This javascript-based patch analyses and makes statistics on the content of another patch. It is a small part of a project involving the maintenance of a big corpus of max-based works, where we need to estimate automatically the complexity of the patches, in term of size, deepness, level of abstraction, presence of third party objects, comments density, etc. You can add it to the "Extras" folder (together with the javascript source). Don't hesitate to contact me (lemouton@ircam.fr) if you find it useful or have any kind of suggestion about this project.
