/**
 * This class provides a mechanism for returning the version number of the
 * pal library. It relies on the administrator of the pal library using the
 * module tagging system in CVS. The method getVersionString() will return
 * the version of the pal library under the following conditions: <BR>
 * 1. the pal library has been tagged with an identifier in the format: 
 * pal-#-# or pal-#-#-#, e.g. pal-1-3-0 for version 1.3.0. 
 * 2. the pal library has been checked out *by tag* before packaged for
 * distribution.
