Parsing csh scripts with python

[David Hirschfield]

Is there a module out there that would be able to parse a csh script and
give me back a parse tree?

I need to be able to parse the script, modify some variable settings and
then write the script back out so that the only changes are the
variables I've modified (comments, ordering of statements, etc. must
remain the same).

I looked at shlex, but I don't think it will do what I need.
Any suggestions would be appreciated,
-Dave

What about regular expressions?

probably overkill here, but you might want to look into one of python's
templating libs. They make generating lots of "similar except for..."
code and markup relatively painless.
