When I created those documents a long time ago I was trying to make a set of controls that could be used outside of mojoPortal or in mojoPortal. Over time I've come to no longer care about making them useful outside of mojoPortal, though developers could still grab the code and use them, it is just not a goal for me to provide any support beyond mojoPortal..

The best documentation of our controls is the source code itself. Some controls are no longer used and are legacy from older implementations, for example we no longer use ExtJs because they changed their license a long time ago and made it incompatible, so any of the lingering ExtJs controls are legacy, most YUI stuff is no longer used either other than a color picker we still use.
