I want to get the last XXX removed from PEP 241 so it can be posted to c.l.py.a and python-dev *today*. The missing bit is: Platform (multiple use) A (XXX whitespace? comma?)-separated list of platform specifications. Platform specifications are limited to the following list: XXX copy list from PPD? SourceForge? Example: 'XXX' So, what to do? Some options are: * Specify a short and incomplete list of platform specs: MacOS/Windows/POSIX/BeOS/... State in the PEP that this list is incomplete. Binary distributions will use a different metadata header (Compiled-Platform, Supported-Platform, or something like that) to specify the OS and CPU they were compiled for. * Leave 'Platform' to be filled in for binary distributions. Developers should put platform limitation notes in the 'Description'. I lean toward #1, and if I don't hear any strong reasons to do otherwise, that's what I'll check it and post, sometime after 5PM EST. --amk
