I presume that's referring to this: http://www.handle.net/python_licenses/python1.6_9-5-00.html http://www.python.org/download/releases/1.6/license_faq/ This is looking like a hairy mess. I would recommend seeking an alternative to this code that's under a simpler license. One unfortunate consequence of license proliferation is that it's harder for code to be reused. For your own code, please use one of the better-known licenses - MIT, GPL, etc - as it will make life ever so much easier for the next person! Alternatively, since this is something that's still in current Python releases (at least, that's how I understand your opening paragraphs), this could be something to take up with the Python dev/legal team. You may be able to use it under the terms of the modern Python license: http://docs.python.org/3.3/license.html But before you publish, I'd look for an authoritative answer from someone in the PSF (which may involve a source-file edit to update the license annotation).
