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.
