If you want to develop a package publicly prior to its first release (to
benefit from others' feedback, primarily), but not in an external repo,
you have 2 choices:
-- you can simply put "Version: -1" to indicate that this should not be
- released.
+- you can simply put "Version: 0" to indicate that this should not be
+ released yet.
- or you can push to an "ephemeral" branch -- subject to rebase and eventual
removal upon finishing merge -- for the duration of the incubation.
