12 # @BLURB: This eclass provides generic mercurial fetching functions
13 # @DESCRIPTION:
14 # This eclass provides generic mercurial fetching functions. To fetch sources
15 # from mercurial repository just set EHG_REPO_URI to correct repository URI. If
16 # you need to share single repository between several ebuilds set EHG_PROJECT to
17 # project name in all of them.
