And while we're enumerating other tools that can do this, one of them is
Manuel (https://pypi.python.org/pypi/manuel)

Example tests:
https://github.com/zopefoundation/zdaemon/blob/6d84614/src/zdaemon/README.txt#L45

with the interpretation of 'sh>' defined in
https://github.com/zopefoundation/zdaemon/blob/6d84614/src/zdaemon/tests/tests.py#L422

Okay, now that I look at that

  transform=lambda s: 'system("%s")\n' % s.rstrip()

I'm a little bit scared.

<Axioplase> phrakture: not enought yet... read it rot13'd, and you'll be
            hardcore ^^
<phrakture> I read it as analog output on an oscilliscope
<mgedmin> rot13, bah, try reading the gzipped source tarball
