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.
