Certain changes are easy to fix with code converters like 2to3. For example, changing print statements into functions is trivial. I don't bother trying to handle those. There is still a lot of things that could be added. However, when porting a large code base to Python 3, I found it useful.I hope other people might use it and submit improvements. If someone need pre-built binaries (e.g. Windows), I would be willing to do it.
