Sometimes in applications forms are submitted without any changes being made. This can of course be a waste of bandwidth and processing time on the server. This very simple MooTools class checks the values in a form to see if its values have been modified and returns a result of true or false.

It is now possible and recommended to generate MooTools (and its plugins) yourself using MooTools Packager or MooTools Depender. These libraries combine multiple javascript files into one for single file deployment. Once you understand the convention these libraries use, building a single production file is a breeze. This article focuses on setting up your javascript files for use primarily with Packager.
