ECJ's rule package is very *very* general. And not well tested, so you're on your own (though I am not aware of any bugs in it).  Another way you can do rule evolution is to use ECJ's list extension to its vector package -- see the manual.

The problem with providing rules is that there are are a zillion different *kinds* of rules, so ECJ assumes you're gonna be building your own special kind of rule system.

I've also read the manual about this package, but everything is really abstract and only of little help. I appreciate every bit of help.
