 # @ECLASS: apache-module.eclass
 # @MAINTAINER:
 # apache-devs@gentoo.org
 # @BLURB: Provides a common set of functions for apache modules
 # @DESCRIPTION:
 # This eclass handles apache modules in a sane way.
 #
 # To make use of this eclass simply call one of the need/want_apache functions
 # described in depend.apache.eclass. Make sure you use the need/want_apache call
 # after you have defined DEPEND and RDEPEND. Also note that you can not rely on
 # the automatic RDEPEND=DEPEND that portage does if you use this eclass.
 #
 # See Bug 107127 for more information.
 #
 # @EXAMPLE:
 #
 # Here is a simple example of an ebuild for mod_foo:
 #
 # @CODE
 # APACHE2_MOD_CONF="42_mod_foo"
 # APACHE2_MOD_DEFINE="FOO"
 # need_apache2
 # @CODE
 #
 # A more complicated example for a module with non-standard locations:
 #
 # @CODE
 # APXS2_S="${S}/apache22/src"
 # APACHE2_MOD_FILE="${APXS2_S}/${PN}.so"
 # APACHE2_MOD_CONF="42_${PN}"
 # APACHE2_MOD_DEFINE="FOO"
 # DOCFILES="docs/*.html"
 # need_apache2_2
 # @CODE
 #
 # A basic module configuration which just loads the module into apache:
 #
 # @CODE
 # <IfDefine FOO>
 # LoadModule foo_module modules/mod_foo.so
 # </IfDefine>
 # @CODE

 # PUBLIC VARIABLES
 # ==============================================================================

 # @VARIABLE: APXS2_S
 # @DESCRIPTION:
 # Path to temporary build directory. (Defaults to `${S}/src' if it exists,
 # `${S}' otherwise)

 # @VARIABLE: APXS2_ARGS
 # @DESCRIPTION:
 # Arguments to pass to the apxs tool. (Defaults to `-c ${PN}.c')

 # @VARIABLE: APACHE2_EXECFILES
 # @DESCRIPTION:
 # List of files that will be installed into ${APACHE_MODULE_DIR} beside
 # ${APACHE2_MOD_FILE}. In addition, this function also sets the executable
 # permission on those files.

 # @VARIABLE: APACHE2_MOD_CONF
 # @DESCRIPTION:
 # Module configuration file installed by src_install (minus the .conf suffix and
 # relative to ${FILESDIR}).

 # @VARIABLE: APACHE2_MOD_DEFINE
 # @DESCRIPTION:
 # Name of define (e.g. FOO) to use in conditional loading of the installed
 # module/its config file, multiple defines should be space separated.

 # @VARIABLE: APACHE2_MOD_FILE
 # @DESCRIPTION:
 # Name of the module that src_install installs minus the .so suffix. (Defaults
 # to `${APXS2_S}/.libs/${PN}.so')

 # @VARIABLE: APACHE2_VHOST_CONF
 # @DESCRIPTION:
 # Virtual host configuration file installed by src_install (minus the .conf
 # suffix and relative to ${FILESDIR}).

 # @VARIABLE: DOCFILES
 # @DESCRIPTION:
 # If the exported src_install() is being used, and ${DOCFILES} is non-zero, some
 # sed-fu is applied to split out html documentation (if any) from normal
 # documentation, and dodoc'd or dohtml'd.
