+# ebuild, set the ECLASS VARIABLES as specified below in your ebuild before
+# inheriting. Then either leave the default src_unpack or extend over
+# cvs_src_unpack. If you find that you need to call the cvs_* functions
+# directly, I'd be interested to hear about it.

+# Users shouldn't change these settings! The ebuild/eclass inheriting
