7 # This eclass handles depending on apache in a sane way and providing
8 # information about where certain interfaces are located.
9
10 # NOTE: If you use this, be sure you use the need_* call after you have
11 # defined DEPEND and RDEPEND. Also note that you can not rely on the
12 # automatic RDEPEND=DEPEND that portage does if you use this eclass.
13 # See bug 107127 for more information.

15 ######
16 ## Apache Common Variables
17 ##
18 ## These are internal variables used by this, and other apache-related eclasses,
19 ## and thus should not need to be used by the ebuilds themselves (the ebuilds
20 ## should know what version of Apache they are building against).
21 ######
22
23 ####
24 ## APACHE_VERSION
25 ##
26 ## Stores the version of apache we are going to be ebuilding. This variable is
27 ## set by the need_apache{|1|2} functions.
