Python Software Foundation License
From Wikipedia, the free encyclopedia
The Python Software Foundation License is a BSD-style, open source license which is compatible with the GNU General Public License (GPL). Its primary use is for distribution of the Python project software. Unlike the GPL the Python license lets you distribute a modified version without making your changes open source.
Early versions of this license were not compatible with the GPL. The reason given by Free Software Foundation was that "this Python license is governed by the laws of the 'State of Virginia', in the USA, and the GPL does not permit this."
The year that Python's creator Guido van Rossum changed the license to fix this incompatibility he was awarded the Free Software Foundation Award for the Advancement of Free Software. This may have been in recognition of his agreement to change the Python license.
