homepage

I don’t believe aliases would help, on the contrary. There already are a good number of fields to remember. Anyway I expect people to use "pysetup create" or copy-pasting, so the spelling is not important: nobody will really have to remember it. I have no personal opinion on "home page" vs. "homepage", so I just accept what the PEP decided.
Postponing to 3.4 has no value. The reasons for rejecting this will still apply. Please keep this closed.
See PEP 1 for the PEP process. See the month-long discussions on distutils-sig and python-dev two years ago on the packaging PEPs to see how long it can be.
