I have created a table at http://www.botwiki.sno.cc/wiki/Rewrite/Porting_status to keep track of progress in porting files from the existing framework to the rewrite branch. So far it is quite incomplete (the first column is complete), but I intend to keep adding to it and encourage other developers to contribute. This can serve as a useful to-do list for those working on the project.
