5# mercurial: Fetch sources from mercurial repositories, similar to cvs.eclass. 5# @ECLASS: mercurial.eclass
6# To use this from an ebuild, set EHG_REPO_URI in your ebuild. Then either 6# @MAINTAINER:
7# leave the default src_unpack or call mercurial_src_unpack. 7# Krzysztof Pawlik <nelchael@gentoo.org>
8# Dirkjan Ochtman <djc@gentoo.org>
9# @BLURB: This eclass provides generic mercurial fetching functions
10# @DESCRIPTION:
11# This eclass provides generic mercurial fetching functions. To fetch sources
12# from mercurial repository just set EHG_REPO_URI to correct repository URI. If
13# you need to share single repository between several ebuilds set EHG_PROJECT to
14# project name in all of them.
