/*
 *  hdds-geant :   an interface utility that reads in a HDDS document
 *                   (Hall D Detector Specification) and writes out a
 *                   GEANT-3 geometry description in the form of a
 *                   fortran subroutine.
 *
 *  Revision - Richard Jones, November 25, 2006.
 *   -added output of optical properties for materials with optical
 *    properties defined
 *
 *  Revision - Richard Jones, January 25, 2005.
 *   -added the sphere section as a new supported volume type
 *
 *  Original version - Richard Jones, May 19 2001.
 *
 *  Notes:
 *  ------
 * 1. Output is sent to standard out through the ordinary c++ i/o library.
 * 2. As a by-product of using the DOM parser to access the xml source,
 *    hdds-geant verifies the source against the schema before translating it.
 *    Therefore it may also be used as a validator of the xml specification
 *    (see the -v option).
