This package produces a single web page displaying a front end to an ANT based build system. The purpose of the package is to automate the process of calculating dependencies and building YUI 3 incremental rollout files. It leverages YUI3 own loader in order to compute the dependencies, so the result is guaranteed to be the same as you get, using a manually crafted configuration of YUI 3 modules. It works for your own and others' gallery modules and for css files too.
