Setup file for the distuils module.
It includes the following features:
- creation and installation of configuration files with installation data
- automatic detection and usage of GNU99 standard for C compiler
- automatic MANIFEST.in check
- automatic generation of .mo locale files
- automatic permission setting on POSIX systems for installed files
Because of all the features, this script is nasty and big.
