I don't think that's ideal either.  I'd rather use the authors' version
and then allow an override by the repository maintainer.  Otherwise
you'll certainly end up with different version levels between repos and
that's not a good scenario for the user.

The repo could associate a content hash with the version to generate a
unique identifier (and some insurance against corruption) for a
particular library snapshot.  I wonder if Emacs has a standard way to do
this (ignoring comments and whitespace).
