/**
* Generate the documentation in the Html "frame" format in the browser. The

* in the output, a left-hand top frame will have a list of all packages with
* links to target left-hand bottom frame. The left-hand bottom frame will have
* the particular package contents or the all-classes list, where as the single
* right-hand frame will have overview or package summary or class file. Also
* take care of browsers which do not support Html frames.
*
* This is NOT part of any supported API.
