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