As far as I know, this module is now the most complete and robust Python implementation to read MS OLE2 files, portable on several operating systems. (please tell me if you know other similar Python modules)
OleFileIO_PL can be used as an independent module or with PIL. The goal is to have it integrated into [Pillow](http://python-imaging.github.io/), the friendly fork of PIL.
