# This eclass provides the generic darcs fetching functions.
# to use from an ebuild, set the 'ebuild-configurable settings' below in your
# ebuild before inheriting.  then either leave the default src_unpack or extend
# over darcs_src_unpack.

# Most of the time, you will define only $EDARCS_REPOSITORY in your
# ebuild.

# TODO: support for tags, ...

# Don't download anything other than the darcs repository
