I just realized there is such a document: http://www.python.org/dev/peps/pep-0394/ According to it: python2 will refer to some version of Python 2.x python3 will refer to some version of Python 3.x python should refer to the same target as python2 but may refer to python3 on some bleeding edge distributions And it has full details about all the symlinks etc. So it's not just linuces. I'd read it before preparing the patch. -- Regards, Ruslan Tinderboxing kills... the drives.
