Syntax would be the same as for lexer. Only problem is that some additional
checks might be necessary. Basically disabling the lexer only check for
paraphrase would work on tokens only (I think). It's a 3-5 line change in
RuleBlock.java.

Try it out and if it's as I think it might be a simple patch. Then feeding
it to me wouldn't be a big problem.

Basically changes to the codebase are done by ppl submitting patches to the
maintainers (Terence, me and a few others with repository write access)

No problem ;)

 Why don't we just invite them to dinner and massacre them all when they're
  drunk? You heard the man. There's seven hundred thousand of them. Ah? ..
           So it'd have to be something simple with pasta, then.
