7 # This eclass provides the generic cvs fetching functions.
8 # to use from an ebuild, set the 'ebuild-configurable settings' below in your ebuild before inheriting.
9 # then either leave the default src_unpack or extend over cvs_src_unpack.
10 # if you find that you need to call the cvs_* functions directly, i'd be interested to hear about it.
