You can run "svnversion ." against your checked-out copy to get a revision
number for your subtree. It doesn't increase with activity outside that
subtree.

I would typically have a $Id$ in each individual file, plus have "make dist"
(or whatever else you use to build a package) do "svnversion ." to generate
a release number for your bundle of files.

If the output of svnversion doesn't match /^\d+$/, then your working copy
doesn't actually correspond to any particular revision in the repository,
which can be used as a handy sanity check against building packages that
cannot be reconstructed from the repository alone.
