6## Apache Common Variables 6# @MAINTAINER: apache-devs@gentoo.org
7## 7# @BLURB: Functions to allow ebuilds to depend on apache
8## These are internal variables used by this, and other apache-related eclasses, 8# @DESCRIPTION:
9## and thus should not need to be used by the ebuilds themselves (the ebuilds 9# This eclass handles depending on apache in a sane way and providing
10## should know what version of Apache they are building against). 10# information about where certain interfaces are located.
11###### 11#
12# @NOTE: If you use this, be sure you use the need_* call after you have defined
13# DEPEND and RDEPEND. Also note that you can not rely on the automatic
14# RDEPEND=DEPEND that portage does if you use this eclass.
15#
16# See bug 107127 for more information.
