In Python cheese shop, there is a field that shows the Python version that is required by a listed package.
I have not found this covered in the distutils documentation: How do you add the Python version information into the setup script of a package? Unfortunately, the keyword list: http://docs.python.org/dist/meta-data.html is incomplete (for example, the "provides" and "requires" keywords are not listed, even though covered in the previous chapters of the documentation). -Samuel -- http://mail.python.org/mailman/listinfo/python-list
