The purpose of defining the 'Requires-Dist' field in PEP 345 is to allow for a standardized way of spelling dependences. If we don't standardize on the versioning, then we won't have gained any ground: we might as well punt and keep using setuptools, and *forbid* putting versions into 'Requires-Dist' at all. > So we can move on and propose the PEP 345 change unindependantly from > a version comparison tool. I don't understand why we can't just settle on the reduced set: the exotic cases aren't supported today (in distutils), and are mappable onto the verlib case with some effort.
