# @BLURB: This eclass provides generic mercurial fetching functions |

# @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. |
