This script is regularly tested with CPython 2.7 and 3.5, and
occasionally tested with CPython 2.6 and PyPy 4.
Support for CPython 2.6 will be dropped eventually, but is kept up for as
long as reasonably convenient.
CPython 2.5 and earlier are not supported.
On Jython target detection does not work (use --os and --cpu).
