+# Complex glazing model (goes with glaze1.cal and glaze2.cal)
+#
+# Oct. 2002 Greg Ward
+# Aug. 2004 GW (added -f option to read glazings from file)
+# Funding for this development generously provided by Visarc, Inc.
+# (http://www.visarc.com)
+#
+# Nov. 2009 Jack de Valpine - Visarc, Inc.
+#     -f option now clears the internal demo database and accepts
+#        a clear glass definition as the first entry
+#        in the database file
+#
