Eh? I implemented PEP 426 (draft-at-the-time) markers in the feature I mentioned above. Hm. Actually, looking over it now, I see the real reason it's experimental: it was implemented based on consensus-in-progress for PEP 426, so not a finalized PEP. It also sort-of handles PEP 345. And the Jython fallback, IIRC, was maybe only doing PEP 345. (And setuptools itself only needed the Python version and platform name.) So it's actually a bit of a mess -- which is why it wasn't documented, in order to avoid people forcing the new PEP's hand with another de facto standard. I just figured it would get us most of the way there and when the PEP dust settled, the tests and code could be tweaked a bit to match, then documented with reference to the PEP. _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
