Script to extract design rules from Pads Layout

Before I write this myself, I am looking to see if anyone has a script that will sort the ascii rules output file into something more readable.  I set up extensive rules for my designs and because of the hierarchical nature of Rules, it can sometimes be difficult to keep track of everything, particularly because many of our control board are heavy into motor control and I find I change widths in the rules for various nets on the fly.  It would also be handy to review the rules of a design that is coming up for eco changes prior to starting. After exporting the rules set  the ascii file for my current design has 4451 lines.  (Just a blank startup has 960 lines) What I would like is the default rules table, assigned routing layers and vias for reference and then just a list of nets, classes and what value deviates from the default.  For example, if the only difference between my standard power nets and my 24V net is the spacing, that is all I want to see under the 24V listing.
