I don't know if this will address your problem (or even if it's going to
work) but I'm in the design phase of a big, but simple, perl script that
is to generate config files for an IOS router, a PIX, a NOC, some Linux
workstations and some OS X workstations on my networks. 

The idea is to have the firewall rules for, say, email generated in a
single function so all the firewalls will do what I want them to and so
the rules being generated will all be in the same place -- on the screen
when I write the code -- so I can carefully deal with the syntax
variations.

And the comments are supposed to be such that a pass over the program
with perldoc will generate my security policy -- the rules will be
readable and the same in there, and I will (hopefully) never need to
look at the actual rules on the various platforms.
