for my own use, i use m4, python and perl, and peval()
m4 is a macro processor that you probably should not bother learning since you can do everything that it does by using Python and regular expressions, or one of the Python parsing modules. For instance PLY supports conditional lexing and start conditions which you need to change parsing rules depending on which config section you are in. There is also a package called ciscoconfparse which I don't know much about http://ciscoconfparse.wiki.sourceforge.net/ peval() is part of the IRRToolSet which can be found here: http://www.isc.org/index.pl?/sw/IRRToolSet/ --Michael Dillon
