PEP 314 - requirements for Python itself
PEP 314 introduces metadata that explains what packages are required by a particular package. Is there any way to express what version of Python itself is required? Cheers, -- Mark Nottingham http://www.mnot.net/ -- http://mail.python.org/mailman/listinfo/python-list
Re: PEP 314 - requirements for Python itself
Yep, I'm doing that (thanks!). I was looking for some normal (hopefully, machine-readable) way to indicate it so that people can figure out the version of Python required before they download the package.

Fwd: PEP 314 - requirements for Python itself
I was thinking more about things where people can search for packages that need different versions of python, etc.; not so much for automation.
