Fork of nathansobo/treetop
Description: A Ruby-based parsing DSL based on parsing expression grammars.
Homepage: http://treetop.rubyforge.org
Clone URL: git://github.com/juretta/treetop.git
Search Repo: 
Broke dependency on facets and trying to coexist with Rails.

Facets methods #camelize and #tabto have been duplicated in String 
extension. #camelize has been rename to #treetop_camelize so I don't step 
on Rails's version but also don't have to be at its mercy. The #blank? 
method is only added on String if it hasn't already been defined. Don't 
define my own version because this one seems pretty hard to get wrong in 
the manner Treetop uses it.
