Configuration program for botan
(C) 2009,2010,2011,2012,2013,2014,2015 Jack Lloyd
Botan is released under the Simplified BSD License (see license.txt)
Tested with CPython 2.6, 2.7, 3.2, 3.3 and PyPy 1.5
Python 2.5 works if you change the exception catching syntax:
perl -pi -e 's/except (.*) as (.*):/except $1, $2:/g' configure.py
Jython - Target detection does not work (use --os and --cpu)
CPython 2.4 and earlier are not supported
Has not been tested with IronPython
