RE: Version numbers in the sources

One of the most useful reasons for $Id$ and its variants is to try and
really keep track of what is in production versus development, via
'strings', 'what' etc. We generally provide a --modules arg to our
production products, which dumps all the $Id$ strings that the binary in
question was built with. This gives us some assurance that the code we think
it was built with is the version in production. The use of symbolic tags
really helps here too.

So if a similiar feature was in svnlook or other tool, an 'svnlook
--versions' or such would dump all the version strings embedded as per
Peter's request.

Of course it all falls down when someone checks out a version, changes it,
builds it, deploys it and THEN checks in. But that is what the big stick is
there for - re-education!

I understand that you are asking for something a bit more general -
but for what it's worth:

The debian package has a version, be it 0.15 or 0.16. You can see from
the CHANGES file that which revision is this - for 0.15 it's 3687, for
0.16 it's 3987.

So, then you know what revision your commit-access-control.pl is (the
one you started out with). And then it's a trivial job of doing:

  svn diff -r 3987:HEAD
http://svn.collab.net/repos/trunk/tools/hook-scripts/commit-access-control.p
l

to find out the differences. Same for log messages ofcourse.
