Revision: 7849 Author: russblau Date: 2009-12-31 17:56:33 +0000 (Thu, 31 Dec 2009)
Log Message: ----------- Port redirect.py to rewrite branch; to do this, some options had to be removed and some command-line arguments changed. Because this is a port rather than a newly-written script, it may contain some unused variables/methods and could benefit from refactoring.
Added Paths: ----------- branches/rewrite/scripts/redirect.py
