This is the QooxDoo-part of the framework. Usually you don't need to touch this. If you want to help with the developement of this part, please get a copy of the framework at http://qooxdoo.org and put it into source/qooxdoo-1.3-sdk Then you can do ./generate.py build for a binary-build, or ./generate.py clean ./generate.py source for a source-build, which helps for some faster development. Every time you switch from source to build or vice versa, you have to "clean", and then restart the Framework. It will detect automatically which of the two (source or build) is active.
