# This eclass handles depending on apache in a sane way and providing
# information about where certain interfaces are located.
# NOTE: If you use this, be sure you use the need_* 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.
######
## Apache Common Variables
##
## These are internal variables used by this, and other apache-related eclasses,
## and thus should not need to be used by the ebuilds themselves (the ebuilds
## should know what version of Apache they are building against).
######
####
## APACHE_VERSION
##
## Stores the version of apache we are going to be ebuilding. This variable is
## set by the need_apache{|1|2} functions.
##
####
#APACHE_VERSION="2"
####
## APXS2
##
## Paths to the apxs tools
####
APXS2="/usr/sbin/apxs2"
####
## APACHECTL2
##
## Paths to the apachectl tools
####
APACHECTL2="/usr/sbin/apache2ctl"
####
## APACHE2_BASEDIR
##
## Paths to the server root directories
####
APACHE2_BASEDIR="/usr/$(get_libdir)/apache2"
####
## APACHE2_CONFDIR
##
## Paths to the configuration file directories
####
APACHE2_CONFDIR="/etc/apache2"
####
## APACHE2_MODULES_CONFDIR
##
## Paths where module configuration files are kept
####
APACHE2_MODULES_CONFDIR="${APACHE2_CONFDIR}/modules.d"
####
## APACHE2_VHOSTDIR
##
## Paths where virtual host configuration files are kept
####
APACHE2_VHOSTDIR="${APACHE2_CONFDIR}/vhosts.d"
####
## APACHE2_MODULESDIR
##
## Paths where we install modules
####
APACHE2_MODULESDIR="${APACHE2_BASEDIR}/modules"
####
## APACHE2_DEPEND, APACHE2_0_DEPEND, APACHE2_2_DEPEND
##
## Dependencies for Apache 2.x
####
APACHE2_DEPEND="=net-www/apache-2*"
APACHE2_0_DEPEND="=net-www/apache-2.0*"
APACHE2_2_DEPEND="=net-www/apache-2.2*"

## NEED_APACHE_DEPEND
##
## Dependency magic based on useflags to use the right DEPEND
## If you change this, please check the DEPENDS in need_apache()
