We created a Perl Command line system for Linux that can be used with VVC to help retrofit your Joomla code.
It includes a difference script and code profiler script. It is menu-driven with some documentation, a FAQ, and a support interface. It helps auomate the files VVC identifies, in a batch mode.
It can be downloaded from:
