+=head1 SYNOPSIS
+
+B<dh_apache2> [S<I<debhelper options>>] [S<B<--conditional>>=I<expression>] [B<--error-handler=>I<function>] [B<-n>|B<--noscripts>]
+ [B<-e>|B<--noenable>] [B<-r>|B<--restart>]
+
+=head1 DESCRIPTION
+
+B<dh_apache2> is a debhelper program that is responsible for correctly installing
+Apache2 configuration snippets and setting postinst, prerm and dependencies in
+Apache2 web server modules and web applications.
+
+It supports the following configuration types
+
+=over 4
+
+=item *
+Apache2 modules
+
+=item *
+Apache2 configuration snippets for web applications
+
+=item *
+Apache2 sites
+
+=back
+
+B<dh_apache2> supports two modes: A limited auto-configuration heuristic or
+alternatively a configuration file driven approach. If a file named
+debian/package.apache2 exists, actual actions are determined by that file.
+
+=head1 OPERATION MODES
+
+B<dh_apache2> can be used in two modes: A configuration file driven approach and
+a heuristic approach. The configuration driven mode is fully documented in the
+B<FILES> section below. This mode is activated by supplying a L<debhelper(7)>
+configuration file (e.g. debian/I<package>.apache2).
+
+The alternative is a heuristic mode, in which no files are installed through
+B<dh_apache2>. Instead the helper will scan the package installation directory
+for recognized files and guess their purpose depending on their installation
+path in the file system. Use with caution.
+
+=head1 INVOCATION
+
+B<dh_apache2> is not part of debhelper and might require information available
+in the apache2-dev package. Packages making use of B<dh_apache2> should declare
+a build-dependency against the virtual B<dh-apache2> package.
+
+B<dh_apache2> supports both, called directly from a debian/rules file or as
+L<dh(1)> addon. In the former case the helper should run after L<dh_install(1)>
+or their respective counter parts in local implementations at earliest.
+Alternatively it can be used as L<dh> addon by invoking it with
+
+ %:
+ dh $@ --with apache2
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.apache2
+
+=item debian/apache2
+
+=back
+
+Lists files to be registered with the Apache 2 HTTP server. The file is
+interpreted as line separated list of installation stanzas, where each entry
+consists of whitespace separated values conforming to the file semantics below.
+
+=head2 FILE SEMANTICS
+
+Each line consists of a triple
+
+I<type> I<file> [I<arguments>]
+
+where the values are interpreted as follows:
+
+
+=head3 I<type>
+
+Denotes the type of file to be installed. Recognized values are B<conf>
+for Apache2 global configuration snippets, B<site> for virtual host
+configurations and B<mod> for Apache2 modules.
+
+=head3 I<file>
+
+Is interpreted as existing file name within the source package. No path
+expansion is effectuated. Just like L<dh_install(1)>, B<dh_apache2> can not
+rename files.
+
+=head3 I<arguments>
+
+Is inrerpreted as optional arguments if any, currently used by B<conf>
+stanzas only
+
+=head2 GLOBAL CONFIGURATION FILES
+
+Global configuration files (determined by the B<conf> type) must have a I<.conf>
+suffix and are installed to I</etc/apache2/conf-available>. Moreover, the
+configuration is activated in the maintainer script at installation time.
+
+Such global configuration snippets are supposed to be used by web applications.
+Such stanzas accept an optional third I<arguments> which is interpreted as
+dependency line of alternative web servers the package supports. See I<EXAMPLES>
+below.
+
+B<dh_apache2> will set dependencies in B<${misc:Recommends}> accordingly when
+this type of configuration is found. Alternatives from the optional I<argument>
+is incorporated into this dependency line.
+
+=head2 SITE CONFIGURATION FILES
+
+Site configuration files (determined by the B<site> type) must have a I<.conf>
+suffix and are installed to I</etc/apache2/sites-available>. Moreover, the
+configuration is activated in the maintainer script at installation time.
+
+Such global configuration snippets are supposed to be used by web applications
+and third party packages which install virtual host configurations. This type of
+configuration sets the same dependencies as configuration files.
+
+=head2 MODULES
+
+Modules are handled specially and are determined by the B<mod> type. Modules can
+either have a I<.conf> or I<.load> suffix. In that case the file is interpreted
+as module load file or module configuration file respectively and is nstalled to
+I</etc/apache2/mods-available>. If the file is ending with a I<.so> suffix it is
+interpreted as actual module shared object and is installed to the Apache module
+directory. Moreover, if a I<.load> file is installed the configuration is
+activated in the maintainer script at installation time.
+
+A typical module configuration has two lines, one for the I<.load> file, and one
+for the I<.so> file, albeit the latter could be installed by upstream's
+makefile, too.
+
+B<dh_apache2> will set dependencies in B<${misc:Depends}> accordingly when
+this type of configuration is found.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--error-handler=>I<function>
+
+Call the named shell I<function> if running the maintainer script fails. The
+function should be provided in the F<prerm> and F<postinst> scripts, before the
+B<#DEBHELPER#> token.
+
+=item S<B<--conditional>>=I<function>
+
+Only execute maintainer scripts if the named shell I<function> evaluates to a
+true value at installation time. This is useful to web applications which want
+to install Apache configuration files depending on a user input, for example if
+they interface to the user through L<debconf(1)>.
+
+The defaults is to always execute the scripts. The named function should be
+provided in the F<prerm>, F<postrm> and F<postinst> scripts, before the
+B<#DEBHELPER#> token.
+
+=item S<B<--restart>> S<B<-r>>
+
+In maintainer scripts, do not try to reload the web server, but restart it.
+Otherwise the default action is used, which means global configuration and
+sites make the web server to be reloaded on success, modules are restarted.
+
+=item B<-e>, B<--noenable>
+
+Install maintainer scripts accordingly, but do not enable the scripts or
+configuration by default.
+
+=item B<-n>, B<--noscripts>
+
+Do not modify F<postinst>/F<postrm>/F<prerm> maintainer scripts.
+
+
+=back
+
+=head1 NOTES
+
+Note that this command is not idempotent. L<dh_prep(1)> should be called
+between invocations of this command. Otherwise, it may cause multiple
+instances of the same text to be added to maintainer scripts.
+
+=head1 EXAMPLES
+
+The examples below lists valid entries for a debian/I<package>.apache2 file. For
+example, the two lines below install a fictional I<mod_foo> Apache module along
+a Debian specific I<.load> file:
+
+ mod src/foo/mod_foo.so
+ mod debian/foo.load
+
+The example below installs a fictional web application called phpmyfoo supplied
+in a package which also supports Lighttpd and nginx:
+
+ conf debian/phpmyfoo.conf lighttpd (>= 1.4.30) | nginx-full
+
+Or, the same example again this time without support for other web servers:
+
+ conf debian/phpmyfoo.conf
+
+As a final example, install a module called I<mod_foo> along with a site
+configuration for a fictional site configuration for the site I<example.com>:
+
+ mod src/foo/mod_foo.so
+ mod debian/foo.load
+ mod debian/foo.conf
+ site debian/example_com.conf
