5 # @ECLASS: depend.apache.eclass
6 # @MAINTAINER: apache-devs@gentoo.org
7 # @BLURB: Functions to allow ebuilds to depend on apache
8 # @DESCRIPTION:
9 # This eclass handles depending on apache in a sane way and providing
10 # information about where certain interfaces are located.
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.
