-# This eclass handles depending on apache in a sane way and providing
-# information about where certain interfaces are located.
+# This eclass handles depending on apache in a sane way and provides information

-# @NOTE: If you use this, be sure you use the need_* call after you have defined

+# To make use of this eclass simply call one of the need/want_apache functions
+# described below. Make sure you use the need/want_apache call after you have

 # RDEPEND=DEPEND that portage does if you use this eclass.

+# @CODE

+#   DEPEND="server? ( virtual/Perl-CGI )"
+#   RDEPEND="${DEPEND}"
+#   want_apache2 server
