The answer to this is not as simple as it would seem it should be, because
"/mywebdir" could be a directory such that DocumentRoot + "/mywedir" would
give you the path on disk, but it could also be an alias, in which case
there is no way to know what directory you're in...

But assuming you don't use aliases, req.filename will tell you what
directory you're in.

Also you may want to take a look at the publisher.py code, it deals with
that same issue.
