# 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

#
