ParseTree version 1.4.1 has been released!

** DESCRIPTION:

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]]]]]

** FEATURES/PROBLEMS:

+ Uses RubyInline, so it just drops in.
+ Includes SexpProcessor and CompositeSexpProcessor.
	+ Allows you to write very clean filters.
+ 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.
+ Only works on methods in classes/modules, not arbitrary code.
+ Does not work on the core classes, as they are not ruby (yet).

Changes:

+ 4 minor enhancements:
	+ parse_tree_show -f output is much cleaner now.
	+ ParseTree does a much more elegant job of handling different  
versions.
	+ ParseTree now has all node names in ParseTree::NODE_NAMES.
	+ ParseTree now raises exceptions instead of freakin'.
+ 3 bug fixes:
	+ Used multiruby to test against 1.8.2-4, 1.8 cvs, and 1.9 cvs.
	+ Fixed incompatibilites introduced in ruby 1.8.4.
	+ Fixed some incompatibilites introduced in ruby 1.9.x.
