cx_Freeze is a set of utilities for freezing Python scripts into executables using many of the techniques found in Thomas Heller's py2exe, Gordon McMillan's Installer and the Freeze utility that ships with Python itself.
NOTE: Binary packages must be compatible with the Python installation on your system or you will get errors in your frozen executables about missing builtin modules or missing symbols. This is not likely to be a problem on Windows (since www.python.org is the only known distributor) but on Linux it is more likely (since Python is often packaged with the Linux distribution in different ways). If you get such errors, download the source package and build the binaries yourself.
