* PEP 426 doesn't include any mention of the egg distribution format, even though it's the most popular distribution format at the moment. It should at least include the location of the metadata file in eggs (EGG-INFO/PKG-INFO) and egg installations (/EGG-INFO/PKG-INFO). "Other tools involved in Python distribution may also use this format." The egg format has never been, and never will be, officially endorsed by python-dev. The wheel format is the standard format for binary distribution, and PEP 376 defines the standard location for metadata on installed distributions.

Oh, come on, Nick, that's just silly. setuptools was included in stdlib for a short while, so the above is simply wrong. Eggs are the most widely used binary distribution format for Python package on PyPI:

wc *files.csv

25585 25598 1431013 2013-02-19-egg-files.csv 4619 4640 236694 2013-02-19-exe-files.csv 254 255 13402 2013-02-19-msi-files.csv 104691 104853 5251962 2013-02-19-tar-gz-files.csv 24 24 1221 2013-02-19-whl-files.csv 17937 18022 905913 2013-02-19-zip-files.csv 153110 153392 7840205 total

(based on todays PyPI stats)

It doesn't really help ignoring realities... and I'm saying that as one of the core devs who got setuptools kicked out of the stdlib again.
