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
    return 1 if arg1 == 0
    return 0
  end

becomes:

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

Changes:
