ParseTree version 3.0.4 has been released!

* <http://rubyforge.org/projects/parsetree/>
* <http://www.zenspider.com/ZSS/Products/ParseTree/>
* <ryand-ruby / zenspider.com>

ParseTree is a C extension (using RubyInline) that extracts the parse
tree for an entire class or a specific method and returns it as a
s-expression (aka sexp) using ruby's arrays, strings, symbols, and
integers.

As an example:

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

becomes:

  [:defn,
    :conditional1,
    [:scope,
     [:block,
      [:args, :arg1],
      [:if,
       [:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],
       [:return, [:lit, 1]],
       nil],
      [:return, [:lit, 0]]]]]
