ParseTree version 3.0.0 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]]]]]

   * PTTC: Made self.previous more overridable.
   * PTTC: Now all tests that have "mri_verbose_flag" activate $VERBOSE
   * PTTC: Officially added clone_same phase to generate_tests
   * PTTC: Refactored test generation to make subclasses more flexible.
   * PTTC: Refactored to use new add_tests. Much much cleaner.
   * PTTC: Removed Unique from PTTC... subclasses need to deal with this

   * PTTC: Renamed a bunch of tests to be more uniform.
   * UR: Added rewrite_attrasgn to normalize arg array into arglist.
   * UR: Added rewrite_op_asgn1 to ensure the arglist is an arglist.
   * UR: Flattened resbodies in rescue node.

   * UR: Rewrote argscat to be a splat inside an array.
   * UR: Rewrote block_pass into arglist of inner call/super.
   * UR: Rewrote call to ALWAYS have an argslist (no more splat as

   * UR: Rewrote rewrite_resbody from scratch... MUUCH cleaner.
   * UR: zarray -> array
   * Used Hoe#add_include_dirs to clean up rakefile.
   * Moved PT dependent code from ruby2ruby to here (eg Proc#to_sexp &
