This class acts as an artificial PackageDoc for classes specified
on the command line when running Javadoc.  For example, if you
specify several classes from package java.lang, this class will catalog
those classes so that we can retrieve all of the classes from a particular
package later.
 
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
