/**
* A PackageManager maintains a persistent store of
* package-prefix lists. A package prefix specifies the
* prefix for a complete class name. A factory uses
* a package-prefix list to find a class that
* might belong to any of the packages that are referenced
* in the prefix list.
*
* The Manager uses package-prefix lists
* to find protocol handlers and content handlers for time-based
* media.
*
* The current version of a package-prefix list is obtained with
* the get<package-prefix>List method. This method returns the prefix
* list in use; any changes to the list take effect immediately.
*
* Unless it is made persistent with
* commit<package-prefix>List, a package-prefix list is only valid
* while the Manager is referenced.
*
* The commit<package-prefix>List method ensures that any changes made
* to a package-prefix list are still visible the next time that
* the Manager is referenced.
*
* @see Manager
* @version 1.11, 97/08/23.
