ParseTree version 2.0.2 has been released!

* <http://www.zenspider.com/ZSS/Products/ParseTree/>

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]]]]]

* Uses RubyInline, so it just drops in.
* Includes SexpProcessor and CompositeSexpProcessor.
   * Allows you to write very clean filters.
* Includes UnifiedRuby, allowing you to automatically rewrite ruby  
quirks.
* ParseTree#parse_tree_for_string lets you parse arbitrary strings of  
ruby.
* Includes parse_tree_show, which lets you quickly snoop code.
   * echo "1+1" | parse_tree_show -f for quick snippet output.
* Includes parse_tree_abc, which lets you get abc metrics on code.
   * abc metrics = numbers of assignments, branches, and calls.
   * whitespace independent metric for method complexity.
* Includes parse_tree_deps, which shows you basic class level  
dependencies.
* Does not work on the core classes, as they are not ruby (yet).

Changes:

* 2 minor enhancements:

   * Deactivated gcc-specific compiler flags unless ENV['ANAL'] or on  
my domain.
   * Minor code cleanup - happier with -pedantic and the like.

* 1 bug fix:

   * FINALLY conquered the splat args bug on certain platforms/versions.
     Special Thanks to Jonas Pfenniger for debugging this and providing
     a patch.
