# @BLURB: Provides important paths for the apache web server.
# @DESCRIPTION:
# Several packages need to know apache's paths: contributed modules,
# anything that runs a vhost, and of course www-servers/apache
# itself. This eclass serves as a central location where those paths
# are defined so that everyone can retrieve them from a single
# authoritative location.
#
# These days, we could let www-servers/apache define those paths, and
# then retrieve them with $(apxs -q <variable>). However, that seems a
# bit too complicated; given that, ultimately, we have to write down
# the paths at least once, it might as well be here.
#
# Unlike the depend.apache eclass that it replaces, this eclass does not
# declare any dependencies or USE flags. Consumers must depend on apache
# themselves if desired.
