Manual:Chris G's botclasses/FixFileDescriptionPagesBot.php

This bot uses Chris G's botclasses to fix file description pages whose contents were buried in the history when a description page import was done after the image import. It generates edits that look like this. To generate the text file that you'll need, you might want to use AllPagesBot.php.
