Most people who use Subversion know that you can access the repository with your browser to get a readonly interface that you can use to take a cursory look at the files in there.
This is how the Python repository looks like via http://svn.python.org/projects/python:
It says Revision 65620 at the top and I’ve always wondered if you could access another revision in the same simple way. Turns out there is a way.
All you need to do is add !svn/bc/REVISION to the URL:
http://svn.python.org/projects/!svn/bc/5000/python shows revision 5000 of the Python Subversion repository.
