| # @BLURB: This eclass provides functions for fetch and unpack darcs repositories |
| # @DESCRIPTION: |
| # This eclass provides the generic darcs fetching functions. |
| # |
| # Define the EDARCS_REPOSITORY variable at least. |
| # The ${S} variable is set to ${WORKDIR}/${P}. |
| |

| # support for tags |
| |
| inherit eutils # eshopts_{push,pop} |
| |
| # Don't download anything other than the darcs repository |
| SRC_URI="" |
| |
| # You shouldn't change these settings yourself! The ebuild/eclass inheriting |
| # this eclass will take care of that. |
