8# @BLURB: Functions to allow ebuilds to depend on apache
9# @DESCRIPTION:
10# This eclass handles depending on apache in a sane way and provides information
11# about where certain binaries and configuration files are located.
12#
13# To make use of this eclass simply call one of the need/want_apache functions
14# described below. Make sure you use the need/want_apache call after you have
15# defined DEPEND and RDEPEND. Also note that you can not rely on the automatic
16# RDEPEND=DEPEND that portage does if you use this eclass.
17#
18# See Bug 107127 for more information.
19#
20# @EXAMPLE:
21#
22# Here is an example of an ebuild depending on apache:
23#
24# @CODE
25# DEPEND="virtual/Perl-CGI"
26# RDEPEND="${DEPEND}"
27# need_apache2
28# @CODE
29#
30# Another example which demonstrates non-standard IUSE options for optional
31# apache support:
32#
33# @CODE
34# DEPEND="server? ( virtual/Perl-CGI )"
35# RDEPEND="${DEPEND}"
36# want_apache2 server
37#
38# pkg_setup() {
39# depend.apache_pkg_setup server
40# }
