Configuration program for botan (http://botan.randombit.net/)
(C) 2009,2010,2011,2012,2013 Jack Lloyd
Distributed under the terms of the Botan license
Tested with CPython 2.6, 2.7, 3.1 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
