#! /usr/bin/env python
"""
Usage:  checkmodule.py [-b backend] <module-name>

Compiles the PyPy extension module from pypy/module/<module-name>/
into a fake program which does nothing. Useful for testing whether a
modules compiles without doing a full translation. Default backend is cli.

WARNING: this is still incomplete: there are chances that the
compilation fails with strange errors not due to the module. If a
module is known to compile during a translation but don't pass
checkmodule.py, please report the bug (or, better, correct it :-).
