tt class="command">includechanges</tt>.
+Each needs to codename of the distribution you want to put your package into
+as first argument and a file of the appropriate type
+(<tt class="suffix">.deb</tt>, <tt class="suffix">.dsc</tt> or
+ <tt class="suffix">.changes</tt>, respectively) as second argument.
+<br>
+If no component is specified via <tt class="option">--component</tt>
+(or short <tt class="option">-C</tt>), it will be guessed looking at its
+section and the components of that distribution.
+<br>
+If there are no <tt class="option">--section</tt>
+(or short <tt class="option">-S</tt>) option, and it is not specified
+by the (binary or source, depending on the type) override file of the
+distribution, the value from the <tt class="suffix">.changes</tt>-file
+is used (if the command is <tt class="command">includechanges</tt>)
+or it is extracted out of the file (if it is a
+<tt class="suffix">.deb</tt>-file, future versions might also try to
+extract it from a <tt class="suffix">.dsc</tt>'s diff or tarball).
+<br>
+Same with the priority and the <tt class="option">--priority</tt>
+(or short <tt class="option">-P</tt>) option.
+<br>
+With the <tt class="option">--architecture</tt> (or short <tt class="option">-A</tt>)
+option, the scope of the command is limited to that architecture.
+<tt class="command">includdeb</tt> will add a Architecture <tt>all</tt>
+packages only to that architecture (and complain about Debian packages for
+other architectures).
+<tt class="command">include</tt> will do the same and ignore packages for
+other architectures (source packages will only be included if the value
+for <tt class="option">--architecture</tt> is <tt>source</tt>).
+<br>
+To limit the scope to a specify type of package, use the
+<tt class="option">--packagetype</tt> or short <tt class="option">-T</tt>
+option. Possible values are <tt>deb</tt>, <tt>udeb</tt> and <tt>dsc</tt>.
+<br>
+When using the <tt class="option">--delete</tt> option, files will
+be moved or deleted after copying them.
+Repeating the <tt class="option">--delete</tt> option will also delete
+unused files.
+<br>
+TO BE CONTINUED.
+<h3><a name="incoming">Processing an incoming queue</a></h3>
+Using the <tt class="command">processincoming</tt> command reprepro
+can automatically process incoming queues.
+While this is still improveable (reprepro still misses ways to send
+mails and especially an easy way to send rejection mails to the
+uploader directly), it makes it easy to have an directory where you
+place your packages and reprepro will automatically include them.
+<br>
+To get this working you need three things:
+<ul>
+<li><a href="#processincoming-incoming-config">
+a file <tt class="file">conf/incoming</tt> describing your incoming directories,
+</a></li>
+<li><a href="#processincoming-dist-config">
+a <tt class="file">conf/distribution</tt> file describing your distributions
+(as always with reprepro)
+and
+</a></li>
+<li><a href="#processincoming-calling">
+a way to get reprepro called to process it.
+</a></li>
+</ul>
+<a name="processincoming-incoming-config">
+<h4>The file <tt class="file">conf/incoming</tt></h4></a>
+describes the different incoming queues.
+As usual the different chunks are separated by empty lines.
+Each chunk can have the following fields:
+<dl><dt>Name</dt><dd>This
+is the name of the incoming queue, that <tt class="command">processincoming</tt>
+wants as argument.</dd>
+<dt>IncomingDir</dt><dd>The actual directory to look for
+<tt class="suffix">.changes</tt> files.</dd>
+<dt>TempDir</dt><dd>To ensure integrity of the processed files and their
+permissions,
+every file is first copied from the incoming directory to this directory.
+Only the user reprepro runs as needs write permissions here.
+It speeds things up if this directory is in the same partition as the pool.
+<dt>Allow</dt><dd>
+This field lists the distributions this incoming queue might inject packages
+into.
+Each item can be a pair of a name of a distribution to accept and a distribution
+to put it into.
+Each upload has each item in its <tt class="field">Distribution:</tt> field
+compared first to last to each of this items and is put in the first distribution
+accepting it. For example
+<pre class="line">
+Allow: stable>etch stable>etch-proposed-updates mystuff unstable>sid
+</pre>
+will put a <tt class="suffix">.changes</tt> file with
+<tt class="field">Distribution: stable</tt> into etch.
+If that is not possible (e.g. because etch has a
+<tt class="field">UploadersList</tt> option not allowing this) it will
+be put into etch-proposed-updates.
+And a <tt class="suffix">.changes</tt> file with
+<tt class="field">Distribution: unstable</tt> will be put into sid, while
+with <tt class="field">Distribution: mystuff</tt> will end up in mystuff.
+<br>
+If there is a <tt class="field">Default</tt> field, the <tt class="field">Allow</tt>
+field is optional.</dd>
+<dt>Default</dt><dd>
+Every upload not caught by an item of the <tt class="field">Allow</tt>
+field is put into the distribution specified by this.
+<br>

+<h4><tt class="file">conf/distribution</tt> for <tt class="command">processincoming</tt></h4></a>
+There are no special requirements on the <tt class="file">conf/distribution</tt>
+file by processincoming. So even a simple
+<pre class="file">
+Codename: mystuff
+Architectures: i386 source
+Components: main non-free contrib bad
+</pre>
+will work.
+<br>
+The <tt class="field">Uploaders</tt> field can list a file limiting

+in <tt class="file">conf/incoming</tt>'s <tt class="field">Allow</tt>

+<a name="processincoming-calling">
+<h4>Getting <tt class="command">processincoming</tt> called.</h4></a>
+While you can just call <tt class="command">reprepro processincoming</tt> manually,
+having an incoming queue needing manual intervention takes all the fun out of
+having an incoming queue, so usually so automatic way is chosen:
+<ul>
+<li>Dupload and dput have ways to call an hook after an package was uploaded.
+This can be an ssh to the host calling reprepro.
+The disavantage is having to configure this in every
+<tt class="file">.dupload.conf</tt> on every host you want to upload and give
+everyone access to ssh and permissions on the archive who should upload.
+The advantage is you can configure reprepro to have interactive scripts or
+ask for passphrases.
+</li>
+<li>Install a cron-job calling reprepro every 5 minutes. Cron is usually
+available everywhere and getting the output sent by mail to you or a mailing
+list is easy.
+The annoying part is having to wait almost 5 minutes for the processing.
+</li>
+<li>Use something like <a href="http://packages.debian.org/inoticoming"><tt class="external">inoticoming</tt></a>.
+Linux has a syscall called inotify, allowing a program to be run whenever
+something happens to a file.
+One program making use of this is inoticoming. It watches a directory using
+this facility and whenever a <tt class="suffix">.changes</tt> file is completed
+it can call reprepro for you.
+(As this happens directly, make sure you always upload the <tt class="suffix">.changes</tt>
+file last, dupload and dput always ensure this).
+This can be combined with Debian's cron-extension to have a program started at
+boot time with the <tt>@reboot</tt> directive.
+For example with a crontab like:
+<pre class="file">
+MAILTO=myaddress@somewhere.tld
+
+@reboot inoticoming --logfile /my/basedir/logs/i.log /my/basedir/incoming/ --stderr-to-log --stdout-to-log --suffix '.changes' --chdir /my/basedir reprepro -b /my/basedir --waitforlock 100 processincoming local {} \;
+</pre>
+</li>
+</ul>
+<h2><a name="mirroring">Mirroring / Updating</a></h2>
+Reprepro can fetch packages from other repositories.
+For this it uses apt's methods from <tt class="dir">/usr/lib/apt/methods/</tt>
+so everything (http, ftp, ...) that works with apt should also work with reprepro.
+Note that this works on the level of packages, even though you can tell reprepro
+to create a distribution having always the same packages as some remote repository,
+the repository as a whole may not look exactly the same but only have the same set
+of packages in the same versions.
+<br>
+You can also only mirror a specific subset of packages, merge multiple repositories
+into one distribution, or even have distributions mixing remote and local packages.
+<br>
+Each distribution to receive packages from other repositories needs an
+<tt class="field">Update:</tt> field listing the update rules applied to it.
+Those update rules are listed in <tt class="file">conf/updates</tt>.
+There is also the magic <tt>-</tt> update rule, which tells reprepro to delete
+all packages not re-added by later rules.
+<br>
+To make reprepro to update all distributions call <tt>reprepro update</tt>
+without further arguments, or give the distributions to update as additional
+arguments.
+<br>
+Let's start with some examples:
+<h3><a name="update-examples">Updating examples</a></h3>
+Let's assume you have the following <tt class="file">conf/distributions</tt>
+<pre class="file">
+Codename: etch
+Architectures: i386 source
+Components: main contrib
+Update: local - debian security
+
+Codename: mystuff
+Architectures: abacus source
+Components: main bad
+Update: debiantomystuff
+</pre>
+and the following <tt class="file">conf/updates</tt>
+<pre class="file">
+Name: local
+Method: http://ftp.myorg.tld/debian
+
+Name: debian
+Method: http://ftp.de.debian.org/debian
+VerifyRelease: A70DAF536070D3A1
+Config: Acquire::Http::Proxy=http://proxy.yours.org:8080
+
+Name: security
+Suite: */updates
+Method: http://security.eu.debian.org/
+Fallback: http://security.debian.org/
+VerifyRelease: A70DAF536070D3A1
+Config: Acquire::Http::Proxy=http://proxy.yours.org:8080
+
+Name: debiantomystuff
+Suite: sid
+Method: http://ftp.de.debian.org/debian
+Architectures: i386&gt;abacus source
+Components: main non-free&gt;bad contrib&gt;bad
+FilterFormula: Architecture (== all)| !Architecture
+FilterList: deinstall list
+</pre>
+and a file <tt class="file">conf/list</tt> with some
+output as <tt>dpkg --get-selections</tt> is printing.
+<br>
+If you then run
+<tt class="command">reprepro update etch</tt> or
+<tt class="command">reprepro checkupdate etch</tt>,
+reprepro looks at etch's <tt class="field">Update:</tt> line
+and finds four rules. The first is the <tt>local</tt> rule,
+which only has a method, so that means it will download the
+<tt class="file">Release</tt> file from
+<tt>http://ftp.myorg.tld/debian/dists/etch/Release</tt> and
+(unless it already has downloaded them before or that
+repository does not have all of them) downloads the
+<tt>binary-i386/Packages.gz</tt>
+and <tt>source/Sources.gz</tt> files for main and contrib.
+The same is done for the <tt>debian</tt> and <tt>security</tt>
+rules.
+As they have a <tt class="field">VerifyRelease</tt> field,
+Release.gpg is also downloaded and checked to be signed with the
+given key
+(which you should have imported to you <tt class="external">gpg</tt>
+keyring before).
+As security has a <tt class="field">Suite:</tt> field, not the codename,
+but the content of this field (with an possible<tt>*</tt> replaced by the codename),
+is used as distribution to get.
+<br>
+Then it will parse for each part of the distribution, parse the files it
+get from left to right.
+For each package it starts with the version currently in the distribution,
+if there is a newer on in <tt>local</tt> it will mark this.
+Then there is the delete rule <tt>-</tt>, which will mark it to be deleted
+(but remembers what was there, so if later the version in the distribution
+or the version in <tt>local</tt> are newest, it will get them from here avoiding
+slow downloads from far away). Then it will look into <tt>debian</tt> and then
+in <tt>security</tt>, if they have a newer version (or the same version, clearing
+the deletion mark).
+<br>
+If you issued <tt class="command">checkupdate</tt> reprepro will print what it would
+do now, otherwise it tries to download all the needed files and when it got all,
+change the packages in the distribution to the new ones, export the index files
+for this distribution and finally delete old files no longer needed.
+<br>
+TO BE CONTINUED.
+<h2><a name="propagation">Propagation of packages</a></h2>
+You can copy packages between distributions using the
+<tt class="command">pull</tt> and <tt class="command">copy</tt> commands.
+<br>
+With the <tt class="command">copy</tt> command you can copy packages
+by name from one distribution to the other within the same repository.
+<br>
+With the <tt class="command">pull</tt> command you can pull all packages
+(or a subset defined by some list, or exceptions by some list, or by some
+formula, or ...) from one distribution to another within the same formula.
+<br>
+Note that both assume the filenames of the corresponding packages in the
+pool will not differ, so you cannot move packages from one component to another.
+<br>
+Let's just look at a little example, more information can be found in the man page.
+<br>
+Assume you upload all new packages to a distribution and you want another
+so you can keep using an old version until you know the newer works, too.
+One way would be to use something like the following
+<tt class="file">conf/distributions</tt>:
+<pre class="file">
+Codename: development
+Suite: unstable
+Components: main extra
+Architectures: i386 source
+
+Codename: bla
+Suite: testing
+Components: main extra
+Architectures: i386 source
+Pull: from_development
+</pre>
+and <tt class="file">conf/pulls</tt>:
+<pre class="file">
+Name: from_development
+From: development
+</pre>
+i.e. you have two distributions, bla and development.
+Now you can just upload stuff to development (or it's alias unstable).
+And when you want a single package to go to testing, you can use the copy
+command:
+<pre class="shell">
+reprepro copy bla development name1 name2 name3
+</pre>
+If you do not want to copy all packages of a given name, but only some
+of them, you can use <tt>-A</tt>, <tt>-T</tt> and <tt>-C</tt>:
+<pre class="shell">
+reprepro -T deb -A i386 copy bla development name1
+</pre>
+will copy <tt class="suffix">.deb</tt> packages called name1 from the i386
+parts of the distribution.
+<br>

+<h2><a name="snapshosts">Snapshots</a></h2>
+There is a gensnapshot command.<br>
+TO BE DOCUMENTED
+<h2><a name="tracking">Source package tracking</a></h2>
+TO BE DOCUMENTED
+<h2><a name="hooks">Extending reprepro / Hooks and more</a></h2>
+When reprepro misses some functionality,
+it often can be added by some kind of hook.
+<br>
+Currently you can execute your own scripts at the following occasions:
+<ul>
+<li><a href="#addhook">after adding or removing packages</a></li>
+<li><a href="#byhandhook">to process byhand files</a></li>
+<li><a href="#exporthook">when creating index files (Packages.gz, Sources.gz)</a></li>
+<li><a href="#signhook">when signing releases</a></li>
+<li><a href="#outhook">after changing the visible files of the repository managed</a></li>
+<li><a href="#endhook">when reprepro finished</a></li>
+</ul>
+<h3><a name="addhook">Scripts to be run when adding or removing packages</a></h3>
+Whenever a package is added or removed,
+you can tell reprepro to log that to some file and/or call a script using the
+<tt>Log:</tt> directive in <tt class="file">conf/distributions</tt>.
+<br>
+This script can send out mails and do other logging stuff,
+but despite the name, it is not restricted to logging.
+<br>
+<h4>Automatically extracting changelog and copyright information</h4>
+reprepro ships with an example script to extract <tt class="file">debian/changelog</tt>
+and <tt class="file">debian/copyright</tt>
+files from source packages into a hierarchy loosely resembling the way changelogs
+are made available at
+<a href="http://packages.debian.org/changelogs/">http://packages.debian.org/changelogs/</a>.
+<br>
+All you have to do is to copy (or unpack if compressed) the file
+<tt class="file">changelogs.example</tt> from the examples directory
+in the reprepro source or
+<a href="file:///usr/share/doc/reprepro/examples/">/usr/share/doc/reprepro/examples/</a>
+of your installed reprepro package into your <tt class="directory">conf/</tt> directory
+(or somewhere else, then you will need an absolute path later), perhaps
+change some directories specified in it
+and add something like the following lines
+to all distributions in <tt class="file">conf/distributions</tt> that should use
+this feature:
+<pre class="config">
+Log:
+ --type=dsc changelogs.example
+</pre>
+If you still want to log to some file, just keep the filename there:
+<pre class="config">
+Log: mylogfilename
+ --type=dsc changelogs.example
+</pre>
+Then cause those files to be generated for all existing files via
+<pre class="command">
+reprepro rerunnotifiers
+</pre>
+and all future source packages added or removed will get this list automatically
+updated.
+<h4>Writing your own Log: scripts</h4>
+You can list an arbitrary amount of scripts, to be called at specified times
+(which can overlap or even be the same):
+<pre class="config">
+Log: logfilename
+ --type=dsc script-to-run-on-source-package-changes
+ script-to-run-on-package-changes
+ another-script-to-run-on-package-changes
+ --type=dsc --component=main script-to-run-on-main-source-packages
+ --architecture=i386 --type=udeb script-to-run-on-i386-udebs
+ --changes script-to-run-on-include-or-processincoming
+</pre>
+There are two kind of scripts:
+The first one is called when a package was added or removed.
+Using the <tt class="option">--archtecture=</tt>,
+<tt class="option">--component=</tt> and
+<tt class="option">--type=</tt> options you can limit it to specific parts
+of the distribution.
+The second kind is marked with <tt class="option">--changes</tt> and is
+called when a <tt class="suffix">.changes</tt>-file was added with
+<tt class="command">include</tt> or <tt class="command">processincoming</tt>.
+Both are called asynchronous in the background <emph>after</emph> everything was done,
+but before no longer referenced files are deleted (so the files of the
+replaced or deleted package are still around).
+<h5>Calling conventions for package addition/removal scripts</h5>
+This type of script is called with a variable number of arguments.
+The first argument is the action. This is either
+<tt>add</tt>, <tt>remove</tt> or <tt>replace</tt>.
+The next four arguments are the codename of the affected distribution
+and the packagetype, component and architecture in that distribution
+affected.
+The sixth argument is the package's name.
+After that is the version of the added package (<tt>add</tt> and <tt>replace</tt>)
+and the version of the removed package (<tt>remove</tt> and <tt>replace</tt>).
+Finally the filekeys of the new (<tt>add</tt> and <tt>replace</tt>) and/or
+removed (<tt>remove</tt> and <tt>replace</tt>) package are listed
+starting with the marker &quot;<tt>--</tt>&quot; followed by each filekey
+(the name of the file in the <tt class="dir">pool/</tt>
+relative to <tt class="env">REPREPRO_OUT_DIR</tt>)
+as its own argument.
+<br>
+The environment variable <tt class="env">REPREPRO_CAUSING_COMMAND</tt>
+contains the command of the action causing this change.
+The environment variable
+<tt class="env">REPREPRO_CAUSING_FILE</tt> contains the name of the file
+given at the command line causing this package to be changed,
+if there is one.
+(i.e. with <tt class="command">includedeb</tt>,
+<tt class="command">includedsc</tt> and <tt class="command">include</tt>).
+The environment variables
+<tt class="env">REPREPRO_CAUSING_RULE</tt> and
+<tt class="env">REPREPRO_FROM</tt> are
+the name of the update or pull rule pulling in a package
+and the name of the distribution a package is coming from.
+What this name is depends on the command and for most commands
+it is simply not set at all.
+And of course all the <tt class="env">REPREPRO_*_DIR</tt> variables are set.
+<h5>Calling conventions for <tt class="suffix">.changes</tt> scripts</h5>
+This type of script is called with 5 or 6 arguments.
+The first is always &quot;<tt>accepted</tt>&quot;, to make it easier to
+check it is configured the right way.
+The second argument is the codename of the distribution the
+<tt class="suffix">.changes</tt>-file was added to.
+The third argument is the source name, the forth the version.
+The fifth name is the <tt class="suffix">.changes</tt> itself
+(in case of <tt class="command">processingcoming</tt> the secure copy in the
+temporary dir).
+There is a sixth argument if the <tt class="suffix">.changes</tt>-file was
+added to the <tt class="dir">pool/</tt>:
+The filekey of the added .changes file
+(i.e. the filename relative to <tt class="env">REPREPRO_OUT_DIR</tt>).
+<br>
+The environment variable <tt class="env">REPREPRO_CAUSING_COMMAND</tt>
+contains the command of the action causing this change.
+The environment variable
+<tt class="env">REPREPRO_CAUSING_FILE</tt> contains the name of the file
+given at the command line, if there is one
+(e.g. with <tt class="command">include</tt>).
+And of course all the <tt class="env">REPREPRO_*_DIR</tt> variables are set.
+<h3><a name="byhandhook">Scripts to be run to process byhand files</a></h3>
+<tt class="suffix">.changes</tt> files can (beside the usual packages files
+to be included in the repository) contain additional files to be processed
+specially.
+Those are marked by the special section <tt class="constant">byhand</tt> (in Debian)
+or <tt class="constant">raw-</tt>something (in Ubuntu).
+Besides storing them just in the pool besides the packages using the
+<tt class="constant">includebyhand</tt> value in the <tt class="field">Tracking</tt>
+settings you can also let reprepro process a hook to process them when encountering
+them in the <tt class="action">processincomming</tt> action
+(Typical usages are uploading documentation files this way that are unpacked next
+to the repository, or installer images or stuff like that).
+
+To use them add to the distribution's defining stanca in <tt class="filename">conf/distributions</tt> a field like:
+<pre class="config">
+ByhandHooks:
+ byhand * manifesto.txt handle-byhand.sh
+</pre>
+This will call the hook script <tt class="constant">handle-byhand.sh</tt> for every byhand file with section <tt class="constant">byhand</tt>, any priority and filename <tt class="constant">manifesto.txt</tt>. (The first three fields allow glob characters for matching).
+
+The script will then be called with 5 arguments:
+the codename of the distribution,
+the section,
+the priority,
+the filename as found in the changes file and
+the filename of where the script can find the actual file.
+
+<h3>Scripts to be run when creating index files (Packages.gz, Sources.gz)</h3>
+this hook is described in the section <a href="#exporthook">&quot;Additional index files&quot;</a>.
+
+<h3><a name="signhook">Scripts to be run when signing releases</a></h3>
+Instead of creating <tt class="filename">InRelease</tt> and
+<tt class="filename">Release.gpg</tt> files using libgpgme,
+the <tt class="option">SignWith</tt> option can also contain
+a exclamation mark followed by a space and the name of a hook script to call.
+
+The script gets three arguments:
+The filename to sign,
+the filename of the InRelease file to create and
+the filename of the Release.gpg to create
+(a Release.gpg does not need to be created. reprepro will assume you do not care about that legacy file if it is not created).
+
+Reprepro will wait for the script to continue and only do the renaming
+and deleting of old files after that, so the script might wait for example
+for someone to copy files from the system, signing and copying them it,
+for example.
+
+<h3><a name="outhook">Scripts to be run after changing the visible files of the repository managed</a></h3>
+When using the <tt class="option">--outhook</tt> command line option (or the corresponding
+<tt class="constant">outhook</tt> in the <tt class="filename">options</tt> file),
+reprepro will create a <tt class="suffix">.outlog</tt> file in the log directory describing
+any changes done to the out dir and calls the hook script given as argument with this
+file as argument.
+
+The <tt class="suffix">.outlog</tt> file consists of lines each starting with a keyword
+and then some arguments separated by tab characters.
+
+The possible keywords are:
+<ul>
+<li><tt class="constant">POOLNEW</tt>:
+One argument is the filekey of a file newly added to the pool.
+<li><tt class="constant">POOLDELETE</tt>:
+One argument is the filekey of a file removed from the pool.
+<li><tt class="constant">START-DISTRIBUTION</tt>, <tt class="constant">END-DISTRIBUTION</tt>:
+two or three arguments: the codename, the directory,
+and the suite (if set).
+<li><tt class="constant">START-SNAPSHOT</tt>, <tt class="constant">END-SNAPSHOT</tt>:
+three arguments: the codename, the directory, and the name of the snapshot generated.
+<li><tt class="constant">DISTFILE</tt>:
+three arguments: the directory of the distribution (relative to out dir), the name relative to that directory, and the filename generated by reprepro.
+<li><tt class="constant">DISTSYMLINK</tt>:
+three arguments: the directory of the distribution (relative to out dir), the name relative to that directory, and the symlink target (relative to that directory).
+<li><tt class="constant">DISTDELETE</tt>:
+two arguments: the directory of the distribution (relative to out dir), the name relative to that directory of a file no longer there.
+<li><tt class="constant">DISTKEEP</tt> (not yet generated):
+two arguments: the directory of the distribution (relative to out dir), the name relative to that directory.
+</ul>
+
+All <tt class="constant">POOLNEW</tt> come before any distribution changes referencing them
+and all <tt class="constant">POOLDELETE</tt> will be afterwards.
+Each line belonging to a distribution is guaranteed to be between the corresponding
+<tt class="constant">START-DISTRIBUTION</tt> and
+<tt class="constant">END-DISTRIBUTION</tt> or between a
+<tt class="constant">START-SNAPSHOT</tt> and
+<tt class="constant">END-SNAPSHOT</tt> or between a
+with the same directory
+(i.e. there is some redundancy so you can choose to parse the information where it is more convenient for you).
+
+The lines starting with <tt class="constant">DIST</tt> describe new or modified files in the distribution description exported by reprepro. No hint is given if that file was previously non-existent, a proper file or a symlink (i.e. if you copy stuff, do not make any assumptions about that).
+Future versions of reprepro might create <tt class="constant">DISTKEEP</tt> lines to denote files that have not changed (i.e. just ignore those lines to be future-proof).
+
+The directories for the distribution entries are what apt expects them (i.e. always starting with <tt class="constant">dists/</tt>, while the third argument to <tt class="constant">DISTFILE</tt> is the name reprepro generated (i.e. starts with the distdir value, which can be configured to not end with <tt class="constant">dists/</tt>).
+
+<h3><a name="endhook">when reprepro finished</a></h3>
+With the <tt class="option">--endhook</tt> command line option (or the corresponding
+<tt class="constant">endhook</tt> in the <tt class="filename">options</tt> file) you
+can specify a hook to be executed after reprepro finished but before reprepro returns
+the to calling process.
+The hook gets all the command line arguments after the options (i.e. starting with
+the name of the action) and the exit code reprepro would have produces.
+For an example see the man page.
+<h2><a name="maintenance">Maintenance</a></h2>
+This section lists some commands you can use to check and improve the health
+of you repository.
+<br>
+Normally nothing of this should be needed, but taking a look from time to time
+cannot harm.
+<pre class="command">
+reprepro -b $YOURBASEDIR dumpunreferenced
+</pre>
+This lists all files reprepro knows about that are not marked as needed by anything.
+Unless you called reprepro with the <tt class="option">--keepunreferenced</tt>
+option, those should never occur. Though if reprepro is confused or interrupted it
+may sometimes prefer keeping files around instead of deleting them.
+<pre class="command">
+reprepro -b $YOURBASEDIR deleteunreferenced
+</pre>
+This is like the command before, only that such files are directly forgotten and
+deleted.
+<pre class="command">
+reprepro -b $YOURBASEDIR check
+</pre>
+Look if all needed files are in fact marked needed and known.
+<pre class="command">
+reprepro -b $YOURBASEDIR checkpool
+</pre>
+Make sure all known files are still there and still have the same checksum.
+<pre class="command">
+reprepro -b $YOURBASEDIR checkpool fast
+</pre>
+As the command above, but do not compute checksums.
+<pre class="command">
+reprepro -b $YOURBASEDIR tidytracks
+</pre>
+If you use source package tracking, check for files kept because of this
+that should no longer by the current rules.
+<br>
+If you fear your tracking data could have became outdated,
+you can also try the retrack command:
+<pre class="command">
+reprepro -b $YOURBASEDIR retrack
+</pre>
+That refreshes the tracking information about packages used and then
+runs a tidytracks. (Beware: don't do this with reprepro versions before 3.0.0).
+<h2><a name="internals">Internals</a></h2>
+reprepro stores the data it collects in Berkeley DB file (<tt class="suffix">.db</tt>)
+in a directory called <tt class="dir">db/</tt> or whatever you specified via command
+line. With a few exceptions, those files are NO CACHES, but the actual data.
+While some of those data can be regained when you lose those files, they are better
+not deleted.
+<h3>packages.db</h3>
+This file contains the actual package information.
+<br>
+It contains a database for every (codename,component,architecture,packagetype) quadruple
+available.
+<br>
+Each is indexed by package name and essentially contains the information written do
+the Packages and Sources files.
+<br>
+Note that if you change your <tt class="file">conf/distributions</tt> to no longer
+list some codenames, architectures or components,
+that will not remove the associated databases in this file.
+That needs an explicit call to <tt class="command">clearvanished</tt>.
+<h3>references.db</h3>
+This file contains a single database that lists for every file why this file
+is still needed.
+This is either an identifier for a package database, an tracked source package,
+or a snapshot.
+<br>
+Some low level commands to access this are (take a look at the manpage for how to use them):

+<h3>files.db / checksums.db</h3>
+These files contains what reprepro knows about your <tt class="dir">pool/</tt> directory,
+i.e. what files it things are there with what sizes and checksums.
+The file <tt class="filename">files.db</tt> is used by reprepro before version 3.3
+and kept for backwards compatibility.
+If your repository was only used with newer versions you can safely delete it.
+Otherwise you should run <tt class="command">collectnewchecksums</tt> before deleting
+it.
+The file <tt class="filename">checksums.db</tt> is the new file used since
+version 3.3.
+It can store more checksums types (<tt class="filename">files.db</tt> only contained
+md5sums, <tt class="filename">checksums.db</tt> can store arbitrary checksums and
+reprepro can even cope with it containing checksum types it does not yet know of)
+but for compatibility with pre-3.3 versions is not the canonical source of information
+as long as a <tt class="filename">files.db</tt> file exists).
+<br>
+If you manually put files in the pool or remove them, you should tell reprepro about that.
+(it sometimes looks for files there without being told, but it never forgets files
+except when it would have deleted them anyway).
+Some low level commands (take a look at the man page for how to use them):
+<dl class="commands">
+<dt class="command">collectnewchecksums</dt><dd>Make sure every file is listed in <tt class="filename">checksums.db</tt> and with all checksum types your reprepro supports.</dd>
+<dt class="command">checkpool fast</dt><dd>Make sure all files are still there.</dd>
+<dt class="command">checkpool</dt><dd>Make sure all files are still there and correct.</dd>
+<dt class="command">dumpunreferenced</dt><dd>Show all known files without reference.</dd>
+<dt class="command">deleteunreferenced</dt><dd>Delete all known files without reference.</dd>
+<dt class="command">_listmd5sums</dt><dd>Dump this database (old style)</dd>
+<dt class="command">_listchecksums</dt><dd>Dump this database (new style)</dd>
+<dt class="command">_detect</dt><dd>Add files to the database</dd>
+<dt class="command">_forget</dt><dd>Forget that some file is there</dd>
+<dt class="command">_addmd5sums</dt><dd>Create the database from dumped data</dd>
+<dt class="command">_addchecksums</dt><dd>dito</dd>
+<h3>release.cache.db</h3>
+In this file reprepro remembers what it already wrote to the <tt class="dir">dists</tt>
+directory,
+so that it can write their checksums (including the checksums of the uncompressed variant,
+even if that was never written to disk)
+in a newly to create <tt class="file">Release</tt>
+file without having to trust those files or having to unpack them.
+<h3>contents.cache.db</h3>
+This file contains all the lists of files of binary package files where reprepro
+already needed them. (which can only happen if you requested Contents files to be
+generated).
+<h3>tracking.db</h3>
+This file contains the information of the <a href="#tracking">source package tracking</a>.
+<h2><a name="recovery">Disaster recovery</a></h2>
+TO BE DOCUMENTED (see the
+<a href="http://git.debian.org/?p=mirrorer/reprepro.git;a=blob_plain;f=docs/recovery;hb=HEAD">recovery</a>
+file until then)
+<h2><a name="paranoia">Paranoia</a></h2>
+As all software, reprepro might have bugs.
+And it uses libraries not written by myself,
+which I'm thus even more sure that they will have bugs.
+Some of those bugs might be security relevant.
+This section contains some tips, to reduce the impact of those.
+<ul>
+<li>Never run reprepro as root.<br>
+All reprepro needs to work are permissions to files,
+there is no excuse for running it as root.
+</li>
+<li>Don't publish your db/ directory.<br>
+The contents of the db directory are not needed by everyone else.
+Having them available to everyone may make it easier for them to
+exploit some hypothetical problem in libdb and makes it easier to
+know in advance how exactly reprepro will act in a given circumstances,
+thus easier to exploit some hypothetical problem.
+</li>
+<li>Don't accept untrusted data without need.<br>
+If an attacker cannot do anything, they cannot do anything harmful, either.
+So if there is no need, don't offer an anonymous incoming queue.
+<tt class="program">dput</tt> supports uploading via scp, so just having
+an only group-writable incoming directory, or even better multiple incoming
+directories can be a better alternative.
+</li>
+</ul>
+External stuff being used and attack vectors opened by it:
+<dl>
+<dt>libgpgme/gpg</dt><dd>
+Almost anything is run through <tt>libgpgme</tt> and thus <tt>gpg</tt>.
+It will be used to check the <tt class="filename">Release.gpg</tt> file,
+or to read <tt class="suffix">.dsc</tt> and <tt class="suffix">.changes</tt>
+files (even when there is no key to look for specified,
+as that is the best way to get the data from the signed block).
+Avoiding this by just accepting stuff without looking for signatures on
+untrusted data is not really an option, so I know nothing to prevent this
+type of problems.
+</dd>
+<dt>libarchive</dt><dd>
+The <tt class="suffix">.tar</tt> files within <tt class="suffix">.deb</tt>
+files are normally (unless that library was
+not available while compiling) read using libarchive.
+This happens when a <tt class="suffix">.deb</tt> file is to be added
+(though only after deciding if it should be added, so if it does not have
+the correct checksum or the .changes did not have the signatures you specified,
+it is not) or when the file list is to be extracted
+(when creating <tt class="filename">Contents</tt> files).
+Note that they are not processed when only mirroring them (of course unless
+<tt class="filename">Contents</tt> files are generated), as then only the
+information from the Packages file is copied.
+</dd>
+<dt>dpkg-deb/tar</dt><dd>
+If reprepro was compiled without libarchive,
+<tt class="program">dpkg-deb</tt> is used instead, which most likely will
+call <tt class="program">tar</tt>. Otherwise just the same like the last
+item.
+</dd>
+<dt>zlib</dt><dd>
+When mirroring packages, the downloaded
+<tt class="filename">Packages.gz</tt> and <tt class="filename">Sources.gz</tt> files
+are read using zlib. Also the generated <tt class="suffix">.gz</tt> files
+are generated using it. There is no option but hoping there is no security
+relevant problem in that library.
+</dd>
+<dt>libbz2</dt><dd>
+Only used to generate <tt class="suffix">.bz2</tt> files.
+If you fear simple blockwise writing using that library has a security problem
+that can be exploited by data enough harmless looking to be written to the
+generated index files, you can always decide to no tell reprepro to generate
+<tt class="suffix">.bz2</tt> files.
+</dd>
+</dl>
+<h2><a name="counterindications">What reprepro cannot do</a></h2>
+There are some things reprepro does not do:
+<dl><dt>Verbatim mirroring</dt><dd>
+Reprepro aims to put all files into a coherent <tt>pool/</tt> hierarchy.
+Thus it cannot guarantee that files will have the same relatives path as in the
+original repository (especially if those have no pool).
+It also creates the index files from its own indices.
+While this leads to a tidy repository and possible savings of disk-space, the
+signatures of the repositories you mirror cannot be used to authenticate the mirror,
+but you will have to sign (or tell reprepro to sign for you) the result.
+While this is perfect when you only mirror some parts or specific packages or
+also have local packages that need local signing anyway, reprepro is no suitable tool
+for creating a full mirror that can be authenticated without adding the key of this
+repository.
+</dd>
+<dt>Placing your files on your own</dt><dd>
+Reprepro does all the calculation of filenames to save files as,
+bookkeeping what files are there and what are needed and so on.
+This cannot be switched off or disabled.
+You can place files where reprepro will expect them and reprepro will use
+them if their md5sum matches.
+But reprepro is not suited if you want those files outside of a pool or in
+places reprepro does not consider their canonical ones.
+</dd>
+<dt>Having different files with the same name</dt><dd>
+take a look in the <a href="http://git.debian.org/?p=mirrorer/reprepro.git;a=blob_plain;f=docs/FAQ;hb=HEAD">FAQ</a> (currently question 1.2) why and how to avoid the problem.

+# generates partial package updates list as reprepro hook
+# (to be used by apt-get >= 0.6.44, apt-qupdate or things compatible with that)
+
+# changes Copyright 2005 Bernhard R. Link <brlink@debian.org>
+# as this is used as hook, it does not need any parsing of
+# Configuration or Handling of architectures and components.
+# Also reprepro will present old and new file, so it does not
+# need to store a permanent copy of the last version.
+# This needs either python3-apt installed or you have to change
+# it to use another sha1 calculation method.
+
+# HOW TO USE:
+# - install python3-apt
+# - make sure your paths contain no ' characters.
+# - be aware this is still quite experimental and might not
+# report some errors properly
+# - uncompress this file if it is compressed
+# - copy this file to your conf/ directory as "pdiff"
+# - make it executable
+# - add something like the following to the every distribution
+# in conf/distributions you want to have diffs for:
+#
+# DscIndices: Sources Release . .gz pdiff
+# DebIndices: Packages Release . .gz pdiff
+#
+# The first line is for source indices, the second for binary indices.
+# Make sure uncompressed index files are generated (the single dot in those
+# lines), as this version only diffs the uncompressed files.

+files in your --dbdir (normally db/):
+
+1) references.db
+This file only contains the information which file in the pool/
+is needed by which target (i.e. which type/distribution/
+component/architecture quadruple). This is simply repairable by
+deleting references.db and running "rereference".
+
+The current state of this database can be seen with "dumpreferences".
+All references from some specific target can be removed with
+"_removereferences".
+
+2) files.db and checksums.db
+These files contain the information about which files in the pool/ dir
+are known and what checksums they have. Files not in here will not be
+deleted with "deleteunreferenced". Files being wrong here will not realized
+(and thus not corrected even if told to be newly included)
+
+If both files exist, files.db is the canonical information and checksums.db
+can be regenerated with a call to collectnewchecksums.
+If only checksums.db is there, only that it used. (This means: if you
+have called collectnewchecksums since you last used a version prior to 3.3
+with this repository, you can just delete files.db. But make sure to
+never ever use a version prior to 3.0 on this repository after that.)
+
+To get this database in text form use "_listchecksums" without argument,
+to add items manually pipe it into "_addchecksums". (Filenames
+are handled as strings, so be careful).
+
+If the database is completely lost or broken, you can regain it by moving
+files.db and checksums.db out of the way and running:
+find $BASEDIR/pool -type f -printf "pool/%P\n" | reprepro -b $BASEDIR _detect
+(or cd $BASEDIR && find pool -type f -print | reprepro -b . _detect)
+
+Also single files can be removed or added by "_forget" and "_detect".
+(Again note filekeys will be handled as strings, so leading "./", double
+ slashes, "/./", symlinks and the like make them differ).
+
+4) packages.db
+This file contains multiple databases, one for each target, containing
+the chunks from the Packages or Sources files, indexed by package name.
+
+This one is the hardest to reconstruct. If you have still an uncorrupted
+"dists/" directory around, (e.g. you just deleted db/ accidentally),
+it can be reconstructed by moving your dists/ directory to some other place,
+moving the packages.db file (if still existent) away, and set every distribution
+in conf/distributions a "Update: localreadd" with localreadd in conf/updates like:
+Name: localreadd
+Suite: *
+Method: copy:/<otherplace>
+
+with otherplace being the place you moved the dists/ directory too.
+
+If the packages database is corrupt, the described way can at least reconstruct
+the Packages still landing in the Packages.gz and Sources.gz files.
+If references.db is still accessible via dumpreferences, it can give hints
+where the other files belong to. Otherwise removing references.db and calling
+"rereference" and then "dumpunreferenced" will give you a list of files not
+yet anywhere.
+
+Last but not least, there are also the "check" and "checkpool" commands, which
+can give some hints about inconsistencies. (Check will also read files missing
+from files.db+checksums.db if they are needed by packages but in the pool).

+.TH REPREPRO 1 "2013-05-04" "reprepro" REPREPRO
+.SH NAME
+reprepro \- produce, manage and sync a local repository of Debian packages
+.mso www.tmac
+.SH SYNOPSIS
+.B reprepro \-\-help
+
+.B reprepro
+[
+\fIoptions\fP
+]
+\fIcommand\fP
+[
+\fIper\-command\-arguments\fP
+]
+.SH DESCRIPTION
+reprepro is a tool to manage a repository of Debian packages
+(.deb, .udeb, .dsc, ...).
+It stores files either being injected manually or
+downloaded from some other repository (partially) mirrored
+into a pool/ hierarchy.
+Managed packages and checksums of files are stored in a
+Berkeley DB database file,
+so no database server is needed.
+Checking signatures of mirrored repositories and creating
+signatures of the generated Package indices is supported.
+
+Former working title of this program was mirrorer.
+.SH "GLOBAL OPTIONS"
+Options can be specified before the command. Each affects a different
+subset of commands and is ignored by other commands.
+.TP
+.B \-h \-\-help
+Displays a short list of options and commands with description.
+.TP
+.B \-v, \-V, \-\-verbose
+Be more verbose. Can be applied multiple times. One uppercase
+.B \-V
+counts as five lowercase
+.B \-v.
+.TP
+.B \-\-silent
+Be less verbose. Can be applied multiple times. One
+.B \-v
+and one
+.B \-s
+cancel each other out.
+.TP
+.B \-f, \-\-force
+This option is ignored, as it no longer exists.
+.TP
+.B \-b, \-\-basedir \fIbasedir\fP
+Sets the base\-dir all other default directories are relative to.
+If none is supplied and the
+.B REPREPRO_BASE_DIR
+environment variable is not set either, the current directory
+will be used.
+.TP
+.B \-\-outdir \fIoutdir\fP
+Sets the base\-dir of the repository to manage, i.e. where the
+.B pool/
+subdirectory resides. And in which the
+.B dists/
+directory is placed by default.
+If this starts with '\fB+b/\fP', it is relative to basedir.
+
+The default for this is \fIbasedir\fP.
+.TP
+.B \-\-confdir \fIconfdir\fP
+Sets the directory where the configuration is searched in.
+
+If this starts with '\fB+b/\fP', it is relative to basedir.
+
+If none is given, \fB+b/conf\fP (i.e. \fIbasedir\fP\fB/conf\fP) will be used.
+.TP
+.B \-\-distdir \fIdistdir\fP
+Sets the directory to generate index files relatively to. (i.e. things like
+Packages.gz, Sources.gz and Release.gpg)
+
+If this starts with '\fB+b/\fP', it is relative to basedir,
+if starting with '\fB+o/\fP' relative to outdir.
+
+If none is given, \fB+o/dists\fP (i.e. \fIoutdir\fP\fB/dists\fP) is used.
+
+.B Note:
+apt has
+.B dists
+hard-coded in it, so this is mostly only useful for testing or when your webserver
+pretends another directory structure than your physical layout.
+
+.B Warning:
+Beware when changing this forth and back between two values not ending
+in the same directory.
+Reprepro only looks if files it wants are there. If nothing of the content
+changed and there is a file it will not touch it, assuming it is the one it
+wrote last time, assuming any different \fB\-\-distdir\fP ended in the same
+directory.
+So either clean a directory before setting \fB\-\-distdir\fP to it or
+do an \fBexport\fP with the new one first to have a consistent state.
+.TP
+.B \-\-logdir \fIlogdir\fP
+The directory where files generated by the \fBLog:\fP directive are
+stored if they have no absolute path.
+
+If this starts with '\fB+b/\fP', it is relative to basedir,
+if starting with '\fB+o/\fP' relative to outdir,
+with '\fB+c/\fP' relative to confdir.
+
+If none is given, \fB+b/logs\fP (i.e. \fIbasedir\fP\fB/logs\fP) is used.
+.TP
+.B \-\-dbdir \fIdbdir\fP
+Sets the directory where reprepro keeps its databases.
+
+If this starts with '\fB+b/\fP', it is relative to basedir,
+if starting with '\fB+o/\fP' relative to outdir,
+with '\fB+c/\fP' relative to confdir.
+
+If none is given, \fB+b/db\fP (i.e. \fIbasedir\fP\fB/db\fP) is used.
+
+.B Note:
+This is permanent data, no cache. One has almost to regenerate the whole
+repository when this is lost.
+.TP
+.B \-\-listdir \fIlistdir\fP
+Sets the directory where it downloads indices to when importing
+from other repositories. This is temporary data and can be safely deleted
+when not in an update run.
+
+If this starts with '\fB+b/\fP', it is relative to basedir,
+if starting with '\fB+o/\fP' relative to outdir,
+with '\fB+c/\fP' relative to confdir.
+
+If none is given, \fB+b/lists\fP (i.e. \fIbasedir\fP\fB/lists\fP) is used.
+.TP
+.B \-\-morguedir \fImorguedir\fP
+Files deleted from the pool are stored into \fImorguedir\fP.
+
+If this starts with '\fB+b/\fP', it is relative to basedir,
+if starting with '\fB+o/\fP' relative to outdir,
+with '\fB+c/\fP' relative to confdir.
+
+If none is given, deleted files are just deleted.
+.TP
+.B \-\-methoddir \fImethoddir\fP
+Look in \fImethoddir\fP instead of
+.B /usr/lib/apt/methods
+for methods to call when importing from other repositories.
+.TP
+.B \-C, \-\-component \fIcomponents\fP
+Limit the specified command to this components only.
+This will force added packages to this components,
+limit removing packages from this components,
+only list packages in this components,
+and/or otherwise only look at packages in this components,
+depending on the command in question.
+
+Multiple components are specified by separating them with \fB|\fP,
+as in \fB\-C 'main|contrib'\fP.
+.TP
+.B \-A, \-\-architecture \fIarchitectures\fP
+Limit the specified command to this architectures only.
+(i.e. only list such packages,
+only remove packages from the specified architectures,
+or otherwise only look at/act on this architectures
+depending on the specific command).
+
+Multiple architectures are specified by separating them with \fB|\fP,
+as in \fB\-A 'sparc|i386'\fP.
+
+Note that architecture \fBall\fP packages can be included to each
+architecture but are then handled separately.
+Thus by using \fB\-A\fP in a specific way one can have different versions of
+an architecture \fBall\fP package in different architectures of the
+same distribution.
+.TP
+.B \-T, \-\-type \fRdsc|deb|udeb
+Limit the specified command to this packagetypes only.
+(i.e. only list such packages, only remove such packages, only include
+such packages, ...)
+.TP
+.B \-S, \-\-section \fIsection\fP
+Overrides the section of inclusions. (Also override possible override files)
+.TP
+.B \-P, \-\-priority \fIpriority\fP
+Overrides the priority of inclusions. (Also override possible override files)
+.TP
+.BR \-\-export= ( silent\-never | never | changed | lookedat | force )
+This option specify whether and how the high level actions
+(e.g. install, update, pull, delete)
+should export the index files of the distributions they work with.
+.TP
+.BR \-\-export=lookedat
+In this mode every distribution the action handled will be exported,
+unless there was an error possibly corrupting it.
+.br
+\fINote\fP that only missing files and files whose intended content changed
+between before and after the action will be written.
+To get a guaranteed current export, use the \fBexport\fP action.
+.br
+For backwards compatibility, \fBlookedat\fP is also available under the
+old name \fBnormal\fP.
+The name \fBnormal\fP is deprecated and will be removed in future versions.
+.TP
+.BR \-\-export=changed
+In this mode every distribution actually changed will be exported,
+unless there was an error possibly corrupting it.
+(i.e. if nothing changed, not even missing files will be created.)
+.br
+\fINote\fP that only missing files and files whose intended content changed
+between before and after the action will be written.
+To get a guaranteed current export, use the \fBexport\fP action.
+.TP
+.BR \-\-export=force
+Always export all distributions looked at, even if there was some
+error possibly bringing it into a inconsistent state.
+.TP
+.BR \-\-export=never
+No index files are exported. You will have to call \fBexport\fP later.
+.br
+\fINote\fP that you most likely additionally need the \fB\-\-keepunreferencedfiles\fP
+option, if you do not want some of the files pointed to by the untouched index
+files to vanish.
+.TP
+.BR \-\-export=silent-never
+Like never, but suppress most output about that.
+.TP
+.B \-\-ignore=\fIwhat\fP
+Ignore errors of type \fIwhat\fP. See the section \fBERROR IGNORING\fP
+for possible values.
+.TP
+.B \-\-nolistsdownload
+When running \fBupdate\fP, \fBcheckupdate\fP or \fBpredelete\fP do not download
+any Release or index files.
+This is hardly useful except when you just run one of those
+command for the same distributions.
+And even then reprepro is usually good in
+not downloading except \fBRelease\fP and \fBRelease.gpg\fP files again.
+.TP
+.B \-\-nothingiserror
+If nothing was done, return with exitcode 1 instead of the usual 0.
+
+Note that "nothing was done" means the primary purpose of the action
+in question.
+Auxiliary actions (opening and closing the database, exporting missing
+files with \-\-export=lookedat, ...) usually do not count.
+Also note that this is not very well tested.
+If you find an action that claims to have done something in some cases
+where you think it should not, please let me know.
+.TP
+.B \-\-keeptemporaries
+Do not delete temporary \fB.new\fP files when exporting a distribution
+fails.
+(reprepro first create \fB.new\fP files in the \fBdists\fP directory and
+only if everything is generated, all files are put into their final place
+at once.
+If this option is not specified and something fails, all are deleted
+to keep \fBdists\fP clean).
+.TP
+.B \-\-keepunreferencedfiles
+Do not delete files that are no longer used because the package they
+are from is deleted/replaced with a newer version from the last distribution
+it was in.
+.TP
+.B \-\-keepunusednewfiles
+The include, includedsc, includedeb and processincoming by default delete
+any file they added to the pool that is not marked used at the end of the
+operation.
+While this keeps the pool clean and allows changing before trying to add again,
+this needs copying and checksum calculation every time one tries to add a file.
+.TP
+.B \-\-keepdirectories
+Do not try to rmdir parent directories after files or directories
+have been removed from them.
+(Do this if your directories have special permissions you want keep,
+do not want to be pestered with warnings about errors to remove them,
+or have a buggy rmdir call deleting non-empty directories.)
+.TP
+.B \-\-ask\-passphrase
+Ask for passphrases when signing things and one is needed. This is a quick
+and dirty and unsafe implementation using the obsolete \fBgetpass(3)\fP
+function with the description gpgme is supplying.
+So the prompt will look quite funny and support for passphrases with
+more than 8 characters depend on your libc.
+Use of this option is not recommended. Use gpg-agent with pinentry instead.
+
+(With current versions of gnupg you need to set \fBpinentry-mode loopback\fP
+in your .gnupg/gpg.conf file to use \fB\-\-ask\-passphrase\fP.
+Without that option gnupg uses the much safer and recommended pinentry instead).
+.TP
+.B \-\-noskipold
+When updating do not skip targets where no new index files and no files
+marked as already processed are available.
+
+If you changed a script to preprocess downloaded index files or
+changed a Listfilter, you most likely want to call reprepro with \-\-noskipold.
+.TP
+.B \-\-waitforlock \fIcount
+If there is a lockfile indicating another instance of reprepro is currently
+using the database, retry \fIcount\fP times after waiting for 10 seconds
+each time.
+The default is 0 and means to error out instantly.
+.TP
+.B \-\-spacecheck full\fR|\fPnone
+The default is \fBfull\fR:
+.br
+In the update commands, check for every to be downloaded file which filesystem
+it is on and how much space is left.
+.br
+To disable this behaviour, use \fBnone\fP.
+.TP
+.BI \-\-dbsafetymargin " bytes-count"
+If checking for free space, reserve \fIbyte-count\fP bytes on the filesystem
+containing the \fBdb/\fP directory.
+The default is 104857600 (i.e. 100MB), which is quite large.
+But as there is no way to know in advance how large the databases will
+grow and libdb is extremely touchy in that regard, lower only when you know
+what you do.
+.TP
+.BI \-\-safetymargin " bytes-count"
+If checking for free space, reserve \fIbyte-count\fP bytes on filesystems
+not containing the \fBdb/\fP directory.
+The default is 1048576 (i.e. 1MB).
+.TP
+.B \-\-noguessgpgtty
+Don't set the environment variable
+.BR GPG_TTY ,
+even when it is not set, stdin is terminal and
+.B /proc/self/fd/0
+is a readable symbolic link.
+.TP
+.B \-\-gnupghome
+Set the
+.B GNUPGHOME
+evnironment variable to the given directory as argument to this option.
+And your gpg will most likely use the content of this variable
+instead of "~/.gnupg".
+Take a look at
+.BR gpg (1)
+to be sure.
+This option in the command line is usually not very useful, as it is possible
+to set the environment variable directly.
+Its main reason for existence is that it can be used in \fIconf\fP\fB/options\fP.
+.TP
+.BI \-\-gunzip " gz-uncompressor"
+While reprepro links against \fBlibz\fP, it will look for the program given
+with this option (or \fBgunzip\fP if not given) and use that when uncompressing
+index files while downloading from remote repositories.
+(So that downloading and uncompression can happen at the same time).
+If the program is not found or is \fBNONE\fP (all-uppercase) then uncompressing
+will always be done using the built in uncompression method.
+The program has to accept the compressed file as stdin and write
+the uncompressed file into stdout.
+.TP
+.BI \-\-bunzip2 " bz2-uncompressor"
+When uncompressing downloaded index files or if not linked against \fBlibbz2\fP
+reprepro will use this program to uncompress \fB.bz2\fP files.
+The default value is \fBbunzip2\fP.
+If the program is not found or is \fBNONE\fP (all-uppercase) then uncompressing
+will always be done using the built in uncompression method or not be possible
+if not linked against \fBlibbz2\fP.
+The program has to accept the compressed file as stdin and write
+the uncompressed file into stdout.
+.TP
+.BI \-\-unlzma " lzma-uncompressor"
+When uncompressing downloaded index files or if not linked against \fBliblzma\fP
+reprepro will use this program to uncompress \fB.lzma\fP files.
+The default value is \fBunlzma\fP.
+If the program is not found or is \fBNONE\fP (all-uppercase)
+then uncompressing lzma files will always be done using
+the built in uncompression method
+or not be possible if not linked against \fBliblzma\fP.
+The program has to accept the compressed file as stdin and write
+the uncompressed file into stdout.
+.TP
+.BI \-\-unxz " xz-uncompressor"
+When uncompressing downloaded index files or if not linked against \fBliblzma\fP
+reprepro will use this program to uncompress \fB.xz\fP files.
+The default value is \fBunxz\fP.
+If the program is not found or is \fBNONE\fP (all-uppercase)
+then uncompressing xz files will always be done using
+the built in uncompression method
+or not be possible if not linked against \fBliblzma\fP.
+The program has to accept the compressed file as stdin and write
+the uncompressed file into stdout.
+.TP
+.BI \-\-lunzip " lzip-uncompressor"
+When trying to uncompress or read \fPlzip\fP compressed files, this program
+will be used.
+The default value is \fBlunzip\fP.
+If the program is not found or is \fBNONE\fP (all-uppercase) then uncompressing
+lz files will not be possible.
+The program has to accept the compressed file as stdin and write
+the uncompressed file into stdout.
+Note that .lz support is \fBDEPRECATED\fP and will be removed in the future.
+.TP
+.BI \-\-list\-max " count"
+Limits the output of \fBlist\fP, \fBlistmatched\fP and \fBlistfilter\fP to the first \fIcount\fP
+results.
+The default is 0, which means unlimited.
+.TP
+.BI \-\-list\-skip " count"
+Omitts the first \fIcount\fP results from the output of
+\fBlist\fP, \fBlistmatched\fP and \fBlistfilter\fP.
+.TP
+.BI \-\-list\-format " format"
+Set the output format of \fBlist\fP, \fBlistmatched\fP and \fBlistfilter\fP commands.
+The format is similar to dpkg\-query's \fB\-\-showformat\fP:
+fields are specified as
+.BI ${ fieldname }
+or
+.BI ${ fieldname ; length }\fR.\fP
+Zero length or no length means unlimited.
+Positive numbers mean fill with spaces right, negative fill with spaces left.
+
+.BR \[rs]n ", " \[rs]r ", " \[rs]t ", " \[rs]0
+are new-line, carriage-return, tabulator and zero-byte.
+Backslash (\fB\[rs]\fP) can be used to escape every non-letter-or-digit.
+
+The special field names
+.BR $identifier ", " $architecture ", " $component ", " $type ", " $codename
+denote where the package was found.
+
+The special field names
+.BR $source " and " $sourceversion
+denote the source and source version a package belongs to.
+(i.e.
+.B ${$source}
+will either be the same as
+.B ${source}
+(without a possible version in parentheses at the end)
+or the same as
+.BR ${package} .
+
+The special field names
+.BR $basename ", " $filekey " and " $fullfilename
+denote the first package file part of this entry
+(i.e. usually the .deb, .udeb or .dsc file)
+as basename, as filekey (filename relative to the outdir)
+and the full filename with outdir prepended
+(i.e. as relative or absolute as your
+outdir (or basedir if you did not set outdir) is).
+
+When \fB\-\-list\-format\fP is not given or \fBNONE\fP, then the default
+is equivalent to
+.br
+.BR "${$identifier} ${package} ${version}\[rs]n" .
+
+Escaping digits or letters not in above list,
+using dollars not escaped outside specified constructs,
+or any field names not listed as special and not consisting entirely out of
+letters, digits and minus signs have undefined behaviour
+and might change meaning without any further notice.
+
+If you give this option on the command line,
+don't forget that $ is also interpreted by your shell.
+So you have to properly escape it.
+For example by putting the whole argument to \-\-list\-format in single quotes.
+.TP
+.B \-\-show\-percent
+When downloading packages, show each completed percent of completed package
+downloads together with the size of completely downloaded packages.
+(Repeating this option increases the frequency of this output).
+.TP
+.B \-\-onlysmalldeletes
+The pull and update commands will skip every distribution in which one
+target loses more than 20% of its packages (and at least 10).
+
+Using this option (or putting it in the options config file) can
+avoid removing large quantities of data but means you might often
+give
+.B \-\-noonlysmalldeletes
+to override it.
+.TP
+.B \-\-restrict \fIsrc\fP\fR[\fP=\fIversion\fP\fR|\fP:\fItype\fP\fR]\fP
+Restrict a \fBpull\fP or \fBupdate\fP to only act on packages belonging
+to source-package \fIsrc\fP.
+Any other package will not be updated (unless it matches a \fB\-\-restrict\-bin\fP).
+Only packages that would otherwise be updated or are at least marked with \fBhold\fP
+in a \fBFilterList\fP or \fBFilerSrcList\fP will be updated.
+
+The action can be restricted to a source version using a equal sign or
+changed to another type (see FilterList) using a colon.
+
+This option can be given multiple times to list multiple packages, but each
+package may only be named once (even when there are different versions or types).
+.TP
+.B \-\-restrict\-binary \fIname\fP\fR[\fP=\fIversion\fP\fR|\fP:\fItype\fP\fR]\fP
+Like \fB\-\-restrict\fP but restrict to binary packages (\fB.deb\fP and \fB.udeb\fP).
+Source packages are not upgraded unless they appear in a \fB\-\-restrict\fP.
+.TP
+.B \-\-restrict\-file \fIfilename\fP
+Like \fB\-\-restrict\fP but read a whole file in the \fBFilterSrcList\fP format.
+.TP
+.B \-\-restrict\-file\-bin \fIfilename\fP
+Like \fB\-\-restrict\-bin\fP but read a whole file in the \fBFilterList\fP format.
+.TP
+.B \-\-endhook \fIhookscript\fP
+
+Run the specified \fIhookscript\fP once reprepro exits.
+It will get the usual \fBREPREPRO_\fP* environment variables set (or unset)
+and additionally a variable \fBREPREPRO_EXIT_CODE\fP that is the exit code
+with which reprepro would have exited (the hook is always called once the
+initial parsing of global options and the command name is done, no matter
+if reprepro did anything or not).
+Reprepro will return to the calling process with the exitcode of this script.
+Reprepro has closed all its databases and removed all its locks,
+so you can run reprepro again in this script
+(unless someone else did so in the same repository before, of course).
+
+The only advantage over running that command always directly after reprepro
+is that you can some environment variables set and cannot so easily forget
+it if this option is in conf/options.
+
+The script is supposed to be located relative to \fIconfdir\fP, unless its
+name starts with \fB/\fP, \fB./\fP, \fB+b/\fP, \fB+o/\fP, or \fB+c/\fP
+and the name may not start (except in the cases given before) with a \fB+\fP.
+
+An example script looks like: \fB
+ #!/bin/sh
+
+ if [ "$REPREPRO_EXIT_CODE" \-ne 0 ] ; then
+ exit "$REPREPRO_EXIT_CODE"
+ fi
+
+ echo "congratulations, reprepro with arguments: $*"
+ echo "seems to have run successfully. REPREPRO_ part of the environment is:"
+ set | grep ^REPREPRO_
+
+ exit 0
+ \fP
+.TP
+.B \-\-outhook \fIhookscript\fP
+\fIhookscript\fP is called with a \fB.outlog\fP file as argument (located
+in \fIlogdir\fP) containing a description of all changes made to \fIoutdir\fP.
+
+The script is supposed to be located relative to \fIconfdir\fP, unless its
+name starts with \fB/\fP, \fB./\fP, \fB+b/\fP, \fB+o/\fP, or \fB+c/\fP
+and the name may not start (except in the cases given before) with a \fB+\fP.
+
+For a format of the \fB.outlog\fP files generated for this script see the
+\fBmanual.html\fP shipped with reprepro.
+.SH COMMANDS
+.TP
+.BR export " [ " \fIcodenames\fP " ]"
+Generate all index files for the specified distributions.
+
+This regenerates all files unconditionally.
+It is only useful if you want to be sure \fBdists\fP is up to date,
+you called some other actions with \fB\-\-export=never\fP before or
+you want to create an initial empty but fully equipped
+.BI dists/ codename

+
+It will not create links, when multiple of the given codenames

+.TP
+.B list \fIcodename\fP \fR[\fP \fIpackagename\fP \fR]\fP
+List all packages (source and binary, except when

+or
+.B \-A
+is given) with the given name in all components (except when
+.B \-C
+is given) and architectures (except when
+.B \-A
+is given) of the specified distribution.
+If no package name is given, list everything.

+\fB\-\-list\-skip\fP.
+.TP
+.B listmatched \fIcodename\fP \fIglob\fP
+as list, but does not list a single package, but all packages
+matching the given shell-like \fIglob\fP.
+(i.e. \fB*\fP, \fB?\fP and \fB[\fP\fIchars\fP\fB]\fP are allowed).
+
+Examples:
+
+.B reprepro \-b . listmatched test2 'linux\-*'
+lists all packages starting with \fBlinux\-\fP.
+
+.TP
+.B listfilter \fIcodename\fP \fIcondition\fP
+as list, but does not list a single package, but all packages
+matching the given condition.
+
+The format of the formulas is those of the dependency lines in
+Debian packages' control files with some extras.
+That means a formula consists of names of fields with a possible
+condition for its content in parentheses.
+These atoms can be combined with
+an exclamation mark '!' (meaning not),
+a pipe symbol '|' (meaning or) and
+a comma ',' (meaning and).
+Additionally parentheses can be used to change binding
+(otherwise '!' binds more than '|' than ',').
+
+The values given in the search expression are directly alphabetically
+compared to the headers in the respective index file.
+That means that each part \fIFieldname\fP\fB (\fP\fIcmp\fP\fB \fP\fIvalue\fP\fB)\fP
+of the formula will be true for exactly those package that have
+in the \fBPackage\fP or \fBSources\fP file a line starting with \fIfieldname\fP
+and a value is alphabetically \fIcmp\fP to \fIvalue\fP.
+
+Additionally since reprepro 3.11.0, '\fB%\fP' can be used as comparison operator,
+denoting matching a name with shell like wildcard
+(with '\fB*\fP', '\fB?\fP' and '\fB[\fP..\fB]\fP').
+
+The special field names starting with '\fB$\fP' have special meaning
+(available since 3.11.1):
+
+.B $Version
+
+The version of the package, comparison is not alphabetically, but as
+Debian version strings.
+
+.B $Source
+
+The source name of the package.
+
+.B $SourceVersion
+
+The source version of the package.
+
+.B $Architecture
+
+The architecture the package is in (listfilter) or to be put into.
+
+.B $Component
+
+The component the package is in (listfilter) or to be put into.
+
+.B $Packagetype
+
+The packagetype of the package.
+
+Examples:
+
+.B reprepro \-b . listfilter test2 'Section (== admin)'
+will list all packages in distribution test2 with a Section field and the value
+of that field being \fBadmin\fP.
+
+.B reprepro \-b . \-T deb listfilter test2 'Source (== \fIblub\fP) | ( !Source , Package (== \fIblub\fP) )'
+will find all .deb Packages with either a Source field blub or
+no Source field and a Package field blub.
+(That means all package generated by a source package \fIblub\fP,
+except those also specifying a version number with its Source).
+
+.B reprepro \-b . \-T deb listfilter test2 '$Source (==\fIblub\fP)'
+is the better way to do this (but only available since 3.11.1).
+
+.B reprepro \-b . listfilter test2 '$PackageType (==deb), $Source (==\fIblub\fP)'
+is another (less efficient) way.
+
+.B reprepro \-b . listfilter test2 'Package (% linux\-*\-2.6*)'
+lists all packages with names starting with \fBlinux\-\fP and later
+having an \fB\-2.6\fP.
+.TP
+.B ls \fIpackage-name\fP
+List the versions of the specified package in all distributions.
+.TP

+.TP
+.B remove \fIcodename\fP \fIpackage-names\fP\fR[\fP=\fIversion\fP\fR]\fP \fI...\fP
+Delete packages in the specified distribution,
+that have package name listed as argument.
+Package versions must be specified by appending '\fB=\fP' and the
+version to the name (without spaces). When no version is specified, the latest
+package version is removed.
+
+Note that like any other operation removing or replacing a package,
+the old package's files are unreferenced and thus may be automatically
+deleted if this was their last reference and no \fB\-\-keepunreferencedfiles\fP
+specified.
+.TP

+(Limited to those with source version \fIversion\fP if specified).
+
+If package tracking is activated, it will use that information to find the

+.TP
+.B removesrcs \fIcodename\fP \fIsource-name\fP\fR[\fP=\fIversion\fP\fR]\fP \fI...\fP

+This will determine which packages a \fBupdate\fP would delete or

+.TP
+.B cleanlists
+Delete all files in \fIlistdir\fP (default \fIbasedir\fP\fB/lists\fP) that do not

+.B _listconfidentifiers \fIidentifier\fP \fR[\fP \fIdistributions...\fP \fR]\fP
+Print - one per line - all identifiers of subdatabases as derived from the
+configuration.
+If a list of distributions is given, only identifiers of those are printed.
+
+.TP
+.B _listdbidentifiers \fIidentifier\fP \fR[\fP \fIdistributions...\fP \fR]\fP
+Print - one per line - all identifiers of subdatabases in the current
+database.
+This will be a subset of the ones printed by \fB_listconfidentifiers\fP or
+most commands but \fBclearvanished\fP will refuse to run, and depending
+on the database compatibility version, will include all those if reprepro
+was run since the config was last changed.
+
+.SH "CONFIG FILES"
+.B reprepo
+uses three config files, which are searched in
+the directory specified with
+.B \-\-confdir
+or in the
+.B conf/
+subdirectory of the \fIbasedir\fP.
+
+If a file
+.B options
+exists, it is parsed line by line.
+Each line can be the long
+name of a command line option (without the \-\-)
+plus an argument, where possible.
+Those are handled as if they were command line options given before
+(and thus lower priority than) any other command line option.
+(and also lower priority than any environment variable).
+
+To allow command line options to override options file options,
+most boolean options also have a corresponding form starting with \fB\-\-no\fP.
+
+(The only exception is when the path to look for config files
+changes, the options file will only opened once and of course
+before any options within the options file are parsed.)
+
+The file
+.B distributions
+is always needed and describes what distributions
+to manage, while
+.B updates
+is only needed when syncing with external repositories and
+.B pulls
+is only needed when syncing with repositories in the same reprepro database.
+
+The last three are in the format control files in Debian are in,
+i.e. paragraphs separated by empty lines consisting of
+fields. Each field consists of a fieldname, followed
+by a colon, possible whitespace and the data. A field
+ends with a newline not followed by a space or tab.
+
+Lines starting with # as first character are ignored,
+while in other lines the # character and
+everything after it till the newline character are ignored.
+
+A paragraph can also consist of only a single field
+.RB \(dq !include: \(dq
+which causes the named file (relative to confdir unless starting
+with
+.BR ~/ ", " +b/ ", " +c/ " or " / " )"
+to be read as if it was found at this place.
+
+Each of the three files or a file included as described above
+can also be a directory, in which case all files it contains
+with a filename ending in
+.B .conf
+and not starting with
+.B .
+are read.
+.SS conf/distributions
+.TP
+.B Codename
+This required field is the unique identifier of a distribution
+and used as directory name within
+.B dists/
+It is also copied into the Release files.
+
+Note that this name is not supposed to change.
+You most likely \fBnever ever\fP want a name like \fBtesting\fP
+or \fBstable\fP here (those are suite names and supposed to point
+to another distribution later).
+.TP
+.B Suite
+This optional field is simply copied into the
+Release files. In Debian it contains names like
+stable, testing or unstable. To create symlinks
+from the Suite to the Codename, use the
+\fBcreatesymlinks\fP command of reprepro.
+.TP
+.B FakeComponentPrefix
+If this field is present,
+its argument is added - separated by a slash - before every
+Component written to the main Release file
+(unless the component already starts with it),
+and removed from the end of the Codename and Suite fields in that file.
+Also if a component starts with it, its directory in the dists dir
+is shortened by this.
+.br
+So \fB
+
+ Codename: bla/updates
+ Suite: foo/updates
+ FakeComponentPrefix: updates
+ Components: main bad\fP
+
+will create a Release file with \fB
+
+ Codename: bla
+ Suite: foo
+ Components: updates/main updates/bad\fP
+
+in it, but otherwise nothing is changed, while\fB
+
+ Codename: bla/updates
+ Suite: foo/updates
+ FakeComponentPrefix: updates
+ Components: updates/main updates/bad\fP
+
+will also create a Release file with \fB
+
+ Codename: bla
+ Suite: foo
+ Components: updates/main updates/bad\fP
+
+but the packages will actually be in the components
+\fBupdates/main\fP and \fBupdates/bad\fP,
+most likely causing the same file using duplicate storage space.
+
+This makes the distribution look more like Debian's security archive,
+thus work around problems with apt's workarounds for that.
+.TP
+.B AlsoAcceptFor
+A list of distribution names.
+When a \fB.changes\fP file is told to be included
+into this distribution with the \fBinclude\fP command
+and the distribution header of that file is neither
+the codename, nor the suite name, nor any name from the
+list, a \fBwrongdistribution\fP error is generated.
+The \fBprocess_incoming\fP command will also use this field,
+see the description of \fBAllow\fP and \fBDefault\fP
+from the \fBconf/incoming\fP file for more information.
+.TP
+.B Version
+This optional field is simply copied into the
+Release files.
+.TP
+.B Origin
+This optional field is simply copied into the
+Release files.
+.TP
+.B Label
+This optional field is simply copied into the
+Release files.
+.TP
+.B NotAutomatic
+This optional field is simply copied into the
+Release files.
+(The value is handled as an arbitrary string,
+though anything but \fByes\fP does not make much
+sense right now.)
+.TP
+.B ButAutomaticUpgrades
+This optional field is simply copied into the
+Release files.
+(The value is handled as an arbitrary string,
+though anything but \fByes\fP does not make much
+sense right now.)
+.TP
+.B Description
+This optional field is simply copied into the
+Release files.
+.TP
+.B Architectures
+This required field lists the binary architectures within
+this distribution and if it contains
+.B source
+(i.e. if there is an item
+.B source
+in this line this Distribution has source. All other items
+specify things to be put after "binary\-" to form directory names
+and be checked against "Architecture:" fields.)
+
+This will also be copied into the Release files. (With exception
+of the
+.B source
+item, which will not occur in the topmost Release file whether
+it is present here or not)
+.TP
+.B Components
+This required field lists the component of a
+distribution. See
+.B GUESSING
+for rules which component packages are included into
+by default. This will also be copied into the Release files.
+.TP
+.B DDebComponents
+List of components containing .ddebs.
+.TP
+.B UDebComponents
+Components with a debian\-installer subhierarchy containing .udebs.
+(E.g. simply "main")
+.TP
+.B Update
+When this field is present, it describes which update rules are used
+for this distribution. There also can be a magic rule minus ("\-"),
+see below.
+.TP
+.B Pull
+When this field is present, it describes which pull rules are used
+for this distribution.
+Pull rules are like Update rules,
+but get their stuff from other distributions and not from external sources.
+See the description for \fBconf/pulls\fP.
+.TP
+.B SignWith
+When this field is present, a Release.gpg file will be generated.
+If the value is "yes" or "default", the default key of gpg is used.
+If the field starts with an exclamation mark ("!"), the given script
+is executed to do the signing.
+Otherwise the value will be given to libgpgme to determine to key to
+use.
+
+If there are problems with signing, you can try
+.br
+.B gpg \-\-list\-secret\-keys \fIvalue\fP
+.br
+to see how gpg could interpret the value.
+If that command does not list any keys or multiple ones,
+try to find some other value (like the keyid),
+that gpg can more easily associate with a unique key.
+
+If this key has a passphrase, you need to use gpg\-agent
+or the insecure option \fB\-\-ask\-passphrase\fP.
+
+A '\fB!\fP' hook script is looked for in the confdir,
+unless it starts with
+.BR ~/ ", " ./ ", " +b/ ", " +o/ ", " +c/ " or " / " ."
+Is gets three command line arguments: The filename to sign,
+an empty argument or the filename to create with an inline
+signature (i.e. InRelease) and
+an empty argument or the filename to create an detached signature
+(i.e. Release.gpg).
+The script may generate no Release.gpg file if it choses to
+(then the repository will look like unsigned for older clients),
+but generating empty files is not allowed.
+Reprepro waits for the script to finish and will abort the exporting
+of the distribution this signing is part of unless the scripts
+returns normally with exit code 0.
+Using a space after ! is recommended to avoid incompatibilities
+with possible future extensions.
+.TP
+.B DebOverride
+When this field is present, it describes the override file used
+when including .deb files.
+.TP
+.B UDebOverride
+When this field is present, it describes the override file used
+when including .udeb files.
+.TP
+.B DscOverride
+When this field is present, it describes the override file used
+when including .dsc files.
+.TP
+.B DebIndices\fR, \fBUDebIndices\fR, \fBDscIndices
+Choose what kind of Index files to export. The first
+part describes what the Index file shall be called.
+The second argument determines the name of a Release
+file to generate or not to generate if missing.
+Then at least one of "\fB.\fP", "\fB.gz\fP", "\fB.xz\fP" or "\fB.bz2\fP"
+specifying whether to generate uncompressed output, gzipped
+output, bzip2ed output or any combination.
+(bzip2 is only available when compiled with bzip2 support,
+so it might not be available when you compiled it on your
+own, same for xz and liblzma).
+If an argument not starting with dot follows,
+it will be executed after all index files are generated.
+(See the examples for what argument this gets).
+The default is:
+.br
+DebIndices: Packages Release . .gz
+.br
+UDebIndices: Packages . .gz
+.br
+DscIndices: Sources Release .gz
+.TP
+.B ExportOptions
+Options to modify how and if exporting is done:
+.br
+.B noexport
+Never export this distribution.
+That means there will be no directory below \fBdists/\fP generated and the distribution is only useful to copy packages to other distributions.
+.br
+.B keepunknown
+Ignore unknown files and directories in the exported directory.
+This is currently the only available option and the default, but might change in the future, so it can already be requested explicitly.
+.TP
+.B Contents
+Enable the creation of Contents files listing all the files
+within the binary packages of a distribution.
+(Which is quite slow, you have been warned).
+
+In earlier versions, the first argument was a rate at which
+to extract file lists.
+As this did not work and was no longer easily possible after
+some factorisation, this is no longer supported.
+
+The arguments of this field is a space separated list of options.
+If there is a \fBudebs\fP keyword, \fB.udeb\fPs are also listed
+(in a file called \fBuContents\-\fP\fIarchitecture\fP.)
+If there is a \fBnodebs\fP keyword, \fB.deb\fPs are not listed.
+(Only useful together with \fBudebs\fP)
+If there is at least one of the keywords
+\fB.\fP, \fB.gz\fP, \fB\.xz\fP and/or \fB.bz2\fP,
+the Contents files are written uncompressed, gzipped and/or bzip2ed instead
+of only gzipped.
+
+If there is a \fBpercomponent\fP then one Contents\-\fIarch\fP file
+per component is created.
+If there is a \fBallcomponents\fP then one global Contents\-\fIarch\fP
+file is generated.
+If both are given, both are created.
+If none of both is specified then \fBpercomponent\fP is taken
+as default (earlier versions had other defaults).
+
+The switches \fBcompatsymlink\fP or \fBnocompatsymlink\fP
+(only possible if \fBallcomponents\fP was not specified explicitly)
+control whether a compatibility symlink is created so old versions
+of apt\-file looking for the component independent filenames at
+least see the contents of the first component.
+
+Unless \fBallcomponents\fP is given, \fBcompatsymlinks\fP
+currently is the default, but that will change
+in some future (current estimate: after wheezy was released)
+
+.TP
+.B ContentsArchitectures
+Limit generation of Contents files to the architectures given.
+If this field is not there, all architectures are processed.
+An empty field means no architectures are processed, thus not
+very useful.
+.TP
+.B ContentsComponents
+Limit what components are processed for the \fBContents\-\fP\fIarch\fP
+files to the components given.
+If this field is not there, all components are processed.
+An empty field is equivalent to specify \fBnodebs\fP in the
+\fBContents\fP field, while a non-empty field overrides a
+\fBnodebs\fP there.
+.TP
+.B ContentsUComponents
+Limit what components are processed for the uContents files to
+the components given.
+If this field is not there and there is the \fBudebs\fP keyword
+in the Contents field, all .udebs of all components are put
+in the \fBuContents.\fP\fIarch\fP files.
+If this field is not there and there is no \fBudebs\fP keyword
+in the Contents field, no \fBuContents\-\fP\fIarch\fP files are
+generated at all.
+A non-empty fields implies generation of \fBuContents\-\fP\fIarch\fP
+files (just like the \fBudebs\fP keyword in the Contents field),
+while an empty one causes no \fBuContents\-\fP\fIarch\fP files to
+be generated.
+.TP
+.B Uploaders
+Specifies a file (relative to confdir if not starting with
+.BR ~/ ", " +b/ ", " +c/ " or " / " )"
+to specify who is allowed to upload packages. Without this there are no
+limits, and this file can be ignored via \fB\-\-ignore=uploaders\fP.
+See the section \fBUPLOADERS FILES\fP below.
+.TP
+.B Tracking
+Enable the (experimental) tracking of source packages.
+The argument list needs to contain exactly one of the following:
+.br
+.B keep
+Keeps all files of a given source package, until that
+is deleted explicitly via \fBremovetrack\fP. This is
+currently the only possibility to keep older packages
+around when all indices contain newer files.
+.br
+.B all
+Keep all files belonging to a given source package until
+the last file of it is no longer used within that
+distribution.
+.br
+.B minimal
+Remove files no longer included in the tracked distribution.
+(Remove changes, logs and includebyhand files once no file is
+in any part of the distribution).
+.br
+And any number of the following (or none):
+.br
+.B includechanges
+Add the .changes file to the tracked files of a source package.
+Thus it is also put into the pool.
+.br
+.B includebyhand
+Add \fBbyhand\fP and \fBraw\-\fP\fI*\fP files to the tracked
+files and thus in the pool.
+.br
+.B includebuildinfos
+Add buildinfo files to the tracked files and thus in the pool.
+.br
+.B includelogs
+Add log files to the tracked files and thus in the pool.
+(Not that putting log files in changes files is a reprepro
+extension not found in normal changes files)
+.br
+.B embargoalls
+Not yet implemented.
+.br
+.B keepsources
+Even when using minimal mode, do not remove source files
+until no file is needed any more.
+.br
+.B needsources
+Not yet implemented.
+.TP
+.B Limit
+Limit the number of versions of a package per distribution, architecture,
+component, and type. The limit must be a number. If the number is positive,
+all old package version that exceed these limit will be removed or archived
+(see
+.B Archive
+option), when a new package version is added. If the number is zero or negative,
+all package version will be kept. By default only one package version will be
+kept.
+.TP
+.B Archive
+Specify a codename which must be declared before (to avoid loops). When packages
+exceed the version count limit (specified in \fBLimit\fR), these packages will
+be moved to the specified distribution instead of being removed.
+.TP
+.B Log
+Specify a file to log additions and removals of this distribution
+into and/or external scripts to call when something is added or
+removed.
+The rest of the \fBLog:\fP line is the filename,
+every following line (as usual, have to begin with a single space)
+the name of a script to call.
+The name of the script may be preceded with options of the
+form \fB\-\-type=\fP(\fBdsc\fP|\fBdeb\fP|\fBudeb\fP),
+\fB\-\-architecture=\fP\fIname\fP or
+\fB\-\-component=\fP\fIname\fP to only call the script for some
+parts of the distribution.
+An script with argument \fB\-\-changes\fP is called when a \fB.changes\fP
+file was accepted by \fBinclude\fP or \fBprocessincoming\fP (and with other
+arguments).
+Both type of scripts can have a \fB\-\-via=\fP\fIcommand\fP specified,
+in which case it is only called when caused by reprepro command \fIcommand\fP.
+
+For information how it is called and some examples take a look
+at manual.html in reprepro's source or
+.B /usr/share/doc/reprepro/
+
+If the filename for the log files does not start with a slash,
+it is relative to the directory specified with \fB\-\-logdir\fP,
+the scripts are relative to \fB\-\-confdir\fP unless starting with
+.BR ~/ ", " +b/ ", " +c/ " or " / .
+.TP
+.B ValidFor
+If this field exists, an Valid\-Until field is put into generated
+.B Release
+files for this distribution with an date as much in the future as the
+argument specifies.
+
+The argument has to be an number followed by one of the units
+.BR d ", " m " or " y ,
+where \fBd\fP means days, \fBm\fP means 31 days and \fBy\fP means
+365 days.
+So
+.B ValidFor: 1m 11 d
+causes the generation of a
+.B Valid\-Until:
+header in Release files that points 42 days into the future.
+.TP
+.B ReadOnly
+Disallow all modifications of this distribution or its directory
+in \fBdists/\fP\fIcodename\fP (with the exception of snapshot subdirectories).
+.TP
+.B ByHandHooks
+This species hooks to call for handling byhand/raw files by processincoming
+(and in future versions perhaps by include).
+
+Each line consists out of 4 arguments:
+A glob pattern for the section
+(classically \fBbyhand\fP, though Ubuntu uses \fBraw\-\fP*),
+a glob pattern for the priority (not usually used),
+and a glob pattern for the filename.
+
+The 4th argument is the script to be called when all of the above match.
+It gets 5 arguments: the codename of the distribution,
+the section (usually \fBbyhand\fP),
+the priority (usually only \fB\-\fP),
+the filename in the changes file and
+the full filename (with processincoming in the secure TempDir).
+.TP
+.B Signed\-By
+This optional field is simply copied into the Release files.
+It is used to tell apt which keys to trust for this Release
+in the future.
+(see SignWith for how to tell reprepro whether and how to sign).
+.SS conf/updates
+.TP
+.B Name
+The name of this update\-upstream as it can be used in the
+.B Update
+field in conf/distributions.
+.TP
+.B Method
+An URI as one could also give it apt, e.g.
+.I http://ftp.debian.de/debian
+which is simply given to the corresponding
+.B apt\-get
+method. (So either
+.B apt\-get has to be installed, or you have to point with
+.B \-\-methoddir
+to a place where such methods are found.
+.TP
+.B Fallback
+(Still experimental:) A fallback URI, where all files are
+tried that failed the first one. They are given to the
+same method as the previous URI (e.g. both http://), and
+the fallback-server must have everything at the same place.
+No recalculation is done, but single files are just retried from
+this location.
+.TP
+.B Config
+This can contain any number of lines, each in the format
+.B apt\-get \-\-option
+would expect. (Multiple lines \(hy as always \(hy marked with
+leading spaces).
+.P
+For example: Config: Acquire::Http::Proxy=http://proxy.yours.org:8080
+.TP
+.B From
+The name of another update rule this rules derives from.
+The rule containing the \fBFrom\fP may not contain
+.BR Method ", " Fallback " or " Config "."
+All other fields are used from the rule referenced in \fBFrom\fP, unless
+found in this containing the \fBFrom\fP.
+The rule referenced in \fBFrom\fP may itself contain a \fBFrom\fP.
+Reprepro will only assume two remote index files are the same,
+if both get their \fBMethod\fP information from the same rule.
+.TP
+.B Suite
+The suite to update from. If this is not present, the codename
+of the distribution using this one is used. Also "*/whatever"
+is replaced by "<codename>/whatever"
+.TP
+.B Components
+The components to update. Each item can be either the name
+of a component or a pair of a upstream component and a local
+component separated with ">". (e.g. "main>all contrib>all non\-free>notall")
+
+If this field is not there, all components from the distribution
+to update are tried.
+
+An empty field means no source or .deb packages are updated by this rule,
+but only .udeb packages, if there are any.
+
+A rule might list components not available in all distributions
+using this rule. In this case unknown components are silently
+ignored.
+(Unless you start reprepro with the \fB\-\-fast\fP option,
+it will warn about components unusable in all distributions using
+that rule. As exceptions, unusable components called \fBnone\fP
+are never warned about, for compatibility with versions prior to
+3.0.0 where and empty field had a different meaning.)
+.TP
+.B Architectures
+The architectures to update. If omitted all from the distribution
+to update from. (As with components, you can use ">" to download
+from one architecture and add into another one. (This only determine
+in which Package list they land, it neither overwrites the Architecture
+line in its description, nor the one in the filename determined from this
+one. In other words, it is no really useful without additional filtering))
+.TP
+.B UDebComponents
+Like
+.B Components
+but for the udebs.
+.TP
+.B VerifyRelease
+Download the
+.B Release.gpg
+file and check if it is a signature of the
+.B Releasefile
+with the key given here. (In the Format as
+"gpg \-\-with\-colons \-\-list\-key" prints it, i.e. the last
+16 hex digits of the fingerprint) Multiple keys can be specified
+by separating them with a "\fB|\fP" sign. Then finding a signature
+from one of the will suffice.
+To allow revoked or expired keys, add a "\fB!\fP" behind a key.
+(but to accept such signatures, the appropriate \fB\-\-ignore\fP
+is also needed).
+To also allow subkeys of a specified key, add a "\fB+\fP" behind a key.
+.TP
+.B IgnoreRelease: yes
+If this is present, no
+.B InRelease
+or
+.B Release
+file will be downloaded and thus the md5sums of the other
+index files will not be checked.
+.TP
+.B GetInRelease: no
+IF this is present, no
+.B InRelease
+file is downloaded but only
+.B Release
+(and
+.B Release.gpg
+)
+are tried.
+.TP
+.B Flat
+If this field is in an update rule, it is supposed to be a
+flat repository, i.e. a repository without a \fBdists\fP
+dir and no subdirectories for the index files.
+(If the corresponding \fBsources.list\fP line has the suite
+end with a slash, then you might need this one.)
+The argument for the \fBFlat:\fP field is the Component to
+put those packages into.
+No \fBComponents\fP or \fBUDebComponents\fP
+fields are allowed in a flat update rule.
+If the \fBArchitecture\fP field has any \fB>\fP items,
+the part left of the "\fB>\fP" is ignored.
+.br
+For example the \fBsources.list\fP line
+ deb http://cran.r\-project.org/bin/linux/debian etch\-cran/
+.br
+would translate to
+.br
+ Name: R
+ Method: http://cran.r\-project.org/bin/linux/debian
+ Suite: etch\-cran
+ Flat: whatevercomponentyoudlikethepackagesin
+.TP
+.B IgnoreHashes
+This directive tells reprepro to not check the listed
+hashes in the downloaded Release file (and only in the Release file).
+Possible values are currently \fBmd5\fP, \fBsha1\fP and \fBsha256\fP.
+
+Note that this does not speed anything
+up in any measurable way. The only reason to specify this if
+the Release file of the distribution you want to mirror from
+uses a faulty algorithm implementation.
+Otherwise you will gain nothing and only lose security.
+.TP
+.B FilterFormula
+This can be a formula to specify which packages to accept from
+this source. The format is misusing the parser intended for
+Dependency lines. To get only architecture all packages use
+"architecture (== all)", to get only at least important
+packages use "priority (==required) | priority (==important)".
+
+See the description of the listfilter command for the semantics
+of formulas.
+.TP
+.B FilterList\fR, \fPFilterSrcList
+These two options each take at least two arguments:
+The first argument is the fallback (default) action.
+All following arguments are treated as file names of lists.
+
+The filenames are considered to be relative to
+.B \-\-confdir\fR,
+if not starting with
+.BR ~/ ", " +b/ ", " +c/ " or " / "."
+
+Each list file consists of lines with a package name
+followed by whitespaced followed by an action.
+
+Each list may only contain a single line for a given package name.
+The action to be taken is the action specified by the first file
+mentioning that package.
+If no list file mentions a package, the fallback action is used instead.
+
+This format is inspired by dpkg \-\-get\-selections before multiarch
+and the names of the actions likely only make sense if you imagine the
+file to be the output of this command of an existing system.
+
+For each package available in the distribution to be updated from/pulled from
+this action is determined and affects the current decision what to do
+to the target distribution.
+(Only after all update/pull rules for a given target distribution have been
+processed something is actually done).
+
+The possible action keywords are:
+.RS
+.TP
+.B install
+mark the available package to be added to the target distribution unless
+the same version or a higher version is already marked as to be added/kept.
+(Note that without a prior delete rule (\fB\-\fP) or \fBsupersede\fP action,
+this will never downgrade a package as the already existing version
+is marked to be kept).
+.TP
+.B upgradeonly
+like \fBinstall\fP but will not add new packages to a distribution.
+.TP
+.B supersede
+unless the current package version is higher than the available package version,
+mark the package to be deleted in the target distribution.
+(Useful to remove packages in add-on distributions once they reached the base distribution).
+.TP
+.BR deinstall " or " purge
+ignore the newly available package.
+.TP
+.B warning
+print a warning message to stderr if a new package/newer version is available.
+Otherwise ignore the new package (like with \fBdeinstall\fP or \fBpurge\fP).
+.TP
+.B hold
+the new package is ignored, but every previous decision to
+downgrade or delete the package in the target distribution is reset.
+.TP
+.B error
+abort the whole upgrade/pull if a new package/newer version is available
+.TP
+.B "= \fIversion\fP"
+If the candidate package has the given version, behave like \fBinstall\fP.
+Otherwise continue as if this list file did not mention this package
+(i.e. look in the remaining list files or use the fallback action).

+This field controls whether source packages with Extra-Source-Only
+set are ignore when getting source packages.
+Without this option or if it is true, those source packages
+are ignored, while if set to no or false, those source packages

+.B ListHook
+If this is given, it is executed for all downloaded index files
+with the downloaded list as first and a filename that will
+be used instead of this. (e.g. "ListHook: /bin/cp" works

+If a file will be read multiple times, it is processed multiple
+times, with the environment variables
+.BR REPREPRO_FILTER_CODENAME ", " REPREPRO_FILTER_PACKAGETYPE ", "

+set to the where this file will be added and

+.br
+ListShellHook: grep\-dctrl \-X \-S apt \-o \-X \-S dpkg || [ $? \-eq 1 ]

+.B DownloadListsAs
+The arguments of this field specify which index files reprepro

+.BR . ", " .gz ", " .bz2 ", " .lzma ", " .xz ", " .diff ", "
+.BR force.gz ", " force.bz2 ", " force.lzma ", "
+.BR force.xz ", and " force.diff "."
+
+Reprepro will try the first supported variant in the list given:
+Only compressions compiled in or for which an uncompressor was found
+are used.
+Unless the value starts with \fBforce.\fP,
+it is only tried if is found in the Release or InRelease file.
+
+The default value is \fB.diff .xz .lzma .bz2 .gz .\fP, i.e.
+download Packages.diff if listed in the Release file,
+otherwise or if not usable download .xz if
+listed in the Release file and there is a way to uncompress it,
+then .lzma if usable,
+then .bz2 if usable,
+then .gz and then uncompressed).
+
+Note there is no way to see if an uncompressed variant
+of the file is available (as the Release file always lists their
+checksums, even if not there),
+so putting '\fB.\fP' anywhere but as the last argument can mean
+trying to download a file that does not exist.
+
+Together with \fBIgnoreRelease\fP reprepro will download the first
+in this list that could be unpacked (i.e. \fBforce\fP is always assumed)
+and the default value is \fB.gz .bzip2 . .lzma .xz\fP.
+.SS conf/pulls
+This file contains the rules for pulling packages from one
+distribution to another.
+While this can also be done with update rules using the file
+or copy method and using the exported indices of that other
+distribution, this way is faster.
+It also ensures the current files are used and no copies
+are made.
+(This also leads to the limitation that pulling from one
+component to another is not possible.)
+
+Each rule consists out of the following fields:
+.TP
+.B Name
+The name of this pull rule as it can be used in the
+.B Pull
+field in conf/distributions.
+.TP
+.B From
+The codename of the distribution to pull packages from.
+.TP
+.B Components
+The components of the distribution to get from.
+
+If this field is not there,
+all components from the distribution to update are tried.
+
+A rule might list components not available in all distributions using this
+rule. In this case unknown components are silently ignored.
+(Unless you start reprepro with the \-\-fast option,
+it will warn about components unusable in all distributions using that rule.
+As exception, unusable components called \fBnone\fP are never warned about,
+for compatibility with versions prior to 3.0.0 where and empty field had
+a different meaning.)
+.TP
+.B Architectures
+The architectures to update.
+If omitted all from the distribution to pull from.
+As in
+.BR conf/updates ,
+you can use ">" to download
+from one architecture and add into another one. (And again, only useful
+with filtering to avoid packages not architecture \fBall\fP to migrate).
+.TP
+.B UDebComponents
+Like
+.B Components
+but for the udebs.
+.TP
+.B FilterFormula
+.TP
+.B FilterList
+.TP
+.B FilterSrcList
+The same as with update rules.
+.SH "OVERRIDE FILES"
+The format of override files used by reprepro
+should resemble the extended ftp\-archive format,
+to be specific it is:
+
+.B \fIpackagename\fP \fIfield name\fP \fInew value\fP
+
+For example:
+.br
+.B kernel\-image\-2.4.31\-yourorga Section protected/base
+.br
+.B kernel\-image\-2.4.31\-yourorga Priority standard
+.br
+.B kernel\-image\-2.4.31\-yourorga Maintainer That's me <me@localhost>
+.br
+.B reprepro Priority required
+
+All fields of a given package will be replaced by the new value specified
+in the override file
+with the exception of special fields starting with a dollar sign ($).
+While the field name is compared case-insensitive, it is copied in
+exactly the form in the override file there.
+(Thus I suggest to keep to the exact case it is normally found in
+index files in case some other tool confuses them.)
+More than copied is the Section header (unless \fB\-S\fP is supplied),
+which is also used to guess the component (unless \fB\-C\fP is there).
+
+Some values like \fBPackage\fP, \fBFilename\fP, \fBSize\fP or \fBMD5sum\fP
+are forbidden, as their usage would severely confuse reprepro.
+
+As an extension reprepro also supports patterns instead of packagenames.
+If the package name contains '*', '[' or '?',
+it is considered a pattern
+and applied to each package
+that is not matched by any non-pattern override nor by any previous pattern.
+
+Fieldnames starting with a dollar ($) are not be placed in the
+exported control data but have special meaning.
+Unknown ones are loudly ignored.
+Special fields are:
+
+ \fB$Component\fP: includedeb, includedsc, include and processincoming
+will put the package in the component given as value
+(unless itself overridden with \fB\-C\fP).
+Note that the proper way to specify the component is by setting the
+section field and using this extension will most likely confuse people
+and/or tools.
+
+ \fB$Delete\fP: the value is treated a fieldname and fields of that
+name are removed.
+(This way one can remove fields previously added without removing and
+re-adding the package.
+And fields already included in the package can be removed, too).
+
+.SS conf/incoming
+Every chunk is a rule set for the
+.B process_incoming
+command.
+Possible fields are:
+.TP
+.B Name
+The name of the rule-set, used as argument to the scan command to specify
+to use this rule.
+.TP
+.B IncomingDir
+The Name of the directory to scan for
+.B .changes
+files.
+.TP
+.B TempDir
+A directory where the files listed in the processed .changes files
+are copied into before they are read.
+You can avoid some copy operations by placing this directory
+within the same mount point the pool hierarchy
+is (at least partially) in.
+.TP
+.B LogDir
+A directory where .changes files, .log files, .buildinfo files
+and otherwise unused .byhand files are stored upon procession.
+.TP
+.B Allow
+Each argument is either a pair \fIname1\fB>\fIname2\fR or simply
+\fIname\fP which is short for \fIname\fB>\fIname\fR.
+Each \fIname2\fP must identify a distribution,
+either by being Codename, a unique Suite, or a unique AlsoAcceptFor
+from \fBconf/distributions\fP.
+Each upload has each item in its
+.B Distribution:
+header compared first to last with each \fIname1\fP in the rules
+and is put in the first one accepting this package. e.g.:
+.br
+Allow: local unstable>sid
+.br
+or
+.br
+Allow: stable>security\-updates stable>proposed\-updates
+.br
+(Note that this makes only sense if Multiple is set to true or if
+there are people only allowed to upload to proposed\-updates but
+not to security\-updates).
+.TP
+.B Default \fIdistribution
+Every upload not put into any other distribution because
+of an Allow argument is put into \fIdistribution\fP if that
+accepts it.
+.TP
+.B Multiple
+Old form of Options: multiple_distributions.
+.TP
+.B Options
+A list of options
+.br
+.B multiple_distributions
+.br
+Allow including a upload in multiple distributions.
+
+If a .changes file lists multiple distributions,
+then reprepro will start with the first name given,
+check all Accept and Default options till it finds
+a distribution this upload can go into.
+
+If this found no distribution or if this option was given,
+reprepro will then do the same with the second distribution name
+given in the .changes file and so on.
+.br
+.B limit_arch_all
+.br
+If an upload contains binaries from some architecture and architecture
+all packages,
+the architecture all packages are only put into the architectures within
+this upload.
+Useful to combine with the \fBflood\fP command.
+.TP
+.B Permit
+A list of options to allow things otherwise causing errors:
+.br
+.B unused_files
+.br
+Do not stop with error if there are files listed in the \fB.changes\fP
+file if it lists files not belonging to any package in it.
+.br
+.B older_version
+.br
+Ignore a package not added because there already is a strictly newer
+version available instead of treating this as an error.
+.br
+.B unlisted_binaries
+.br
+Do not abort with an error if a .changes file contains .deb files that
+are not listed in the Binaries header.
+.TP
+.B Cleanup \fIoptions
+A list of options to cause more files in the incoming directory to be
+deleted:
+.br
+.B unused_files
+.br
+If there is \fBunused_files\fP in \fBPermit\fP then also delete those
+files when the package is deleted after successful processing.
+.br
+.B unused_buildinfo_files
+.br
+If .buildinfo files of processed .changes files are not used (neither
+stored by LogDir nor with Tracking: includebuildinfos) then delete them
+from the incoming dir.
+(This option has no additional effect if \fBunused_files\fP is already used.)
+.br
+.B on_deny
+.br
+If a \fB.changes\fP file is denied processing because of missing signatures
+or allowed distributions to be put in, delete it and all the files it references.
+.br
+.B on_error
+.br
+If a \fB.changes\fP file causes errors while processing, delete it and the files
+it references.
+
+Note that allowing cleanup in publicly accessible incoming queues allows a denial
+of service by sending in .changes files deleting other peoples files before they
+are completed.
+Especially when .changes files are handled directly (e.g. by inoticoming).
+
+.TP
+.B MorgueDir
+If files are to be deleted by Cleanup, they are instead moved to a subdirectory
+of the directory given as value to this field.
+This directory has to be on the same partition as the incoming directory and
+files are moved (i.e. owner and permission stay the same) and never copied.
+
+.SH "UPLOADERS FILES"
+These files specified by the \fBUploaders\fP header in the distribution
+definition as explained above describe what key a \fB.changes\fP file
+as to be signed with to be included in that distribution.
+.P
+Empty lines and lines starting with a hash are ignored, every other line
+must be of one of the following nine forms or an include directive:
+.TP
+.B allow \fIcondition\fP by anybody
+which allows everyone to upload packages matching \fIcondition\fP,
+.TP
+.B allow \fIcondition\fP by unsigned
+which allows everything matching that has no pgp/gpg header,
+.TP
+.B allow \fIcondition\fP by any key
+which allows everything matching with any valid signature in or
+.TP
+.B allow \fIcondition\fP by key \fIkey-id\fP
+which allows everything matching signed by this \fIkey-id\fP
+(to be specified without any spaces).
+If the \fIkey-id\fP ends with a \fB+\fP (plus), a signature with a subkey of
+this primary key also suffices.
+
+\fIkey-id\fP must be a suffix of the id libgpgme uses to identify this key,
+i.e. a number of hexdigits from the end of the fingerprint of the key, but
+no more than what libgpgme uses.
+(The maximal number should be what gpg \-\-list-key \-\-with\-colons prints,
+as of the time of this writing that is at most 16 hex-digits).
+.TP
+.B allow \fIcondition\fP by group \fIgroupname\fP
+which allows every member of group \fIgroupname\fP.
+Groups can be manipulated by
+.TP
+.B group \fIgroupname\fP add \fIkey-id\fP
+to add a \fIkey-id\fP (see above for details) to this group, or
+.TP
+.B group \fIgroupname\fP contains \fIgroupname\fP
+to add a whole group to a group.
+
+To avoid warnings in incomplete config files there is also
+.TP
+.B group \fIgroupname\fP empty
+to declare a group has no members (avoids warnings that it is used without those)
+and
+.TP
+.B group \fIgroupname\fP unused
+to declare that a group is not yet used (avoid warnings that it is not used).
+.PP
+A line starting with \fBinclude\fP causes the rest of the line to be
+interpreted as filename, which is opened and processed before the rest
+of the file is processed.
+
+The only conditions currently supported are:
+.TP
+.B *
+which means any package,
+.TP
+.BI "source '" name '
+which means any package with source \fIname\fP.
+('\fB*\fP', '\fB?\fP' and '\fB[\fP..\fB]\fP' are treated as in shell wildcards).
+.TP
+.B sections '\fIname\fP'\fR(\fP|'\fIname\fP'\fR)*\fP
+matches an upload in which each section matches one of the names
+given.
+As upload conditions are checked very early,
+this is the section listed in the .changes file,
+not the one from the override file.
+(But this might change in the future,
+if you have the need for the one or the other behavior, let me know).
+.TP
+.B sections contain '\fIname\fP'\fR(\fP|'\fIname\fP'\fR)*\fP
+The same, but not all sections must be from the given set,
+but at least one source or binary package needs to have one of those given.
+.TP
+.B binaries '\fIname\fP'\fR(\fP|'\fIname\fP'\fR)*\fP
+matches an upload in which each binary (type deb or udeb)
+matches one of the names given.
+.TP
+.B binaries contain '\fIname\fP'\fR(\fP|'\fIname\fP'\fR)*\fP
+again only at least one instead of all is required.
+.TP
+.B architectures '\fIarchitecture\fP'\fR(\fP|'\fIname\fP'\fR)*\fP
+matches an upload in which each package has only architectures
+from the given set.
+\fBsource\fP and \fBall\fP are treated as unique architectures.
+Wildcards are not allowed.
+.TP
+.B architectures contain '\fIarchitecture\fP'\fR(\fP|'\fIarchitecture\fP'\fR)*\fP
+again only at least one instead of all is required.
+.TP
+.B byhand
+matches an upload with at least one byhand file
+(i.e. a file with section \fBbyhand\fP or \fBraw\-\fP\fIsomething\fP).
+.TP
+.B byhand '\fIsection\fP'\fR(\fP|'\fIsection\fP'\fR)*\fP
+matches an upload with at least one byhand file and
+all byhand files having a section listed in the list of given section.
+(i.e. \fBbyhand 'byhand'|'raw\-*'\fP is currently is the same as \fBbyhand\fP).
+.TP
+.BI "distribution '" codename '
+which means any package when it is to be included in \fIcodename\fP.
+As the uploaders file is given by distribution, this is only useful
+to reuse a complex uploaders file for multiple distributions.
+.PP
+Putting \fBnot\fP in front of a condition, inverses it's meaning.
+For example
+.br
+\fBallow not source 'r*' by anybody\fP
+.br
+means anybody may upload packages which source name does not start
+with an 'r'.
+.PP
+Multiple conditions can be connected with \fBand\fP and \fBor\fP,
+with \fBor\fP binding stronger (but both weaker than \fBnot\fP).
+That means
+.br
+\fBallow source 'r*' and source '*xxx' or source '*o' by anybody\fP
+.br
+is equivalent to
+.br
+\fBallow source 'r*xxx' by anybody\fP
+.br
+\fBallow source 'r*o' by anybody\fP
+
+(Other conditions
+will follow once somebody tells me what restrictions are useful.
+Currently planned is only something for architectures).
+.SH "ERROR IGNORING"
+With \fB\-\-ignore\fP on the command line or an \fIignore\fP
+line in the options file, the following type of errors can be
+ignored:
+.TP
+.B brokenold \fR(hopefully never seen)
+If there are errors parsing an installed version of package, do not
+error out, but assume it is older than anything else, has not files
+or no source name.
+.TP
+.B brokensignatures
+If a .changes or .dsc file contains at least one invalid signature
+and no valid signature (not even expired or from an expired or revoked key),
+reprepro assumes the file got corrupted and refuses to use it unless this
+ignore directive is given.
+.TP
+.B brokenversioncmp \fR(hopefully never seen)
+If comparing old and new version fails, assume the new one is newer.
+.TP
+.B dscinbinnmu
+If a .changes file has an explicit Source version that is different the
+to the version header of the file,
+than reprepro assumes it is binary non maintainer upload (NMU).
+In that case, source files are not permitted in .changes files
+processed by
+.B include
+or
+.BR processincoming .
+Adding \fB\-\-ignore=dscinbinnmu\fP allows it for the \fBinclude\fP
+command.
+.TP
+.B emptyfilenamepart \fR(insecure)
+Allow strings to be empty that are used to construct filenames.
+(like versions, architectures, ...)
+.TP
+.B extension
+Allow one to \fBincludedeb\fP files that do not end with \fB.deb\fP,
+to \fBincludedsc\fP files not ending in \fB.dsc\fP and to
+\fBinclude\fP files not ending in \fB.changes\fP.
+.TP
+.B forbiddenchar \fR(insecure)
+Do not insist on Debian policy for package and source names
+and versions.
+Thus allowing all 7-bit characters but slashes (as they would
+break the file storage) and things syntactically active
+(spaces, underscores in filenames in .changes files, opening
+parentheses in source names of binary packages).
+To allow some 8-bit chars additionally, use \fB8bit\fP additionally.
+.TP
+.B 8bit \fR(more insecure)
+Allow 8-bit characters not looking like overlong UTF-8 sequences
+in filenames and things used as parts of filenames.
+Though it hopefully rejects overlong UTF-8 sequences, there might
+be other characters your filesystem confuses with special characters,
+thus creating filenames possibly equivalent to
+\fB/mirror/pool/main/../../../etc/shadow\fP
+(Which should be safe, as you do not run reprepro as root, do you?)
+or simply overwriting your conf/distributions file adding some commands
+in there. So do not use this if you are paranoid, unless you are paranoid
+enough to have checked the code of your libs, kernel and filesystems.
+.TP
+.B ignore \fR(for forward compatibility)
+Ignore unknown ignore types given to \fI\-\-ignore\fP.
+.TP
+.B flatandnonflat \fR(only suppresses a warning)
+Do not warn about a flat and a non-flat distribution from the same
+source with the same name when updating.
+(Hopefully never ever needed.)
+.TP
+.B malformedchunk \fR(I hope you know what you do)
+Do not stop when finding a line not starting with a space but
+no colon(:) in it. These are otherwise rejected as they have no
+defined meaning.
+.TP
+.B missingfield \fR(safe to ignore)
+Ignore missing fields in a .changes file that are only checked but
+not processed.
+Those include: Format, Date, Urgency, Maintainer, Description, Changes
+.TP
+.B missingfile \fR(might be insecure)
+When including a .dsc file from a .changes file,
+try to get files needed but not listed in the .changes file
+(e.g. when someone forgot to specify \-sa to dpkg\-buildpackage)
+from the directory the .changes file is in instead of erroring out.
+(\fB\-\-delete\fP will not work with those files, though.)
+.TP
+.B spaceonlyline \fR(I hope you know what you do)
+Allow lines containing only (but non-zero) spaces. As these
+do not separate chunks as thus will cause reprepro to behave
+unexpected, they cause error messages by default.
+.TP
+.B surprisingarch
+Do not reject a .changes file containing files for a
+architecture not listed in the Architecture-header within it.
+.TP
+.B surprisingbinary
+Do not reject a .changes file containing .deb files containing
+packages whose name is not listed in the "Binary:" header
+of that changes file.
+.TP
+.B undefinedtarget \fR(hope you are not using the wrong db directory)
+Do not stop when the packages.db file contains databases for
+codename/packagetype/component/architectures combinations that are
+not listed in your distributions file.
+
+This allows you to temporarily remove some distribution from the config files,
+without having to remove the packages in it with the \fBclearvanished\fP
+command.
+You might even temporarily remove single architectures or components,
+though that might cause inconsistencies in some situations.
+.TP
+.B undefinedtracking \fR(hope you are not using the wrong db directory)
+Do not stop when the tracking file contains databases for
+distributions that are not listed in your \fBdistributions\fP file.
+
+This allows you to temporarily remove some distribution from the config files,
+without having to remove the packages in it with the \fBclearvanished\fP
+command.
+You might even temporarily disable tracking in some distribution, but that
+is likely to cause inconsistencies in there, if you do not know, what you
+are doing.
+.TP
+.B unknownfield \fR(for forward compatibility)
+Ignore unknown fields in the config files, instead of refusing to run
+then.
+.TP
+.B unusedarch \fR(safe to ignore)
+No longer reject a .changes file containing no files for any of the
+architectures listed in the Architecture-header within it.
+.TP
+.B unusedoption
+Do not complain about command line options not used by the
+specified action (like \fB\-\-architecture\fP).
+.TP
+.B uploaders
+The include command will accept packages that would otherwise been
+rejected by the uploaders file.
+.TP
+.B wrongarchitecture \fR(safe to ignore)
+Do not warn about wrong "Architecture:" lines in downloaded
+Packages files.
+(Note that wrong Architectures are always ignored when getting
+stuff from flat repositories or importing stuff from one architecture
+to another).
+.TP
+.B wrongdistribution \fR(safe to ignore)
+Do not error out if a .changes file is to be placed in a
+distribution not listed in that files' Distributions: header.
+.TP
+.B wrongsourceversion
+Do not reject a .changes file containing .deb files with
+a different opinion on what the version of the source package is.
+.br
+(Note: reprepro only compares literally here, not by meaning.)
+.TP
+.B wrongversion
+Do not reject a .changes file containing .dsc files with
+a different version.
+.br
+(Note: reprepro only compares literally here, not by meaning.)
+.TP
+.B expiredkey \fR(I hope you know what you do)
+Accept signatures with expired keys.
+(Only if the expired key is explicitly requested).

+(Only if the revoked key is explicitly requested).
+.SH GUESSING
+When including a binary or source package without explicitly
+declaring a component with
+.B \-C
+it will take the
+first component with the name of the section, being
+prefix to the section, being suffix to the section
+or having the section as prefix or any. (In this order)
+
+Thus having specified the components:
+"main non\-free contrib non\-US/main non\-US/non\-free non\-US/contrib"
+should map e.g.
+"non\-US" to "non\-US/main" and "contrib/editors" to "contrib",
+while having only "main non\-free and contrib" as components should
+map "non\-US/contrib" to "contrib" and "non\-US" to "main".
+
+.B NOTE:
+Always specify main as the first component, if you want things
+to end up there.
+
+.B NOTE:
+unlike in dak, non\-US and non\-us are different things...
+.SH NOMENCLATURE
+.B Codename
+the primary identifier of a given distribution. This are normally
+things like \fBsarge\fP, \fBetch\fP or \fBsid\fP.
+.TP
+.B basename
+the name of a file without any directory information.
+.TP
+.B byhand
+Changes files can have files with section 'byhand' (Debian) or 'raw\-' (Ubuntu).
+Those files are not packages but other data generated (usually together with
+packages) and then uploaded together with this changes files.
+
+With reprepro those can be stored in the pool next to their packages with
+tracking, put in some log directory when using processincoming, or given to
+an hook script (currently only possible with processincoming).
+.TP

+the position relative to the outdir. (as found in "Filename:" in Packages.gz)
+.TP
+.B "full filename"
+the position relative to /
+.TP
+.B architecture
+The term like \fBsparc\fP, \fBi386\fP, \fBmips\fP, ... .
+To refer to the source packages, \fBsource\fP
+is sometimes also treated as architecture.

+.SS The magic delete rule ("\-").
+A minus as a single word in the

+to get packages even if they have (strict) lower versions. The mark will
+get removed if a later rule sets the package on hold (hold is not yet implemented,
+in case you might wonder) or would get a package with the same version
+(Which it will not, see above). If the mark is still there at the end of the processing,
+the package will get removed.
+.P
+Thus the line "Update: \-
+.I rules
+" will cause all packages to be exactly the
+highest Version found in
+.I rules.
+The line "Update:
+.I near
+\-
+.I rules
+" will do the same, except if it needs to download packages, it might download
+it from
+.I near
+except when too confused. (It will get too confused e.g. when
+.I near
+or
+.I rules
+have multiple versions of the package and the highest in
+.I near
+is not the first one in
+.I rules,
+as it never remember more than one possible spring for a package.
+.P
+Warning: This rule applies to all type/component/architecture triplets
+of a distribution, not only those some other update rule applies to.
+(That means it will delete everything in those!)
+.SH ENVIRONMENT VARIABLES
+Environment variables are always overwritten by command line options,
+but overwrite options set in the \fBoptions\fP file. (Even when the
+options file is obviously parsed after the environment variables as
+the environment may determine the place of the options file).
+.TP
+.B REPREPRO_BASE_DIR
+The directory in this variable is used instead of the current directory,
+if no \fB\-b\fP or \fB\-\-basedir\fP options are supplied.
+.br
+It is also set in all hook scripts called by reprepro
+(relative to the current directory or absolute,
+depending on how reprepro got it).
+.TP
+.B REPREPRO_CONFIG_DIR
+The directory in this variable is used when no \fB\-\-confdir\fP is
+supplied.
+.br
+It is also set in all hook scripts called by reprepro
+(relative to the current directory or absolute,
+depending on how reprepro got it).
+.TP
+.B REPREPRO_OUT_DIR
+This is not used, but only set in hook scripts called by reprepro
+to the directory in which the \fBpool\fP subdirectory resides
+(relative to the current directory or absolute,
+depending on how reprepro got it).
+.TP
+.B REPREPRO_DIST_DIR
+This is not used, but only set in hook scripts called by reprepro
+to the \fBdists\fP directory (relative to the current directory or
+absolute, depending on how reprepro got it).
+.TP
+.B REPREPRO_LOG_DIR
+This is not used, but only set in hook scripts called by reprepro
+to the value setable by \fB\-\-logdir\fP.
+.TP
+.B REPREPRO_CAUSING_COMMAND
+.TP
+.B REPREPRO_CAUSING_FILE
+Those two environment variable are set (or unset) in
+\fBLog:\fP and \fBByHandHooks:\fP scripts and hint what command
+and what file caused the hook to be called (if there is some).
+.TP
+.B REPREPRO_CAUSING_RULE
+This environment variable is set (or unset) in
+\fBLog:\fP scripts and hint what update or pull rule caused
+this change.
+.TP
+.B REPREPRO_FROM
+This environment variable is set (or unset) in
+\fBLog:\fP scripts and denotes what other distribution a
+package is copied from (with pull and copy commands).
+.TP
+.B REPREPRO_FILTER_ARCHITECTURE
+.TP
+.B REPREPRO_FILTER_CODENAME
+.TP
+.B REPREPRO_FILTER_COMPONENT
+.TP
+.B REPREPRO_FILTER_PACKAGETYPE
+.TP
+.B REPREPRO_FILTER_PATTERN
+Set in \fBFilterList:\fP and \fBFilterSrcList:\fP scripts.
+.TP
+.B GNUPGHOME
+Not used by reprepro directly.
+But reprepro uses libgpgme, which calls gpg for signing and verification
+of signatures.
+And your gpg will most likely use the content of this variable
+instead of "~/.gnupg".
+Take a look at
+.BR gpg (1)
+to be sure.
+You can also tell reprepro to set this with the \fB\-\-gnupghome\fP option.
+.TP
+.B GPG_TTY
+When there is a gpg\-agent running that does not have the passphrase
+cached yet, gpg will most likely try to start some pinentry program
+to get it.
+If that is pinentry\-curses, that is likely to fail without this
+variable, because it cannot find a terminal to ask on.
+In this cases you might set this variable to something like
+the value of
+.B $(tty)
+or
+.B $SSH_TTY
+or anything else denoting a usable terminal. (You might also
+want to make sure you actually have a terminal available.
+With ssh you might need the
+.B \-t
+option to get a terminal even when telling gpg to start a specific command).
+
+By default, reprepro will set this variable to what the symbolic link
+.B /proc/self/fd/0
+points to, if stdin is a terminal, unless you told with
+.B \-\-noguessgpgtty
+to not do so.
+.SH BUGS
+Increased verbosity always shows those things one does not want to know.
+(Though this might be inevitable and a corollary to Murphy)
+
+Reprepro uses berkeley db, which was a big mistake.
+The most annoying problem not yet worked around is database corruption
+when the disk runs out of space.
+(Luckily if it happens while downloading packages while updating,
+only the files database is affected, which is easy (though time consuming)
+to rebuild, see \fBrecovery\fP file in the documentation).
+Ideally put the database on another partition to avoid that.
+
+While the source part is mostly considered as the architecture
+.B source
+some parts may still not use this notation.
+.SH "WORK-AROUNDS TO COMMON PROBLEMS"
+.TP
+.B gpgme returned an impossible condition
+With the woody version this normally meant that there was no .gnupg
+directory in $HOME, but it created one and reprepro succeeds when called
+again with the same command.
+Since sarge the problem sometimes shows up, too. But it is no longer
+reproducible and it does not fix itself, neither. Try running
+\fBgpg \-\-verify \fP\fIfile-you-had-problems-with\fP manually as the
+user reprepro is running and with the same $HOME. This alone might
+fix the problem. It should not print any messages except perhaps
+.br
+gpg: no valid OpenPGP data found.
+.br
+gpg: the signature could not be verified.
+.br
+if it was an unsigned file.
+.TP
+.B not including .orig.tar.gz when a .changes file's version does not end in \-0 or \-1
+If dpkg\-buildpackage is run without the \fB\-sa\fP option to build a version with
+a Debian revision not being \-0 or \-1, it does not list the \fB.orig.tar.gz\fP file
+in the \fB.changes\fP file.
+If you want to \fBinclude\fP such a file with reprepro
+when the .orig.tar.gz file does not already exist in the pool, reprepro will report
+an error.
+This can be worked around by:
+.br
+call \fBdpkg\-buildpackage\fP with \fB\-sa\fP (recommended)
+.br
+copy the .orig.tar.gz file to the proper place in the pool before
+.br
+call reprepro with \-\-ignore=missingfile (discouraged)
+.TP
+.B leftover files in the pool directory.
+reprepro is sometimes a bit too timid of deleting stuff. When things
+go wrong and there have been errors it sometimes just leaves everything
+where it is.
+To see what files reprepro remembers to be in your pool directory but
+does not know anything needing them right know, you can use
+.br
+\fBreprepro dumpunreferenced\fP
+.br
+To delete them:
+.br
+\fBreprepro deleteunreferenced\fP
+.SH INTERRUPTING
+Interrupting reprepro has its problems.
+Some things (like speaking with apt methods, database stuff) can cause
+problems when interrupted at the wrong time.
+Then there are design problems of the code making it hard to distinguish
+if the current state is dangerous or non-dangerous to interrupt.
+Thus if reprepro receives a signal normally sent to tell a process to
+terminate itself softly,
+it continues its operation, but does not start any new operations.
+(I.e. it will not tell the apt\-methods any new file to download, it will
+not replace a package in a target, unless it already had started with it,
+it will not delete any files gotten dereferenced, and so on).
+
+\fBIt only catches the first signal of each type. The second signal of a
+given type will terminate reprepro. You will risk database corruption
+and have to remove the lockfile manually.\fP
+
+Also note that even normal interruption leads to code-paths mostly untested
+and thus expose a multitude of bugs including those leading to data corruption.
+Better think a second more before issuing a command than risking the need
+for interruption.

+.TH RREDTOOL 1 "2009-11-12" "reprepro" REPREPRO
+.SH NAME
+rredtool \- merge or apply a very restricted subset of ed patches
+.SH SYNOPSIS
+.B rredtool \-\-help
+
+.B rredtool
+[
+\fIoptions\fP
+]
+.B \-\-merge
+.I patches...
+
+.B rredtool
+[
+\fIoptions\fP
+]
+.B \-\-patch
+.IR file-to-patch " " patches...
+
+.B rredtool
+.IR directory " " newfile " " oldfile " " mode
+.SH DESCRIPTION
+rredtool is a tool to handle a subset of ed patches in a safe way.
+It is especially targeted at ed patches as used in Packages.diff
+and Sources.diff.
+Is also has a mode supposed to be called from reprepro as Index Hook
+to generate and update a \fBPackages.diff/Index\fP file.
+.SH "MODI"
+One of the following has to be given, so that rredtool know that to
+do.
+.TP
+.B \-\-version
+Print the version of this tool
+(or rather the version of reprepro which it is coming with).
+.TP
+.B \-\-help
+Print a short overview of the modi.
+.TP
+.B \-\-patch
+The first argument of rredtool is the file to patch,
+the other arguments are ed patches to apply on this one.
+.TP
+.B \-\-merge
+The arguments are treated as ed patches, which are merged into
+a single one.
+.TP
+.BR \-\-reprepro\-hook " (or no other mode flag)
+Act as reprepro index hook to manage a \fBPackages.diff/index\fP file.
+That means it expects to get exactly 4 arguments
+and writes the names of files to place into filedescriptor 3.
+
+If neither \-\-patch nor \-\-merge is given,
+this mode is used, so you can just put
+
+ \fBDebIndices: Packages Release . .gz /usr/bin/rredtool\fP
+
+into reprepro's \fBconf/distributions\fP file to have a Packages.diff
+directory generated.
+(Note that you have to generate an uncompressed file (the single dot).
+You will need to have patch, gzip and gunzip available in your path.)
+
+.SH "OPTIONS"
+.TP
+.B \-\-debug
+Print intermediate results or other details that might be interesting
+when trying to track down bugs in rredtool but not intresting otherwise.
+.TP
+.B \-\-max\-patch\-count=\fIcount\fP
+When generating a \fIPackages\fP\fB.diff/Index\fP file,
+put at most \fIcount\fP patches in it
+(not counting possible apt workaround patches).
+.TP
+.BR \-o | \-\-output
+Not yet implemented.
+.SH "ENVIRONMENT"
+.TP
+.BR TMPDIR ", " TEMPDIR
+temporary files are created in $\fITEMPDIR\fP if set,
+otherwise in $\fITMPDIR\fP if set, otherwise in \fB/tmp/\fP.
+.SH "REPORTING BUGS"
+Report bugs or wishlist requests the Debian BTS
+(e.g. by using \fBreportbug reperepro\fP)
+or directly to <brlink@debian.org>.

+This short HOW-TO describes how to setup a repository using reprepro.
+
+First choose a directory where you want to store your repository,
+
+1) Configuration:
+
+Generate a directory named conf/.
+
+Create a file named "distributions" there.
+
+Add entries such as:
+
+Origin: Debian
+Label: Debian-All
+Suite: stable
+Codename: woody
+Version: 3.0
+Architectures: i386 sparc mips source
+Components: main non-free contrib
+Description: Debian woody + woody/non-US + woody/updates
+#Update: debian non-US security
+#SignWith: yes
+
+Or:
+
+Origin: PCPool
+Label: PCPool
+Suite: stable
+Codename: pcpool
+Version: 3.0
+Architectures: i386 source
+Components: main non-free contrib bad protected server
+UDebComponents: main
+Description: PCPool specific (or backported) packages
+SignWith: yes
+DebOverride: override
+UDebOverride: override
+DscOverride: srcoverride
+
+Multiple entries are separated with an empty line.
+
+The codename of the distribution is specified with Codename:.
+It is the primary name of a distribution and e.g. used to determine the
+directory to create and put the index files into.
+
+Update: is described later.
+
+If SignWith: is there, it will try to sign it: either use "yes" or give
+something gpg can use to identify the key you want to use.
+
+The other fields are copied into the appropriate "Release" files generated.
+
+2) Adding files to the repository:
+
+To add a .deb manually:
+
+reprepro -Vb . includedeb pcpool /var/cache/apt/archives/libc6_2.2.5-11.8_i386.deb
+
+to add a .changes file:
+
+reprepro -Vb . include pcpool test.changes
+
+Hint: you can add "-C component", "-A architecture", "-S section" and "-P
+priority" to give additional hints where it should go. Note -A will not
+overwrite something to go into another architecture, but simply ignore those
+not fitting, only "Architecture: all" packages are placed exactly in these
+architecture. Helps when it is not available for all architectures and each
+binary version needs a fitting version of the "Architecture: all" package.
+
+3) Removing files from the repository:
+
+reprepro -Vb . remove pcpool libc6
+
+to only remove from a specific component or architecture:
+
+reprepro -Vb . -C main -A i386 remove pcpool libc6
+
+4) Getting information about a package:
+
+To see in which architectures/components a package exists and which version it
+uses.
+
+reprepro -b . list pcpool libc6
+
+5) Override-Files:
+
+When including packages via "includedeb", "includedsc" or "include"
+the applicable override file from the distribution it is placed
+into is used. The file given by DebOverride: for ".deb"s, the
+file given by UDebOverride: for ".udeb"s and the file given by
+DscOverride: for ".dsc"s. If the filename starts with
+a slash (/) it is not relative to the conf directory given
+with --conf, defaulting to "conf" in the current directory (or in the
+directory specified with --basedir, if that is given).
+
+Note that the Format is those of apt-ftparchive's ExtraOverride, not the old format.
+An (stupid) example line for that file would be:
+libc6 Priority extra
+
+6) importing from upstream repositories:
+
+The file conf/updates can contain entries like this:
+
+Name: debian
+Method: http://ftp.debian.de/debian
+VerifyRelease: F1D53D8C4F368D5D
+
+Name: non-US
+Method: http://ftp.debian.de/debian-non-US
+Suite: */non-US
+Architectures: i386 sparc mips source
+Components: main>main non-free>non-free contrib>contrib
+UDebComponents:
+VerifyRelease: B629A24C38C6029A
+
+Name: security
+Method: http://security.debian.org/debian-security
+Suite: */updates
+UDebComponents:
+VerifyRelease: F1D53D8C4F368D5D
+
+Which of those are used is determined by the Update: line
+in the description in conf/distributions. When Suite:,
+Architecture:, Components: or UDebComponents: are not given,
+those of the distribution to be added are used.
+The suite of the target can be used as "*" in the Suite: here.
+VerifyRelease: tells which GPG key to use checking the Release.gpg.
+
+Add a "IgnoreRelease: yes" to ignore any Release files.
+
+To import components in other components, use the source>target
+syntax.
+
+Method: describes an apt-method, for which the programs
+from /usr/lib/apt/methods are used...
+
+To update everything possible do:
+
+reprepro -b . update
+
+To only update some distributions do:
+
+reprepro -b . update woody
+
+There is no support for updating a distribution from only specific
+ upstreams yet. You will have to edit conf/distributions for that.
+
+The value for VerifyRelease: can be retrieved using:
+
+gpg --with-colons --list-keys <whatever>
+
+===============================================================================
+The following is from V. Stanley Jaddoe <debian@terabytemusic.cjb.net>.
+Make sure to include all sources when allowing everyone access to software
+only available under GPL to you. Well, you should always supply sources,
+but in some cases not doing so might cause you trouble.
+
+Using reprepro with apache2 (sarge, etch, sid)
+
+This example assumes the reprepro repository is under /srv/reprepro/ and that
+apache2 has been correctly installed and configured.
+
+The first step is to create a virtual directory called debian/. Assuming your
+server runs the host http://www.example.com/, the web repository will be
+placed at http://www.example.com/debian/.
+
+Create an apache2 config file in the conf dir of your reprepro repository,
+using the following command:
+
+cat > /srv/reprepro/conf/apache.conf << EOF
+Alias /debian /srv/reprepro/
+<Directory /srv/reprepro>
+ Options +Indexes
+ AllowOverride None
+ order allow,deny
+ allow from all
+</Directory>
+EOF
+
+To enable this virtual directory, a symlink has to be created. This can be done
+using the following command:
+
+ln -s /srv/reprepro/conf/apache.conf /etc/apache2/conf.d/reprepro.conf
+
+The second step is setting the permissions in such a way that web users can
+browse the repository, but cannot view the reprepro specific configuration.
+This can be done using the following commands:
+
+chown -R root:root /srv/reprepro/
+chmod 755 /srv/reprepro/
+chown -R root:www-data /srv/reprepro/dists/ /srv/reprepro/pool/
+chmod 750 /srv/reprepro/*
+
+Reload apache2:
+
+/etc/init.d/apache2 reload
+
+Check if the repository is viewable by web-users, by pointing your browser to
+
+http://www.example.com/debian/
+
+If there are no problems with your reprepro repository and the apache2
+configuration, you should see two directories, dists/ and pool/.
+
+The last step is to add this new repository to your sources.list.
+
