Another stat that I just computed, Eggs have had.. what 15 years? or so as a format and in that time they have accumulated 41,060 eggs uploaded to PyPI. In the uh, 2 or 3 years that Wheels have been around they have accumulated 38,720 total files on PyPI. We’re close to having Wheels beat Eggs in both the download counts and the number of files available. > >> Variants of this generator are in use in both Mandriva and Mageia, > > Ah, that's likely to have an impact.

Right now both distutils and setuptools will generate an egg-info metadata when installing projects (though distutils generates a file and setuptools a directory). However wheels install a dist-info directory. I don’t have a better suggestion for name other than I’d prefer not to bake more things onto the “egg” terminology since we (Python packaging upstream) are trying to phase it out. ----------------- Donald Stufft PGP: 0x6E3CBCE93372DCFA // 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
