I have added type checking to bdist_rpm, eliminated the ability to
override meta-data supplied in './setup.py', and changed the function
names to the standard Distutils style. Tomorrow I hope to be building with
`rpm -ba` instead of `rpm -ta` and I have some options I will add. The
patch to existing files and the 'package_data' file have not changed.
