# This eclass provides generic functions to make the writing of horde
# ebuilds fairly trivial since there are many horde applications and
# they all share the same basic install process.

# EHORDE_SNAP
# This variable tracks whether the user is using a snapshot version
#
# EHORDE_SNAP_BRANCH
# You set this via the ebuild to whatever branch you wish to grab a
# snapshot of.  Typically this is 'HEAD' or 'RELENG'.
#
# EHORDE_CVS
# This variable tracks whether the user is using a cvs version
