What is cx_Freeze? cx_Freeze is a set of scripts and modules for freezing Python scripts into executables, in much the same way that py2exe and py2app do. Unlike these two tools, cx_Freeze is cross platform and should work on any platform that Python itself works on. It supports Python 2.3 or higher, including Python 3. Where do I get it? http://cx-freeze.sourceforge.net What's new?

Thanks to Almar Klein for the initial p atch. 3) Clarified the documentation on the --replace-paths option. Thanks to Thomas Kluyver for the patch.
