I had a quick look around and found this:

   filepp

   http://www.cabaret.demon.co.uk/filepp/

>From the web page:

   filepp is designed to be a highly customisable generic file pre-processor. 
   Its C pre-processor style functionality should just be considered its 
default 
   behaviour, as it can be used as a frontend for almost any file 
pre-processing 
   or conversion processes. filepp can be customised to do other sorts of 
   pre-processing or file conversion by using filepp modules, which are written 
   in Perl. Therefore, anyone who knows how to program in Perl should find 
   customising filepp very easy.  

Mind you I haven't tried it, and I'm not sure if it implements exactly what we
want.

However, perhaps it can be bent into shape.

It is under the GPL so distributing it should not be a problem, and it is
Perl so portability should be okay.

Cheers,
Bernie.
