10 # cvs eclass.
11 #
12 # This eclass provides the generic darcs fetching functions.
13 # to use from an ebuild, set the 'ebuild-configurable settings' below in your
14 # ebuild before inheriting. then either leave the default src_unpack or extend
15 # over darcs_src_unpack.
16
17 # Most of the time, you will define only $EDARCS_REPOSITORY in your
18 # ebuild.
