+Contributed Software
+
+Although these pieces are available as part of the official git
+source tree, they are in somewhat different status. The
+intention is to keep interesting tools around git here, maybe
+even experimental ones, to give users an easier access to them,
+and to give tools wider exposure, so that they can be improved
+faster.
+
+I am not expecting to touch these myself that much. As far as
+my day-to-day operation is concerned, these subdirectories are
+owned by their respective primary authors. I am willing to help
+if users of these components and the contrib/ subtree "owners"
+have technical/design issues to resolve, but the initiative to
+fix and/or enhance things _must_ be on the side of the subtree
+owners. IOW, I won't be actively looking for bugs and rooms for
+enhancements in them as the git maintainer -- I may only do so
+just as one of the users when I want to scratch my own itch. If
+you have patches to things in contrib/ area, the patch should be
+first sent to the primary author, and then the primary author
+should ack and forward it to me (git pull request is nicer).
+This is the same way as how I have been treating gitk, and to a
+lesser degree various foreign SCM interfaces, so you know the
+drill.
+
+I expect that things that start their life in the contrib/ area
+to graduate out of contrib/ once they mature, either by becoming
+projects on their own, or moving to the toplevel directory. On
+the other hand, I expect I'll be proposing removal of disused
+and inactive ones from time to time.
+
+If you have new things to add to this area, please first propose
+it on the git mailing list, and after a list discussion proves
+there are some general interests (it does not have to be a
+list-wide consensus for a tool targeted to a relatively narrow
+audience -- for example I do not work with projects whose
+upstream is svn, so I have no use for git-svn myself, but it is
+of general interest for people who need to interoperate with SVN
+repositories in a way git-svn works better than git-svnimport),
+submit a patch to create a subdirectory of contrib/ and put your
+stuff there.

+Instructions how to use this in Visual Studio:
+
+Open the worktree as a folder. Visual Studio 2019 and later will detect
+the CMake configuration automatically and set everything up for you,
+ready to build. You can then run the tests in `t/` via a regular Git Bash.
+
+Note: Visual Studio also has the option of opening `CMakeLists.txt`
+directly; Using this option, Visual Studio will not find the source code,
+though, therefore the `File>Open>Folder...` option is preferred.
+
+Instructions to run CMake manually:
+
+ mkdir -p contrib/buildsystems/out
+ cd contrib/buildsystems/out
+ cmake ../ -DCMAKE_BUILD_TYPE=Release
+
+This will build the git binaries in contrib/buildsystems/out
+directory (our top-level .gitignore file knows to ignore contents of
+this directory).
+
+Possible build configurations(-DCMAKE_BUILD_TYPE) with corresponding
+compiler flags
+Debug : -g
+Release: -O3
+RelWithDebInfo : -O2 -g
+MinSizeRel : -Os
+empty(default) :
+
+NOTE: -DCMAKE_BUILD_TYPE is optional. For multi-config generators like Visual Studio
+this option is ignored
+
+This process generates a Makefile(Linux/*BSD/MacOS) , Visual Studio solution(Windows) by default.
+Run `make` to build Git on Linux/*BSD/MacOS.
+Open git.sln on Windows and build Git.
+
+NOTE: By default CMake uses Makefile as the build tool on Linux and Visual Studio in Windows,
+to use another tool say `ninja` add this to the command line when configuring.
+`-G Ninja`
+
+NOTE: By default CMake will install vcpkg locally to your source tree on configuration,
+to avoid this, add `-DNO_VCPKG=TRUE` to the command line when configuring.

+This directory provides examples of Coccinelle (http://coccinelle.lip6.fr/)
+semantic patches that might be useful to developers.
+
+There are two types of semantic patches:
+
+ * Using the semantic transformation to check for bad patterns in the code;
+ The target 'make coccicheck' is designed to check for these patterns and
+ it is expected that any resulting patch indicates a regression.
+ The patches resulting from 'make coccicheck' are small and infrequent,
+ so once they are found, they can be sent to the mailing list as per usual.
+
+ Example for introducing new patterns:
+ 67947c34ae (convert "hashcmp() != 0" to "!hasheq()", 2018-08-28)
+ b84c783882 (fsck: s/++i > 1/i++/, 2018-10-24)
+
+ Example of fixes using this approach:
+ 248f66ed8e (run-command: use strbuf_addstr() for adding a string to
+ a strbuf, 2018-03-25)
+ f919ffebed (Use MOVE_ARRAY, 2018-01-22)
+
+ These types of semantic patches are usually part of testing, c.f.
+ 0860a7641b (travis-ci: fail if Coccinelle static analysis found something
+ to transform, 2018-07-23)
+
+ * Using semantic transformations in large scale refactorings throughout
+ the code base.
+
+ When applying the semantic patch into a real patch, sending it to the
+ mailing list in the usual way, such a patch would be expected to have a
+ lot of textual and semantic conflicts as such large scale refactorings
+ change function signatures that are used widely in the code base.
+ A textual conflict would arise if surrounding code near any call of such
+ function changes. A semantic conflict arises when other patch series in
+ flight introduce calls to such functions.
+
+ So to aid these large scale refactorings, semantic patches can be used.
+ However we do not want to store them in the same place as the checks for
+ bad patterns, as then automated builds would fail.
+ That is why semantic patches 'contrib/coccinelle/*.pending.cocci'
+ are ignored for checks, and can be applied using 'make coccicheck-pending'.
+
+ This allows to expose plans of pending large scale refactorings without
+ impacting the bad pattern checks.
+
+Git-specific tips & things to know about how we run "spatch":
+
+ * The "make coccicheck" will piggy-back on
+ "COMPUTE_HEADER_DEPENDENCIES". If you've built a given object file
+ the "coccicheck" target will consider its depednency to decide if
+ it needs to re-run on the corresponding source file.
+
+ This means that a "make coccicheck" will re-compile object files
+ before running. This might be unexpected, but speeds up the run in
+ the common case, as e.g. a change to "column.h" won't require all
+ coccinelle rules to be re-run against "grep.c" (or another file
+ that happens not to use "column.h").
+
+ To disable this behavior use the "SPATCH_USE_O_DEPENDENCIES=NoThanks"
+ flag.
+
+ * To speed up our rules the "make coccicheck" target will by default
+ concatenate all of the *.cocci files here into an "ALL.cocci", and
+ apply it to each source file.
+
+ This makes the run faster, as we don't need to run each rule
+ against each source file. See the Makefile for further discussion,
+ this behavior can be disabled with "SPATCH_CONCAT_COCCI=".
+
+ But since they're concatenated any <id> in the <rulname> (e.g. "@
+ my_name", v.s. anonymous "@@") needs to be unique across all our
+ *.cocci files. You should only need to name rules if other rules
+ depend on them (currently only one rule is named).
+
+ * To speed up incremental runs even more use the "spatchcache" tool
+ in this directory as your "SPATCH". It aimns to be a "ccache" for
+ coccinelle, and piggy-backs on "COMPUTE_HEADER_DEPENDENCIES".
+
+ It caches in Redis by default, see it source for a how-to.
+
+ In one setup with a primed cache "make coccicheck" followed by a
+ "make clean && make" takes around 10s to run, but 2m30s with the
+ default of "SPATCH_CONCAT_COCCI=Y".
+
+ With "SPATCH_CONCAT_COCCI=" the total runtime is around ~6m, sped
+ up to ~1m with "spatchcache".
+
+ Most of the 10s (or ~1m) being spent on re-running "spatch" on
+ files we couldn't cache, as we didn't compile them (in contrib/*
+ and compat/* mostly).
+
+ The absolute times will differ for you, but the relative speedup
+ from caching should be on that order.

+#
+# spatchcache: a poor-man's "ccache"-alike for "spatch" in git.git
+#
+# This caching command relies on the peculiarities of the Makefile
+# driving "spatch" in git.git, in particular if we invoke:
+#
+# make
+# # See "spatchCache.cacheWhenStderr" for why "--very-quiet" is
+# # used
+# make coccicheck SPATCH_FLAGS=--very-quiet
+#
+# We can with COMPUTE_HEADER_DEPENDENCIES (auto-detected as true with
+# "gcc" and "clang") write e.g. a .depend/grep.o.d for grep.c, when we
+# compile grep.o.
+#
+# The .depend/grep.o.d will have the full header dependency tree of
+# grep.c, and we can thus cache the output of "spatch" by:
+#
+# 1. Hashing all of those files
+# 2. Hashing our source file, and the *.cocci rule we're
+# applying
+# 3. Running spatch, if suggests no changes (by far the common
+# case) we invoke "spatchCache.getCmd" and
+# "spatchCache.setCmd" with a hash SHA-256 to ask "does this
+# ID have no changes" or "say that ID had no changes>
+# 4. If no "spatchCache.{set,get}Cmd" is specified we'll use
+# "redis-cli" and maintain a SET called "spatch-cache". Set
+# appropriate redis memory policies to keep it from growing
+# out of control.
+#
+# This along with the general incremental "make" support for
+# "contrib/coccinelle" makes it viable to (re-)run coccicheck
+# e.g. when merging integration branches.
+#
+# Note that the "--very-quiet" flag is currently critical. The cache
+# will refuse to cache anything that has output on STDERR (which might
+# be errors from spatch), but see spatchCache.cacheWhenStderr below.
+#
+# The STDERR (and exit code) could in principle be cached (as with
+# ccache), but then the simple structure in the Redis cache would need
+# to change, so just supply "--very-quiet" for now.
+#
+# To use this, simply set SPATCH to
+# contrib/coccinelle/spatchcache. Then optionally set:
+#
+# [spatchCache]
+# # Optional: path to a custom spatch
+# spatch = ~/g/coccicheck/spatch.opt
+#
+# As well as this trace config (debug implies trace):
+#
+# cacheWhenStderr = true
+# trace = false
+# debug = false
+#
+# The ".depend/grep.o.d" can also be customized, as a string that will
+# be eval'd, it has access to a "$dirname" and "$basename":
+#
+# [spatchCache]
+# dependFormat = "$dirname/.depend/${basename%.c}.o.d"
+#
+# Setting "trace" to "true" allows for seeing when we have a cache HIT
+# or MISS. To debug whether the cache is working do that, and run e.g.:
+#
+# redis-cli FLUSHALL
+# <make && make coccicheck, as above>
+# grep -hore HIT -e MISS -e SET -e NOCACHE -e CANTCACHE .build/contrib/coccinelle | sort | uniq -c
+# 600 CANTCACHE
+# 7365 MISS
+# 7365 SET
+#
+# A subsequent "make cocciclean && make coccicheck" should then have
+# all "HIT"'s and "CANTCACHE"'s.
+#
+# The "spatchCache.cacheWhenStderr" option is critical when using
+# spatchCache.{trace,debug} to debug whether something is set in the
+# cache, as we'll write to the spatch logs in .build/* we'd otherwise
+# always emit a NOCACHE.
+#
+# Reading the config can make the command much slower, to work around
+# this the config can be set in the environment, with environment
+# variable name corresponding to the config key. "default" can be used
+# to use whatever's the script default, e.g. setting
+# spatchCache.cacheWhenStderr=true and deferring to the defaults for
+# the rest is:
+#
+# export GIT_CONTRIB_SPATCHCACHE_DEBUG=default

+# bash/zsh completion support for core Git.
+#
+# Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
+# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
+# Distributed under the GNU General Public License, version 2.0.
+#
+# The contained completion routines provide support for completing:
+#
+# *) local and remote branch names
+# *) local and remote tag names
+# *) .git/remotes file names
+# *) git 'subcommands'
+# *) git email aliases for git-send-email
+# *) tree paths within 'ref:path/to/file' expressions
+# *) file paths within current working directory and index
+# *) common --long-options
+#
+# To use these routines:
+#
+# 1) Copy this file to somewhere (e.g. ~/.git-completion.bash).
+# 2) Add the following line to your .bashrc/.zshrc:
+# source ~/.git-completion.bash
+# 3) Consider changing your PS1 to also show the current branch,
+# see git-prompt.sh for details.
+#
+# If you use complex aliases of form '!f() { ... }; f', you can use the null
+# command ':' as the first command in the function body to declare the desired
+# completion style. For example '!f() { : git commit ; ... }; f' will
+# tell the completion to use commit completion. This also works with aliases
+# of form "!sh -c '...'". For example, "!sh -c ': git commit ; ... '".
+#
+# If you have a command that is not part of git, but you would still
+# like completion, you can use __git_complete:
+#
+# __git_complete gl git_log
+#
+# Or if it's a main command (i.e. git or gitk):
+#
+# __git_complete gk gitk
+#
+# Compatible with bash 3.2.57.
+#
+# You can set the following environment variables to influence the behavior of
+# the completion routines:
+#
+# GIT_COMPLETION_CHECKOUT_NO_GUESS
+#
+# When set to "1", do not include "DWIM" suggestions in git-checkout
+# and git-switch completion (e.g., completing "foo" when "origin/foo"
+# exists).
+#
+# GIT_COMPLETION_SHOW_ALL_COMMANDS
+#
+# When set to "1" suggest all commands, including plumbing commands
+# which are hidden by default (e.g. "cat-file" on "git ca<TAB>").
+#
+# GIT_COMPLETION_SHOW_ALL
+#
+# When set to "1" suggest all options, including options which are
+# typically hidden (e.g. '--allow-empty' for 'git commit').

+# Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
+# Distributed under the GNU General Public License, version 2.0.
+#
+# This script allows you to see repository status in your prompt.
+#
+# To enable:
+#
+# 1) Copy this file to somewhere (e.g. ~/.git-prompt.sh).
+# 2) Add the following line to your .bashrc/.zshrc:
+# source ~/.git-prompt.sh
+# 3a) Change your PS1 to call __git_ps1 as
+# command-substitution:
+# Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
+# ZSH: setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
+# the optional argument will be used as format string.
+# 3b) Alternatively, for a slightly faster prompt, __git_ps1 can
+# be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
+# with two parameters, <pre> and <post>, which are strings
+# you would put in $PS1 before and after the status string
+# generated by the git-prompt machinery. e.g.
+# Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
+# will show username, at-sign, host, colon, cwd, then
+# various status string, followed by dollar and SP, as
+# your prompt.
+# ZSH: precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
+# will show username, pipe, then various status string,
+# followed by colon, cwd, dollar and SP, as your prompt.
+# Optionally, you can supply a third argument with a printf
+# format string to finetune the output of the branch status
+#
+# The repository status will be displayed only if you are currently in a
+# git repository. The %s token is the placeholder for the shown status.
+#
+# The prompt status always includes the current branch name.
+#
+# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
+# unstaged (*) and staged (+) changes will be shown next to the branch
+# name. You can configure this per-repository with the
+# bash.showDirtyState variable, which defaults to true once
+# GIT_PS1_SHOWDIRTYSTATE is enabled.
+#
+# You can also see if currently something is stashed, by setting
+# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
+# then a '$' will be shown next to the branch name.
+#
+# If you would like to see if there're untracked files, then you can set
+# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
+# files, then a '%' will be shown next to the branch name. You can
+# configure this per-repository with the bash.showUntrackedFiles
+# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
+# enabled.
+#
+# If you would like to see the difference between HEAD and its upstream,
+# set GIT_PS1_SHOWUPSTREAM="auto". A "<" indicates you are behind, ">"
+# indicates you are ahead, "<>" indicates you have diverged and "="
+# indicates that there is no difference. You can further control
+# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
+# of values:
+#
+# verbose show number of commits ahead/behind (+/-) upstream
+# name if verbose, then also show the upstream abbrev name
+# legacy don't use the '--count' option available in recent
+# versions of git-rev-list
+# git always compare HEAD to @{upstream}
+# svn always compare HEAD to your SVN upstream
+#
+# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
+# find one, or @{upstream} otherwise. Once you have set
+# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
+# setting the bash.showUpstream config variable.
+#
+# You can change the separator between the branch name and the above
+# state symbols by setting GIT_PS1_STATESEPARATOR. The default separator
+# is SP.
+#
+# When there is an in-progress operation such as a merge, rebase,
+# revert, cherry-pick, or bisect, the prompt will include information
+# related to the operation, often in the form "|<OPERATION-NAME>".
+#
+# When the repository has a sparse-checkout, a notification of the form
+# "|SPARSE" will be included in the prompt. This can be shortened to a
+# single '?' character by setting GIT_PS1_COMPRESSSPARSESTATE, or omitted
+# by setting GIT_PS1_OMITSPARSESTATE.
+#
+# If you would like to see a notification on the prompt when there are
+# unresolved conflicts, set GIT_PS1_SHOWCONFLICTSTATE to "yes". The
+# prompt will include "|CONFLICT".
+#
+# If you would like to see more information about the identity of
+# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
+# to one of these values:
+#
+# contains relative to newer annotated tag (v1.6.3.2~35)
+# branch relative to newer tag or branch (master~4)
+# describe relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
+# tag relative to any older tag (v1.6.3.1-13-gdd42c2f)
+# default exactly matching tag
+#
+# If you would like a colored hint about the current dirty state, set
+# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
+# the colored output of "git status -sb" and are available only when
+# using __git_ps1 for PROMPT_COMMAND or precmd in Bash,
+# but always available in Zsh.
+#
+# If you would like __git_ps1 to do nothing in the case when the current
+# directory is set up to be ignored by git, then set
+# GIT_PS1_HIDE_IF_PWD_IGNORED to a nonempty value. Override this on the
+# repository level by setting bash.hideIfPwdIgnored to "false".

+===============
+
+NAME
+----
+git-contacts - List people who might be interested in a set of changes
+
+
+SYNOPSIS
+--------
+[verse]
+'git contacts' (<patch>|<range>|<rev>)...
+
+
+DESCRIPTION
+-----------
+
+Given a set of changes, specified as patch files or revisions, determine people
+who might be interested in those changes. This is done by consulting the
+history of each patch or revision hunk to find people mentioned by commits
+which touched the lines of files under consideration.
+
+Input consists of one or more patch files or revision arguments. A revision
+argument can be a range or a single `<rev>` which is interpreted as
+`<rev>..HEAD`, thus the same revision arguments are accepted as for
+linkgit:git-format-patch[1]. Patch files and revision arguments can be combined
+in the same invocation.
+
+This command can be useful for determining the list of people with whom to
+discuss proposed changes, or for finding the list of recipients to Cc: when
+submitting a patch series via `git send-email`. For the latter case, `git
+contacts` can be used as the argument to `git send-email`'s `--cc-cmd` option.
+
+
+DISCUSSION
+----------
+
+`git blame` is invoked for each hunk in a patch file or revision. For each
+commit mentioned by `git blame`, the commit message is consulted for people who
+authored, reviewed, signed, acknowledged, or were Cc:'d. Once the list of
+participants is known, each person's relevance is computed by considering how
+many commits mentioned that person compared with the total number of commits
+under consideration. The final output consists only of participants who exceed
+a minimum threshold of participation.
+
+
+OUTPUT
+------
+
+For each person of interest, a single line is output, terminated by a newline.
+If the person's name is known, ``Name $$<user@host>$$'' is printed; otherwise
+only ``$$<user@host>$$'' is printed.
+
+
+EXAMPLES
+--------
+
+* Consult patch files:
++
+------------
+$ git contacts feature/*.patch
+------------
+
+* Revision range:
++
+------------
+$ git contacts R1..R2
+------------
+
+* From a single revision to `HEAD`:
++
+------------
+$ git contacts origin
+------------
+
+* Helper for `git send-email`:
++
+------------
+$ git send-email --cc-cmd='git contacts' feature/*.patch
+------------
+
+
+LIMITATIONS
+-----------
+
+Several conditions controlling a person's significance are currently
+hard-coded, such as minimum participation level (10%), blame date-limiting (5
+years), and `-C` level for detecting moved and copied lines (a single `-C`). In
+the future, these conditions may become configurable.

+Version $VERSION by tzz\@lifelogs.com. License: BSD.
+
+Options:
+
+ -f|--file <authfile>: specify netrc-style files. Files with the .gpg
+ extension will be decrypted by GPG before parsing.
+ Multiple -f arguments are OK. They are processed in
+ order, and the first matching entry found is returned
+ via the credential helper protocol (see below).
+
+ When no -f option is given, .authinfo.gpg, .netrc.gpg,
+ .authinfo, and .netrc files in your home directory are
+ used in this order.
+
+ -g|--gpg <program> : specify the program for GPG. By default, this is the
+ value of gpg.program in the git repository or global
+ option or gpg.
+
+ -k|--insecure : ignore bad file ownership or permissions
+
+ -d|--debug : turn on debugging (developer info)
+
+ -v|--verbose : be more verbose (show files and information found)
+
+To enable this credential helper:
+
+ git config credential.helper '$shortname -f AUTHFILE1 -f AUTHFILE2'
+
+(Note that Git will prepend "git-credential-" to the helper name and look for it
+in the path.)
+
+...and if you want lots of debugging info:
+
+ git config credential.helper '$shortname -f AUTHFILE -d'
+
+...or to see the files opened and data found:
+
+ git config credential.helper '$shortname -f AUTHFILE -v'
+
+Only "get" mode is supported by this credential helper. It opens every
+<authfile> and looks for the first entry that matches the requested search
+criteria:
+
+ 'port|protocol':
+ The protocol that will be used (e.g., https). (protocol=X)
+
+ 'machine|host':
+ The remote hostname for a network credential. (host=X)
+
+ 'path':
+ The path with which the credential will be used. (path=X)
+
+ 'login|user|username':
+ The credential’s username, if we already have one. (username=X)
+
+Thus, when we get this query on STDIN:
+
+host=github.com
+protocol=https
+username=tzz
+
+this credential helper will look for the first entry in every <authfile> that
+matches
+
+machine github.com port https login tzz
+
+OR
+
+machine github.com protocol https login tzz
+
+OR... etc. acceptable tokens as listed above. Any unknown tokens are
+simply ignored.
+
+Then, the helper will print out whatever tokens it got from the entry, including
+"password" tokens, mapping back to Git's helper protocol; e.g. "port" is mapped
+back to "protocol". Any redundant entry tokens (part of the original query) are
+skipped.
+
+Again, note that only the first matching entry from all the <authfile>s,
+processed in the sequence given on the command line, is used.
+
+Netrc/authinfo tokens can be quoted as 'STRING' or "STRING".
+
+No caching is performed by this credential helper.

+diff-highlight
+==============
+
+Line oriented diffs are great for reviewing code, because for most
+hunks, you want to see the old and the new segments of code next to each
+other. Sometimes, though, when an old line and a new line are very
+similar, it's hard to immediately see the difference.
+
+You can use "--color-words" to highlight only the changed portions of
+lines. However, this can often be hard to read for code, as it loses
+the line structure, and you end up with oddly formatted bits.
+
+Instead, this script post-processes the line-oriented diff, finds pairs
+of lines, and highlights the differing segments. It's currently very
+simple and stupid about doing these tasks. In particular:
+
+ 1. It will only highlight hunks in which the number of removed and
+ added lines is the same, and it will pair lines within the hunk by
+ position (so the first removed line is compared to the first added
+ line, and so forth). This is simple and tends to work well in
+ practice. More complex changes don't highlight well, so we tend to
+ exclude them due to the "same number of removed and added lines"
+ restriction. Or even if we do try to highlight them, they end up
+ not highlighting because of our "don't highlight if the whole line
+ would be highlighted" rule.
+
+ 2. It will find the common prefix and suffix of two lines, and
+ consider everything in the middle to be "different". It could
+ instead do a real diff of the characters between the two lines and
+ find common subsequences. However, the point of the highlight is to
+ call attention to a certain area. Even if some small subset of the
+ highlighted area actually didn't change, that's OK. In practice it
+ ends up being more readable to just have a single blob on the line
+ showing the interesting bit.
+
+The goal of the script is therefore not to be exact about highlighting
+changes, but to call attention to areas of interest without being
+visually distracting. Non-diff lines and existing diff coloration is
+preserved; the intent is that the output should look exactly the same as
+the input, except for the occasional highlight.
+
+Use
+---
+
+You can try out the diff-highlight program with:
+
+---------------------------------------------
+git log -p --color | /path/to/diff-highlight
+---------------------------------------------
+
+If you want to use it all the time, drop it in your $PATH and put the
+following in your git configuration:
+
+---------------------------------------------
+[pager]
+ log = diff-highlight | less
+ show = diff-highlight | less
+ diff = diff-highlight | less
+---------------------------------------------
+
+
+Color Config
+------------
+
+You can configure the highlight colors and attributes using git's
+config. The colors for "old" and "new" lines can be specified
+independently. There are two "modes" of configuration:
+
+ 1. You can specify a "highlight" color and a matching "reset" color.
+ This will retain any existing colors in the diff, and apply the
+ "highlight" and "reset" colors before and after the highlighted
+ portion.
+
+ 2. You can specify a "normal" color and a "highlight" color. In this
+ case, existing colors are dropped from that line. The non-highlighted
+ bits of the line get the "normal" color, and the highlights get the
+ "highlight" color.
+
+If no "new" colors are specified, they default to the "old" colors. If
+no "old" colors are specified, the default is to reverse the foreground
+and background for highlighted portions.
+
+Examples:
+
+---------------------------------------------
+# Underline highlighted portions
+[color "diff-highlight"]
+oldHighlight = ul
+oldReset = noul
+---------------------------------------------
+
+---------------------------------------------
+# Varying background intensities
+[color "diff-highlight"]
+oldNormal = "black #f8cbcb"
+oldHighlight = "black #ffaaaa"
+newNormal = "black #cbeecb"
+newHighlight = "black #aaffaa"
+---------------------------------------------
+
+
+Using diff-highlight as a module
+--------------------------------
+
+If you want to pre- or post- process the highlighted lines as part of
+another perl script, you can use the DiffHighlight module. You can
+either "require" it or just cat the module together with your script (to
+avoid run-time dependencies).
+
+Your script may set up one or more of the following variables:
+
+ - $DiffHighlight::line_cb - this should point to a function which is
+ called whenever DiffHighlight has lines (which may contain
+ highlights) to output. The default function prints each line to
+ stdout. Note that the function may be called with multiple lines.
+
+ - $DiffHighlight::flush_cb - this should point to a function which
+ flushes the output (because DiffHighlight believes it has completed
+ processing a logical chunk of input). The default function flushes
+ stdout.
+
+The script may then feed lines, one at a time, to DiffHighlight::handle_line().
+When lines are done processing, they will be fed to $line_cb. Note that
+DiffHighlight may queue up many input lines (to analyze a whole hunk)
+before calling $line_cb. After providing all lines, call
+DiffHighlight::flush() to flush any unprocessed lines.
+
+If you just want to process stdin, DiffHighlight::highlight_stdin()
+is a convenience helper which will loop and flush for you.
+
+
+Bugs
+----
+
+Because diff-highlight relies on heuristics to guess which parts of
+changes are important, there are some cases where the highlighting is
+more distracting than useful. Fortunately, these cases are rare in
+practice, and when they do occur, the worst case is simply a little
+extra highlighting. This section documents some cases known to be
+sub-optimal, in case somebody feels like working on improving the
+heuristics.
+
+1. Two changes on the same line get highlighted in a blob. For example,
+ highlighting:
+
+----------------------------------------------
+-foo(buf, size);
++foo(obj->buf, obj->size);
+----------------------------------------------
+
+ yields (where the inside of "+{}" would be highlighted):
+
+----------------------------------------------
+-foo(buf, size);
++foo(+{obj->buf, obj->}size);
+----------------------------------------------
+
+ whereas a more semantically meaningful output would be:
+
+----------------------------------------------
+-foo(buf, size);
++foo(+{obj->}buf, +{obj->}size);
+----------------------------------------------
+
+ Note that doing this right would probably involve a set of
+ content-specific boundary patterns, similar to word-diff. Otherwise
+ you get junk like:
+
+-----------------------------------------------------
+-this line has some -{i}nt-{ere}sti-{ng} text on it
++this line has some +{fa}nt+{a}sti+{c} text on it
+-----------------------------------------------------
+
+ which is less readable than the current output.
+
+2. The multi-line matching assumes that lines in the pre- and post-image
+ match by position. This is often the case, but can be fooled when a
+ line is removed from the top and a new one added at the bottom (or
+ vice versa). Unless the lines in the middle are also changed, diffs
+ will show this as two hunks, and it will not get highlighted at all
+ (which is good). But if the lines in the middle are changed, the
+ highlighting can be misleading. Here's a pathological case:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two 2
++three 3
++four 4
++five 5
+-----------------------------------------------------
+
+ which gets highlighted as:
+
+-----------------------------------------------------
+-one
+-t-{wo}
+-three
+-f-{our}
++two 2
++t+{hree 3}
++four 4
++f+{ive 5}
+-----------------------------------------------------
+
+ because it matches "two" to "three 3", and so forth. It would be
+ nicer as:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two +{2}
++three +{3}
++four +{4}
++five 5
+-----------------------------------------------------
+
+ which would probably involve pre-matching the lines into pairs
+ according to some heuristic.

+
+Other things that can be useful:

+=head1 NAME
+
+import-directories - Import bits and pieces to Git.
+
+=head1 SYNOPSIS
+
+B<import-directories.perl> F<configfile> F<outputfile>
+
+=head1 DESCRIPTION
+
+Script to import arbitrary projects version controlled by the "copy the
+source directory to a new location and edit it there"-version controlled
+projects into version control. Handles projects with arbitrary branching
+and version trees, taking a file describing the inputs and generating a
+file compatible with the L<git-fast-import(1)> format.
+
+=head1 CONFIGURATION FILE
+
+=head2 Format
+
+The configuration file is based on the standard I<.ini> format.
+
+ ; Comments start with semi-colons
+ [section]
+ key=value
+
+Please see below for information on how to escape special characters.
+
+=head2 Global configuration
+
+Global configuration is done in the B<[config]> section, which should be
+the first section in the file. Configuration can be changed by
+repeating configuration sections later on.
+
+ [config]
+ ; configure conversion of CRLFs. "convert" means that all CRLFs
+ ; should be converted into LFs (suitable for the core.autocrlf
+ ; setting set to true in Git). "none" means that all data is
+ ; treated as binary.
+ crlf=convert
+
+=head2 Revision configuration
+
+Each revision that is to be imported is described in three
+sections. Revisions should be defined in topological order, so
+that a revision's parent has always been defined when a new revision
+is introduced. All the sections for one revision must be defined
+before defining the next revision.
+
+Each revision is assigned a unique numerical identifier. The
+numbers do not need to be consecutive, nor monotonically
+increasing.
+
+For instance, if your configuration file contains only the two
+revisions 4711 and 42, where 4711 is the initial commit, the
+only requirement is that 4711 is completely defined before 42.
+
+=pod
+
+=head3 Revision description section
+
+A section whose section name is just an integer gives meta-data
+about the revision.
+
+ [3]
+ ; author sets the author of the revisions
+ author=Peter Krefting <peter@softwolves.pp.se>
+ ; branch sets the branch that the revision should be committed to
+ branch=master
+ ; parent describes the revision that is the parent of this commit
+ ; (optional)
+ parent=1
+ ; merges describes a revision that is merged into this commit
+ ; (optional; can be repeated)
+ merges=2
+ ; selects one file to take the timestamp from
+ ; (optional; if unspecified, the most recent file from the .files
+ ; section is used)
+ timestamp=3/source.c
+
+=head3 Revision contents section
+
+A section whose section name is an integer followed by B<.files>
+describe all the files included in this revision. If a file that
+was available previously is not included in this revision, it will
+be removed.
+
+If an on-disk revision is incomplete, you can point to files from
+a previous revision. There are no restrictions on where the source
+files are located, nor on their names.
+
+ [3.files]
+ ; the key is the path inside the repository, the value is the path
+ ; as seen from the importer script.
+ source.c=ver-3.00/source.c
+ source.h=ver-2.99/source.h
+ readme.txt=ver-3.00/introduction to the project.txt
+
+File names are treated as byte strings (but please see below on
+quoting rules), and should be stored in the configuration file in
+the encoding that should be used in the generated repository.
+
+=head3 Revision commit message section
+
+A section whose section name is an integer followed by B<.message>
+gives the commit message. This section is read verbatim, up until
+the beginning of the next section. As such, a commit message may not
+contain a line that begins with an opening square bracket ("[") and
+ends with a closing square bracket ("]"), unless they are surrounded
+by whitespace or other characters.
+
+ [3.message]
+ Implement foobar.
+ ; trailing blank lines are ignored.

+=head2 Escaping special characters
+
+Key and value strings may be enclosed in quotes, in which case
+whitespace inside the quotes is preserved. Additionally, an equal
+sign may be included in the key by preceding it with a backslash.
+For example:
+
+ "key1 "=value1
+ key2=" value2"
+ key\=3=value3
+ key4=value=4
+ "key5""=value5
+
+Here the first key is "key1 " (note the trailing white-space) and the
+second value is " value2" (note the leading white-space). The third
+key contains an equal sign "key=3" and so does the fourth value, which
+does not need to be escaped. The fifth key contains a trailing quote,
+which does not need to be escaped since it is inside a surrounding
+quote.
+
+=cut
+ my $pair = shift;
+
+ # Separate key and value by the first non-quoted equal sign
+ my ($key, $value);
+ if ($pair =~ /^(.*[^\\])=(.*)$/)

+ die "Parse error: $pair\n ";

+
+ # Unquote and unescape the key and value separately
+ return (&unescape($key), &unescape($value));
+}
+
+# Unquote and unescape
+sub unescape
+{
+ my $string = shift;
+
+ # First remove enclosing quotes. Backslash before the trailing
+ # quote leaves both.
+ if ($string =~ /^"(.*[^\\])"$/)
+ {
+ $string = $1;
+ }
+
+ # Second remove any backslashes inside the unquoted string.
+ # For later: Handle special sequences like \t ?

+git-jump
+========
+
+Git-jump is a script for helping you jump to "interesting" parts of your
+project in your editor. It works by outputting a set of interesting
+spots in the "quickfix" format, which editors like vim can use as a
+queue of places to visit (this feature is usually used to jump to errors
+produced by a compiler). For example, given a diff like this:
+
+------------------------------------
+diff --git a/foo.c b/foo.c
+index a655540..5a59044 100644
+--- a/foo.c
++++ b/foo.c
+@@ -1,3 +1,3 @@
+ int main(void) {
+- printf("hello word!\n");
++ printf("hello world!\n");
+ }
+-----------------------------------
+
+git-jump will feed this to the editor:
+
+-----------------------------------
+foo.c:2: printf("hello word!\n");
+-----------------------------------
+
+Or, when running 'git jump grep', column numbers will also be emitted,
+e.g. `git jump grep "hello"` would return:
+
+-----------------------------------
+foo.c:2:9: printf("hello word!\n");
+-----------------------------------
+
+Obviously this trivial case isn't that interesting; you could just open
+`foo.c` yourself. But when you have many changes scattered across a
+project, you can use the editor's support to "jump" from point to point.
+
+Git-jump can generate four types of interesting lists:
+
+ 1. The beginning of any diff hunks.
+
+ 2. The beginning of any merge conflict markers.
+
+ 3. Any grep matches, including the column of the first match on a
+ line.
+
+ 4. Any whitespace errors detected by `git diff --check`.
+
+
+Using git-jump
+--------------
+
+To use it, just drop git-jump in your PATH, and then invoke it like
+this:
+
+--------------------------------------------------
+# jump to changes not yet staged for commit
+git jump diff
+
+# jump to changes that are staged for commit; you can give
+# arbitrary diff options
+git jump diff --cached
+
+# jump to merge conflicts
+git jump merge
+
+# documentation conflicts are hard; skip past them for now
+git jump merge :^Documentation
+
+# jump to all instances of foo_bar
+git jump grep foo_bar
+
+# same as above, but case-insensitive; you can give
+# arbitrary grep options
+git jump grep -i foo_bar
+
+# use the silver searcher for git jump grep
+git config jump.grepCmd "ag --column"
+--------------------------------------------------
+
+
+Related Programs
+----------------
+
+You can accomplish some of the same things with individual tools. For
+example, you can use `git mergetool` to start vimdiff on each unmerged
+file. `git jump merge` is for the vim-wielding luddite who just wants to
+jump straight to the conflict text with no fanfare.
+
+As of git v1.7.2, `git grep` knows the `--open-files-in-pager` option,
+which does something similar to `git jump grep`. However, it is limited
+to positioning the cursor to the correct line in only the first file,
+leaving you to locate subsequent hits in that file or other files using
+the editor or pager. By contrast, git-jump provides the editor with a
+complete list of files, lines, and a column number for each match.
+
+
+Limitations
+-----------
+
+This script was written and tested with vim. Given that the quickfix
+format is the same as what gcc produces, I expect emacs users have a
+similar feature for iterating through the list, but I know nothing about
+how to activate it.
+
+The shell snippets to generate the quickfix lines will almost certainly
+choke on filenames with exotic characters (like newlines).
+
+Contributing
+------------
+
+Bug fixes, bug reports, and feature requests should be discussed on the
+Git mailing list <git@vger.kernel.org>, and cc'd to the git-jump
+maintainer, Jeff King <peff@peff.net>.

+hg-to-git.py is able to convert a Mercurial repository into a git one,
+and preserves the branches in the process (unlike tailor)
+
+hg-to-git.py can probably be greatly improved (it's a rather crude
+combination of shell and python) but it does already work quite well for
+me. Features:
+ - supports incremental conversion
+ (for keeping a git repo in sync with a hg one)
+ - supports hg branches
+ - converts hg tags
+
+Note that the git repository will be created 'in place' (at the same
+location as the source hg repo). You will have to manually remove the
+'.hg' directory after the conversion.
+
+Also note that the incremental conversion uses 'simple' hg changesets
+identifiers (ordinals, as opposed to SHA-1 ids), and since these ids
+are not stable across different repositories the hg-to-git.py state file
+is forever tied to one hg repository.

+#!/bin/sh
+#
+# Copyright (c) 2007 Andy Parkins
+#
+# An example hook script to mail out commit update information.
+#
+# NOTE: This script is no longer under active development. There
+# is another script, git-multimail, which is more capable and
+# configurable and is largely backwards-compatible with this script;
+# please see "contrib/hooks/multimail/". For instructions on how to
+# migrate from post-receive-email to git-multimail, please see
+# "README.migrate-from-post-receive-email" in that directory.
+#
+# This hook sends emails listing new revisions to the repository
+# introduced by the change being reported. The rule is that (for
+# branch updates) each commit will appear on one email and one email
+# only.
+#
+# This hook is stored in the contrib/hooks directory. Your distribution
+# will have put this somewhere standard. You should make this script
+# executable then link to it in the repository you would like to use it in.
+# For example, on debian the hook is stored in
+# /usr/share/git-core/contrib/hooks/post-receive-email:
+#
+# cd /path/to/your/repository.git
+# ln -sf /usr/share/git-core/contrib/hooks/post-receive-email hooks/post-receive
+#
+# This hook script assumes it is enabled on the central repository of a
+# project, with all users pushing only to it and not between each other. It
+# will still work if you don't operate in that style, but it would become
+# possible for the email to be from someone other than the person doing the
+# push.
+#
+# To help with debugging and use on pre-v1.5.1 git servers, this script will
+# also obey the interface of hooks/update, taking its arguments on the
+# command line. Unfortunately, hooks/update is called once for each ref.
+# To avoid firing one email per ref, this script just prints its output to
+# the screen when used in this mode. The output can then be redirected if
+# wanted.
+#
+# Config
+# ------
+# hooks.mailinglist
+# This is the list that all pushes will go to; leave it blank to not send
+# emails for every ref update.
+# hooks.announcelist
+# This is the list that all pushes of annotated tags will go to. Leave it
+# blank to default to the mailinglist field. The announce emails lists
+# the short log summary of the changes since the last annotated tag.
+# hooks.envelopesender
+# If set then the -f option is passed to sendmail to allow the envelope
+# sender address to be set
+# hooks.emailprefix
+# All emails have their subjects prefixed with this prefix, or "[SCM]"
+# if emailprefix is unset, to aid filtering
+# hooks.showrev
+# The shell command used to format each revision in the email, with
+# "%s" replaced with the commit id. Defaults to "git rev-list -1
+# --pretty %s", displaying the commit id, author, date and log
+# message. To list full patches separated by a blank line, you
+# could set this to "git show -C %s; echo".
+# To list a gitweb/cgit URL *and* a full patch for each change set, use this:
+# "t=%s; printf 'http://.../?id=%%s' \$t; echo;echo; git show -C \$t; echo"
+# Be careful if "..." contains things that will be expanded by shell "eval"
+# or printf.
+# hooks.emailmaxlines
+# The maximum number of lines that should be included in the generated
+# email body. If not specified, there is no limit.
+# Lines beyond the limit are suppressed and counted, and a final
+# line is added indicating the number of suppressed lines.
+# hooks.diffopts
+# Alternate options for the git diff-tree invocation that shows changes.
+# Default is "--stat --summary --find-copies-harder". Add -p to those
+# options to include a unified diff of changes in addition to the usual
+# summary output.
+#
+# Notes
+# -----
+# All emails include the headers "X-Git-Refname", "X-Git-Oldrev",
+# "X-Git-Newrev", and "X-Git-Reftype" to enable fine tuned filtering and
+# give information for debugging.

+ # In this case we want to issue an email containing only revisions
+ # 3, 4, and N. Given (almost) by
+ #
+ # git rev-list N ^O --not --all
+ #
+ # The reason for the "almost", is that the "--not --all" will take
+ # precedence over the "N", and effectively will translate to
+ #
+ # git rev-list N ^O ^X ^N
+ #
+ # So, we need to build up the list more carefully. git rev-parse
+ # will generate a list of revs that may be fed into git rev-list.
+ # We can get it to make the "--not --all" part and then filter out
+ # the "^N" with:
+ #
+ # git rev-parse --not --all | grep -v N
+ #
+ # Then, using the --stdin switch to git rev-list we have effectively
+ # manufactured
+ #
+ # git rev-list N ^O ^X
+ #
+ # This leaves a problem when someone else updates the repository
+ # while this script is running. Their new value of the ref we're
+ # working on would be included in the "--not --all" output; and as
+ # our $newrev would be an ancestor of that commit, it would exclude
+ # all of our commits. What we really want is to exclude the current
+ # value of $refname from the --not list, rather than N itself. So:
+ #
+ # git rev-parse --not --all | grep -v $(git rev-parse $refname)
+ #
+ # Gets us to something pretty safe (apart from the small time
+ # between refname being read, and git rev-parse running - for that,
+ # I give up)
+ #
+ #
+ # Next problem, consider this:
+ # * --- B --- * --- O ($oldrev)
+ # \
+ # * --- X --- * --- N ($newrev)
+ #
+ # That is to say, there is no guarantee that oldrev is a strict
+ # subset of newrev (it would have required a --force, but that's
+ # allowed). So, we can't simply say rev-list $oldrev..$newrev.
+ # Instead we find the common base of the two revs and list from
+ # there.
+ #
+ # As above, we need to take into account the presence of X; if
+ # another branch is already in the repository and points at some of
+ # the revisions that we are about to output - we don't want them.
+ # The solution is as before: git rev-parse output filtered.
+ #
+ # Finally, tags: 1 --- 2 --- O --- T --- 3 --- 4 --- N
+ #
+ # Tags pushed into the repository generate nice shortlog emails that
+ # summarise the commits between them and the previous tag. However,
+ # those emails don't include the full commit messages that we output
+ # for a branch update. Therefore we still want to output revisions
+ # that have been output on a tag email.
+ #
+ # Luckily, git rev-parse includes just the tool. Instead of using
+ # "--all" we use "--branches"; this has the added benefit that
+ # "remotes/" will be ignored as well.
+
+ # List all of the revisions that were removed by this update, in a

+Invoked as: update refname old-sha1 new-sha1
+
+This script is run by git-receive-pack once for each ref that the
+client is trying to modify. If we exit with a non-zero exit value
+then the update for that particular ref is denied, but updates for
+other refs in the same run of receive-pack may still be allowed.
+
+We are run after the objects have been uploaded, but before the
+ref is actually modified. We take advantage of that fact when we
+look for "new" commits and tags (the new objects won't show up in
+`rev-list --all`).
+
+This script loads and parses the content of the config file
+"users/$this_user.acl" from the $acl_branch commit of $acl_git ODB.
+The acl file is a git-config style file, but uses a slightly more
+restricted syntax as the Perl parser contained within this script
+is not nearly as permissive as git-config.
+
+Example:
+
+ [user]
+ committer = John Doe <john.doe@example.com>
+ committer = John R. Doe <john.doe@example.com>
+
+ [repository "acls"]
+ allow = heads/master
+ allow = CDUR for heads/jd/
+ allow = C for ^tags/v\\d+$
+
+For all new commit or tag objects the committer (or tagger) line
+within the object must exactly match one of the user.committer
+values listed in the acl file ("HEAD:users/$this_user.acl").
+
+For a branch to be modified an allow line within the matching
+repository section must be matched for both the refname and the
+opcode.
+
+Repository sections are matched on the basename of the repository
+(after removing the .git suffix).
+
+The opcode abbreviations are:
+
+ C: create new ref
+ D: delete existing ref
+ U: fast-forward existing ref (no commit loss)
+ R: rewind/rebase existing ref (commit loss)
+
+if no opcodes are listed before the "for" keyword then "U" (for
+fast-forward update only) is assumed as this is the most common
+usage.
+
+Refnames are matched by always assuming a prefix of "refs/".
+This hook forbids pushing or deleting anything not under "refs/".
+
+Refnames that start with ^ are Perl regular expressions, and the ^
+is kept as part of the regexp. \\ is needed to get just one \, so
+\\d expands to \d in Perl. The 3rd allow line above is an example.
+
+Refnames that don't start with ^ but that end with / are prefix
+matches (2nd allow line above); all other refnames are strict
+equality matches (1st allow line).
+
+Anything pushed to "heads/" (ok, really "refs/heads/") must be
+a commit. Tags are not permitted here.
+
+Anything pushed to "tags/" (err, really "refs/tags/") must be an
+annotated tag. Commits, blobs, trees, etc. are not permitted here.
+Annotated tag signatures aren't checked, nor are they required.
+
+The special subrepository of 'info/new-commit-check' can
+be created and used to allow users to push new commits and
+tags from another local repository to this one, even if they
+aren't the committer/tagger of those objects. In a nut shell
+the info/new-commit-check directory is a Git repository whose
+objects/info/alternates file lists this repository and all other
+possible sources, and whose refs subdirectory contains symlinks
+to this repository's refs subdirectory, and to all other possible
+sources refs subdirectories. Yes, this means that you cannot
+use packed-refs in those repositories as they won't be resolved
+correctly.

+USAGE: git mw preview [--remote|-r <remote name>] [--autoload|-a]
+ [--output|-o <output filename>] [--verbose|-v]
+ <blob> | <filename>
+
+DESCRIPTION:
+Preview is an utiliy to preview local content of a mediawiki repo as if it was
+pushed on the remote.
+
+For that, preview searches for the remote name of the current branch's
+upstream if --remote is not set. If that remote is not found or if it
+is not a mediawiki, it lists all mediawiki remotes configured and asks
+you to replay your command with the --remote option set properly.
+
+Then, it searches for a file named 'filename'. If it's not found in
+the current dir, it will assume it's a blob.
+
+The content retrieved in the file (or in the blob) will then be parsed
+by the remote mediawiki and combined with a template retrieved from
+the mediawiki.
+
+Finally, preview will save the HTML result in a file. and autoload it
+in your default web browser if the option --autoload is present.
+
+OPTIONS:
+ -r <remote name>, --remote <remote name>
+ If the remote is a mediawiki, the template and the parse engine
+ used for the preview will be those of that remote.
+ If not, a list of valid remotes will be shown.
+
+ -a, --autoload
+ Try to load the HTML output in a new tab (or new window) of your
+ default web browser.
+
+ -o <output filename>, --output <output filename>
+ Change the HTML output filename. Default filename is based on the
+ input filename with its extension replaced by '.html'.
+
+ -v, --verbose
+ Show more information on what's going on under the hood.

+Tests for Mediawiki-to-Git
+==========================
+
+Introduction
+------------
+This manual describes how to install the git-remote-mediawiki test
+environment on a machine with git installed on it.
+
+Prerequisite
+------------
+
+In order to run this test environment correctly, you will need to
+install the following packages (Debian/Ubuntu names, may need to be
+adapted for another distribution):
+
+* lighttpd
+* php
+* php-cgi
+* php-cli
+* php-curl
+* php-sqlite
+
+Principles and Technical Choices
+--------------------------------
+
+The test environment makes it easy to install and manipulate one or
+several MediaWiki instances. To allow developers to run the testsuite
+easily, the environment does not require root privilege (except to
+install the required packages if needed). It starts a webserver
+instance on the user's account (using lighttpd greatly helps for
+that), and does not need a separate database daemon (thanks to the use
+of sqlite).
+
+Run the test environment
+------------------------
+
+Install a new wiki
+~~~~~~~~~~~~~~~~~~
+
+Once you have all the prerequisite, you need to install a MediaWiki
+instance on your machine. If you already have one, it is still
+strongly recommended to install one with the script provided. Here's
+how to work it:
+
+a. change directory to contrib/mw-to-git/t/
+b. if needed, edit test.config to choose your installation parameters
+c. run `./install-wiki.sh install`
+d. check on your favourite web browser if your wiki is correctly
+ installed.
+
+Remove an existing wiki
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Edit the file test.config to fit the wiki you want to delete, and then
+execute the command `./install-wiki.sh delete` from the
+contrib/mw-to-git/t directory.
+
+Run the existing tests
+~~~~~~~~~~~~~~~~~~~~~~
+
+The provided tests are currently in the `contrib/mw-to-git/t` directory.
+The files are all the t936[0-9]-*.sh shell scripts.
+
+a. Run all tests:
+To do so, run "make test" from the contrib/mw-to-git/ directory.
+
+b. Run a specific test:
+To run a given test <test_name>, run ./<test_name> from the
+contrib/mw-to-git/t directory.
+
+How to create new tests
+-----------------------
+
+Available functions
+~~~~~~~~~~~~~~~~~~~
+
+The test environment of git-remote-mediawiki provides some functions
+useful to test its behaviour. for more details about the functions'
+parameters, please refer to the `test-gitmw-lib.sh` and
+`test-gitmw.pl` files.
+
+** `test_check_wiki_precond`:
+Check if the tests must be skipped or not. Please use this function
+at the beginning of each new test file.
+
+** `wiki_getpage`:
+Fetch a given page from the wiki and puts its content in the
+directory in parameter.
+
+** `wiki_delete_page`:
+Delete a given page from the wiki.
+
+** `wiki_edit_page`:
+Create or modify a given page in the wiki. You can specify several
+parameters like a summary for the page edition, or add the page to a
+given category.
+See test-gitmw.pl for more details.
+
+** `wiki_getallpage`:
+Fetch all pages from the wiki into a given directory. The directory
+is created if it does not exists.
+
+** `test_diff_directories`:
+Compare the content of two directories. The content must be the same.
+Use this function to compare the content of a git directory and a wiki
+one created by wiki_getallpage.
+
+** `test_contains_N_files`:
+Check if the given directory contains a given number of file.
+
+** `wiki_page_exists`:
+Tests if a given page exists on the wiki.
+
+** `wiki_reset`:
+Reset the wiki, i.e. flush the database. Use this function at the
+beginning of each new test, except if the test re-uses the same wiki
+(and history) as the previous test.
+
+How to write a new test
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Please, follow the standards given by git. See git/t/README.
+New file should be named as t936[0-9]-*.sh.
+Be sure to reset your wiki regularly with the function `wiki_reset`.

+git-remote-persistent-https
+
+The git-remote-persistent-https binary speeds up SSL operations
+by running a daemon job (git-remote-persistent-https--proxy) that
+keeps a connection open to a server.
+
+
+PRE-BUILT BINARIES
+
+Darwin amd64:
+https://commondatastorage.googleapis.com/git-remote-persistent-https/darwin_amd64.tar.gz
+
+Linux amd64:
+https://commondatastorage.googleapis.com/git-remote-persistent-https/linux_amd64.tar.gz
+
+
+INSTALLING
+
+Move all of the git-remote-persistent-http* binaries to a directory
+in PATH.
+
+
+USAGE
+
+HTTPS requests can be delegated to the proxy by using the
+"persistent-https" scheme, e.g.
+
+git clone persistent-https://kernel.googlesource.com/pub/scm/git/git
+
+Likewise, .gitconfig can be updated as follows to rewrite https urls
+to use persistent-https:
+
+[url "persistent-https"]
+ insteadof = https
+[url "persistent-http"]
+ insteadof = http
+
+You may also want to allow the use of the persistent-https helper for
+submodule URLs (since any https URLs pointing to submodules will be
+rewritten, and Git's out-of-the-box defaults forbid submodules from
+using unknown remote helpers):
+
+[protocol "persistent-https"]
+ allow = always
+[protocol "persistent-http"]
+ allow = always
+
+
+#####################################################################
+# BUILDING FROM SOURCE
+#####################################################################
+
+LOCATION
+
+The source is available in the contrib/persistent-https directory of
+the Git source repository. The Git source repository is available at
+git://git.kernel.org/pub/scm/git/git.git/
+https://kernel.googlesource.com/pub/scm/git/git
+
+
+PREREQUISITES
+
+The code is written in Go (http://golang.org/) and the Go compiler is
+required. Currently, the compiler must be built and installed from tip
+of source, in order to include a fix in the reverse http proxy:
+http://code.google.com/p/go/source/detail?r=a615b796570a2cd8591884767a7d67ede74f6648
+
+
+BUILDING
+
+Run "make" to build the binaries. See the section on
+INSTALLING above.

+# This tool will print vaguely pretty information about a pack. It
+# expects the output of "git verify-pack -v" as input on stdin.
+#
+# $ git verify-pack -v | packinfo.pl
+#
+# This prints some full-pack statistics; currently "all sizes", "all
+# path sizes", "tree sizes", "tree path sizes", and "depths".
+#
+# * "all sizes" stats are across every object size in the file;
+# full sizes for base objects, and delta size for deltas.
+# * "all path sizes" stats are across all object's "path sizes".
+# A path size is the sum of the size of the delta chain, including the
+# base object. In other words, it's how many bytes need be read to
+# reassemble the file from deltas.
+# * "tree sizes" are object sizes grouped into delta trees.
+# * "tree path sizes" are path sizes grouped into delta trees.
+# * "depths" should be obvious.
+#
+# When run as:
+#
+# $ git verify-pack -v | packinfo.pl -tree
+#

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by

+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of

+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may

+HOW TO INSTALL git-subtree
+==========================
+
+First, build from the top source directory.
+
+Then, in contrib/subtree, run:
+
+ make
+ make install
+ make install-doc
+
+If you used configure to do the main build the git-subtree build will
+pick up those settings. If not, you will likely have to provide a
+value for prefix:
+
+ make prefix=<some dir>
+ make prefix=<some dir> install
+ make prefix=<some dir> install-doc
+
+To run tests first copy git-subtree to the main build area so the
+newly-built git can find it:
+
+ cp git-subtree ../..
+
+Then:
+
+ make test

+
+DESCRIPTION
+-----------
+Subtrees allow subprojects to be included within a subdirectory
+of the main project, optionally including the subproject's
+entire history.
+
+For example, you could include the source code for a library
+as a subdirectory of your application.
+
+Subtrees are not to be confused with submodules, which are meant for
+the same task. Unlike submodules, subtrees do not need any special
+constructions (like '.gitmodules' files or gitlinks) be present in
+your repository, and do not force end-users of your
+repository to do anything special or to understand how subtrees
+work. A subtree is just a subdirectory that can be
+committed to, branched, and merged along with your project in
+any way you want.
+
+They are also not to be confused with using the subtree merge
+strategy. The main difference is that, besides merging
+the other project as a subdirectory, you can also extract the
+entire history of a subdirectory from your project and make it
+into a standalone project. Unlike the subtree merge strategy
+you can alternate back and forth between these
+two operations. If the standalone library gets updated, you can
+automatically merge the changes into your project; if you
+update the library inside your project, you can "split" the
+changes back out again and merge them back into the library
+project.
+
+For example, if a library you made for one application ends up being
+useful elsewhere, you can extract its entire history and publish
+that as its own git repository, without accidentally
+intermingling the history of your application project.
+
+[TIP]
+In order to keep your commit messages clean, we recommend that
+people split their commits between the subtrees and the main
+project as much as possible. That is, if you make a change that
+affects both the library and the main application, commit it in
+two pieces. That way, when you split the library commits out
+later, their descriptions will still make sense. But if this
+isn't important to you, it's not *necessary*. 'git subtree' will
+simply leave out the non-library-related parts of the commit
+when it splits it out into the subproject later.
+
+
+COMMANDS
+--------
+add <local-commit>::
+add <repository> <remote-ref>::
+ Create the <prefix> subtree by importing its contents
+ from the given <local-commit> or <repository> and <remote-ref>.
+ A new commit is created automatically, joining the imported
+ project's history with your own. With '--squash', import
+ only a single commit from the subproject, rather than its
+ entire history.
+
+merge <local-commit> [<repository>]::
+ Merge recent changes up to <local-commit> into the <prefix>
+ subtree. As with normal 'git merge', this doesn't
+ remove your own local changes; it just merges those
+ changes into the latest <local-commit>. With '--squash',
+ create only one commit that contains all the changes,
+ rather than merging in the entire history.
++
+If you use '--squash', the merge direction doesn't always have to be
+forward; you can use this command to go back in time from v2.5 to v2.4,
+for example. If your merge introduces a conflict, you can resolve it in
+the usual ways.
++
+When using '--squash', and the previous merge with '--squash' merged an
+annotated tag of the subtree repository, that tag needs to be available locally.
+If <repository> is given, a missing tag will automatically be fetched from that
+repository.
+
+split [<local-commit>] [<repository>]::
+ Extract a new, synthetic project history from the
+ history of the <prefix> subtree of <local-commit>, or of
+ HEAD if no <local-commit> is given. The new history
+ includes only the commits (including merges) that
+ affected <prefix>, and each of those commits now has the
+ contents of <prefix> at the root of the project instead
+ of in a subdirectory. Thus, the newly created history
+ is suitable for export as a separate git repository.
++
+After splitting successfully, a single commit ID is printed to stdout.
+This corresponds to the HEAD of the newly created tree, which you can
+manipulate however you want.
++
+Repeated splits of exactly the same history are guaranteed to be
+identical (i.e. to produce the same commit IDs) as long as the
+settings passed to 'split' (such as '--annotate') are the same.
+Because of this, if you add new commits and then re-split, the new
+commits will be attached as commits on top of the history you
+generated last time, so 'git merge' and friends will work as expected.
++
+When a previous merge with '--squash' merged an annotated tag of the
+subtree repository, that tag needs to be available locally.
+If <repository> is given, a missing tag will automatically be fetched from that
+repository.
+
+pull <repository> <remote-ref>::
+ Exactly like 'merge', but parallels 'git pull' in that
+ it fetches the given ref from the specified remote
+ repository.
+
+push <repository> [+][<local-commit>:]<remote-ref>::
+ Does a 'split' using the <prefix> subtree of <local-commit>
+ and then does a 'git push' to push the result to the
+ <repository> and <remote-ref>. This can be used to push your
+ subtree to different branches of the remote repository. Just
+ as with 'split', if no <local-commit> is given, then HEAD is
+ used. The optional leading '+' is ignored.
+
+OPTIONS FOR ALL COMMANDS
+------------------------
+-q::
+--quiet::
+ Suppress unnecessary output messages on stderr.
+
+-d::
+--debug::
+ Produce even more unnecessary output messages on stderr.
+
+-P <prefix>::
+--prefix=<prefix>::
+ Specify the path in the repository to the subtree you
+ want to manipulate. This option is mandatory
+ for all commands.
+
+OPTIONS FOR 'add' AND 'merge' (ALSO: 'pull', 'split --rejoin', AND 'push --rejoin')
+-----------------------------------------------------------------------------------
+These options for 'add' and 'merge' may also be given to 'pull' (which
+wraps 'merge'), 'split --rejoin' (which wraps either 'add' or 'merge'
+as appropriate), and 'push --rejoin' (which wraps 'split --rejoin').
+
+--squash::
+ Instead of merging the entire history from the subtree project, produce
+ only a single commit that contains all the differences you want to
+ merge, and then merge that new commit into your project.
++
+Using this option helps to reduce log clutter. People rarely want to see
+every change that happened between v1.0 and v1.1 of the library they're
+using, since none of the interim versions were ever included in their
+application.
++
+Using '--squash' also helps avoid problems when the same subproject is
+included multiple times in the same project, or is removed and then
+re-added. In such a case, it doesn't make sense to combine the
+histories anyway, since it's unclear which part of the history belongs
+to which subtree.
++
+Furthermore, with '--squash', you can switch back and forth between
+different versions of a subtree, rather than strictly forward. 'git
+subtree merge --squash' always adjusts the subtree to match the exactly
+specified commit, even if getting to that commit would require undoing
+some changes that were added earlier.
++
+Whether or not you use '--squash', changes made in your local repository
+remain intact and can be later split and send upstream to the
+subproject.
+
+-m <message>::
+--message=<message>::
+ Specify <message> as the commit message for the merge commit.
+
+OPTIONS FOR 'split' (ALSO: 'push')
+----------------------------------
+These options for 'split' may also be given to 'push' (which wraps
+'split').
+
+--annotate=<annotation>::
+ When generating synthetic history, add <annotation> as a prefix to each
+ commit message. Since we're creating new commits with the same commit
+ message, but possibly different content, from the original commits, this
+ can help to differentiate them and avoid confusion.
++
+Whenever you split, you need to use the same <annotation>, or else you
+don't have a guarantee that the new re-created history will be identical
+to the old one. That will prevent merging from working correctly. git
+subtree tries to make it work anyway, particularly if you use '--rejoin',
+but it may not always be effective.
+
+-b <branch>::
+--branch=<branch>::
+ After generating the synthetic history, create a new branch called
+ <branch> that contains the new history. This is suitable for immediate
+ pushing upstream. <branch> must not already exist.
+
+--ignore-joins::
+ If you use '--rejoin', git subtree attempts to optimize its history
+ reconstruction to generate only the new commits since the last
+ '--rejoin'. '--ignore-joins' disables this behavior, forcing it to
+ regenerate the entire history. In a large project, this can take a long
+ time.
+
+--onto=<onto>::
+ If your subtree was originally imported using something other than git
+ subtree, its history may not match what git subtree is expecting. In
+ that case, you can specify the commit ID <onto> that corresponds to the
+ first revision of the subproject's history that was imported into your
+ project, and git subtree will attempt to build its history from there.
++
+If you used 'git subtree add', you should never need this option.
+
+--rejoin::
+ After splitting, merge the newly created synthetic history back into
+ your main project. That way, future splits can search only the part of
+ history that has been added since the most recent '--rejoin'.
++
+If your split commits end up merged into the upstream subproject, and
+then you want to get the latest upstream version, this will allow git's
+merge algorithm to more intelligently avoid conflicts (since it knows
+these synthetic commits are already part of the upstream repository).
++
+Unfortunately, using this option results in 'git log' showing an extra
+copy of every new commit that was created (the original, and the
+synthetic one).
++
+If you do all your merges with '--squash', make sure you also use
+'--squash' when you 'split --rejoin'.
+
+
+EXAMPLE 1. 'add' command
+------------------------
+Let's assume that you have a local repository that you would like
+to add an external vendor library to. In this case we will add the
+git-subtree repository as a subdirectory of your already existing
+git-extensions repository in ~/git-extensions/:
+
+ $ git subtree add --prefix=git-subtree --squash \
+ git://github.com/apenwarr/git-subtree.git master
+
+'master' needs to be a valid remote ref and can be a different branch
+name
+
+You can omit the '--squash' flag, but doing so will increase the number
+of commits that are included in your local repository.
+
+We now have a ~/git-extensions/git-subtree directory containing code
+from the master branch of git://github.com/apenwarr/git-subtree.git
+in our git-extensions repository.
+
+EXAMPLE 2. Extract a subtree using 'commit', 'merge' and 'pull'
+---------------------------------------------------------------
+Let's use the repository for the git source code as an example.
+First, get your own copy of the git.git repository:
+
+ $ git clone git://git.kernel.org/pub/scm/git/git.git test-git
+ $ cd test-git
+
+gitweb (commit 1130ef3) was merged into git as of commit
+0a8f4f0, after which it was no longer maintained separately.
+But imagine it had been maintained separately, and we wanted to
+extract git's changes to gitweb since that time, to share with
+the upstream. You could do this:
+
+ $ git subtree split --prefix=gitweb --annotate='(split) ' \
+ 0a8f4f0^.. --onto=1130ef3 --rejoin \
+ --branch gitweb-latest
+ $ gitk gitweb-latest
+ $ git push git@github.com:whatever/gitweb.git gitweb-latest:master
+
+(We use '0a8f4f0^..' because that means "all the changes from
+0a8f4f0 to the current version, including 0a8f4f0 itself.")
+
+If gitweb had originally been merged using 'git subtree add' (or
+a previous split had already been done with '--rejoin' specified)
+then you can do all your splits without having to remember any
+weird commit IDs:
+
+ $ git subtree split --prefix=gitweb --annotate='(split) ' --rejoin \
+ --branch gitweb-latest2
+
+And you can merge changes back in from the upstream project just
+as easily:
+
+ $ git subtree pull --prefix=gitweb \
+ git@github.com:whatever/gitweb.git master
+
+Or, using '--squash', you can actually rewind to an earlier
+version of gitweb:
+
+ $ git subtree merge --prefix=gitweb --squash gitweb-latest~10
+
+Then make some changes:
+
+ $ date >gitweb/myfile
+ $ git add gitweb/myfile
+ $ git commit -m 'created myfile'
+
+And fast forward again:
+
+ $ git subtree merge --prefix=gitweb --squash gitweb-latest
+
+And notice that your change is still intact:
+
+ $ ls -l gitweb/myfile
+
+And you can split it out and look at your changes versus
+the standard gitweb:
+
+ git log gitweb-latest..$(git subtree split --prefix=gitweb)
+
+EXAMPLE 3. Extract a subtree using a branch
+-------------------------------------------
+Suppose you have a source directory with many files and
+subdirectories, and you want to extract the lib directory to its own
+git project. Here's a short way to do it:
+
+First, make the new repository wherever you want:
+
+ $ <go to the new location>
+ $ git init --bare
+
+Back in your original directory:
+

+appp.sh is a script that is supposed to be used together with ExternalEditor
+for Mozilla Thunderbird. It will let you include patches inline in e-mails
+in an easy way.
+
+Usage:
+- Generate the patch with git format-patch.
+- Start writing a new e-mail in Thunderbird.
+- Press the external editor button (or Ctrl-E) to run appp.sh
+- Select the previously generated patch file.
+- Finish editing the e-mail.
+
+Any text that is entered into the message editor before appp.sh is called
+will be moved to the section between the --- and the diffstat.
+
+All S-O-B:s and Cc:s in the patch will be added to the CC list.
+
+To set it up, just install External Editor and tell it to use appp.sh as the
+editor.
+
+Zenity is a required dependency.

+TL;DR: Run update_unicode.sh after the publication of a new Unicode
+standard and commit the resulting unicode-widths.h file.
+
+The long version
+================
+
+The Git source code ships the file unicode-widths.h which contains
+tables of zero and double width Unicode code points, respectively.
+These tables are generated using update_unicode.sh in this directory.
+update_unicode.sh itself uses a third-party tool, uniset, to query two
+Unicode data files for the interesting code points.
+
+On first run, update_unicode.sh clones uniset from Github and builds it.
+This requires a current-ish version of autoconf (2.69 works per December
+2016).
+
+On each run, update_unicode.sh checks whether more recent Unicode data
+files are available from the Unicode consortium, and rebuilds the header
+unicode-widths.h with the new data. The new header can then be
+committed.

+code editor which runs on your desktop and is available for
+[Windows](https://code.visualstudio.com/docs/setup/windows),
+[macOS](https://code.visualstudio.com/docs/setup/mac) and
+[Linux](https://code.visualstudio.com/docs/setup/linux). Among other languages,
+it has [support for C/C++ via an extension](https://github.com/Microsoft/vscode-cpptools) with
+[debugging support](https://code.visualstudio.com/docs/editor/debugging)
+
+To get help about "how to personalize your settings" read:
+[How to set up your settings](https://code.visualstudio.com/docs/getstarted/settings)
+
+To start developing Git with VS Code, simply run the Unix shell script called
+`init.sh` in this directory, which creates the configuration files in
+`.vscode/` that VS Code consumes. `init.sh` needs access to `make` and `gcc`,
+so run the script in a Git SDK shell if you are using Windows.
