tp versions

[Karl Berry]

Many of the .pm files evidently define their own version.
Is there a reason why they all need a separate version?
It seems like a nightmare to me.
If the idea is to have unique version information for the submodules,
then I think we should use something automated, like $Id$ or $Revision$.

Meanwhile, where is the "real" version number defined?  It would be best
to be able to use the value in configure.ac (currently 4.13.90), but if
that's not practical, we can just edit it.  But let's edit it in only
one place :).

On a semi-related front: does the ./Changes file serve a real purpose?
I don't see it.

Thanks,
karl
