ruby_parser version 2.0.6 has been released!

* <http://parsetree.rubyforge.org/>

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)))))
