ruby_parser (RP) is a ruby parser written in pure ruby (utilizing
racc--which does by default use a C extension). RP's output is
the same as ParseTree's output: s-expressions using ruby's arrays and
base types.

As an example:

  def conditional1(arg1)
    if arg1 == 0 then
      return 1
    end
    return 0
  end

becomes:

  s(:defn, :conditional1,
   s(:args, :arg1),
   s(:scope,
    s(:block,
     s(:if,
      s(:call, s(:lvar, :arg1), :==, s(:arglist, s(:lit, 0))),
      s(:return, s(:lit, 1)),
      nil),
     s(:return, s(:lit, 0)))))

Changes:

### 3.0.0.a7 / 2012-09-21

* 3 minor enhancements:

  * Reorganized ruby_parse_extract_error so it will start much faster with a bunch of glob directories
  * RubyParserStuff#process takes optional time arg and raises Timeout::Error if it goes too long. You should rescue that, ya know...
  * ruby_parse_extract_error now checks *.rake and Rakefile on dir scan.

* 3 bug fixes:

  * 1.9: Fixed ternary state tracking so {a:f{f()},b:nil} won't trip up the lexer.
  * Fixed optional values in block args (no20/no21)
  * ruby_parse_extract_error skips non-files. Some asshats put .rb on their dirs. :(
