9##
10## These are internal variables used by this, and other apache-related eclasses,
11## and thus should not need to be used by the ebuilds themselves (the ebuilds
12## should know what version of Apache they are building against).

17##
18## Stores the version of apache we are going to be ebuilding. This variable is
19## set by the need_apache{|1|2} functions.
20##
21## This needs to stay as '1' until apache2 is on by default -- although it
22## doesn't matter much as it's set by the need_apache functions.
