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.

18     # ebuild.
