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