FYI, this is not the true revision number; it's only the revision number in 
which the directory was last modified, not the latest revision number 
within the tree.
You probably want to do a bit more processing of "svn info -R", or else 
parse the .svn/entries files yourself. There's some Python code that does 
this at:
http://svn.python.org/projects/sandbox/trunk/setuptools/setuptools/command/egg_info.py
Specifically, see the 'get_svn_revision' method for an example of 
processing .svn/entries files to find out the highest committed revision 
number in a source tree.
