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.
28##
29## This needs to stay as '1' until apache2 is on by default -- although it
30## doesn't matter much as it's set by the need_apache functions.
