Today pypy and CPython's "setup.py bdist" generate the same filename but incompatible bdists. This makes it difficult to share both bdists in the same folder or index. Instead, they should generate different bdist filenames because one won't work with the other implementation. This PEP specifies a tagging system that includes enough information to decide whether a particular bdist is expected to work on a particular Python
Consider using sys.implementation to get name/version. The cache_tag should be particularly helpful. The 2-character approach for implementation names requires unnecessary curating. -eric
