bourne shell parser in python

[Dan Stromberg]

Hi folks.

We have a huge collection of sysadmin knowledge that's encoded in a vast
array of bourne shell scripts.

I'm now beginning to think that a transition to cfengine or similar might
be a good idea, but I'm loathe to toss out all that /bin/sh code that's
kept us from having to worry about neglecting this, that and the other
thing for so long.

So I guess my question is: "Is there a /bin/sh parser written in one of
the many python-based parser-generator systems?"

Thanks!
