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:

### 3.1.0 / 2012-12-06

* 2 minor enhancements:

  * Added RubyParser.for_current_ruby to provide a parser that matches your runtime. (neilconway)
  * Duck-typed IDENT_CHAR_RE instead of using RUBY_VERSION

* 3 bug fixes:

  * Cleared out body comments in class/module/defn/defs
  * Flipped lexer tests to US-ASCII to avoid encoding hell
  * yyerror is now an alias for syntax_error
