# @BLURB: Eclass to install horde project packages
# @DESCRIPTION:
# Help manage the horde project http://www.horde.org/
#
# Based on the horde eclass:
# Author: Mike Frysinger <vapier@gentoo.org>
# CVS additions by Chris Aniszczyk <zx@mea-culpa.net>
# SNAP additions by Jonathan Polansky <jpolansky@lsit.ucsb.edu>
#
# 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.

# @ECLASS-VARIABLE: EHORDE_SNAP
# @DESCRIPTION:
# Track whether this a snapshot version or not

# @ECLASS-VARIABLE: EHORDE_SNAP_BRANCH
# @DESCRIPTION:
# You set this via the ebuild to whatever branch you wish to grab a
# snapshot of.  Typically this is 'HEAD' or 'RELENG'.

# @ECLASS-VARIABLE: EHORDE_SNAP_PV
# @DESCRIPTION:
# The date of the snapshot to fetch

# @ECLASS-VARIABLE: EHORDE_VCS
# @DESCRIPTION:
# Track whether this is a live version or not

# This eclass requires at least EAPI-3
