/**
* Generate the documentation in the Html "frame" format in the browser. The
* generated documentation will have two or three frames depending upon the
* number of packages on the command line. In general there will be three frames
* 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.
* If you write code that depends on this, you do so at your own risk.
* This code and its internal interfaces are subject to change or
* deletion without notice.
