From 4710c53dcad1ebf3755f3efb9e80ac24bd72a9b2 Mon Sep 17 00:00:00 2001 From: darylm503 Date: Mon, 16 Apr 2012 22:12:42 +0000 Subject: AppPkg/Applications/Python: Add Python 2.7.2 sources since the release of Python 2.7.3 made them unavailable from the python.org web site. These files are a subset of the python-2.7.2.tgz distribution from python.org. Changed files from PyMod-2.7.2 have been copied into the corresponding directories of this tree, replacing the original files in the distribution.
