# @ECLASS: apache-module.eclass
# @MAINTAINER:
# apache-bugs@gentoo.org
# @SUPPORTED_EAPIS: 5 6 7
# @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.
