Initial commit of OpenSPARC T2 architecture model.

# This file is executed when the Pmw package is imported.  It creates
# a lazy importer/dynamic loader for Pmw and replaces the Pmw module
# with it.  Even though the loader from the most recent installed
# version of Pmw is used, the user is able to specify which version of
# Pmw megawidgets to load by using the setversion() function of the
# loader.

# This is the only file in Pmw which is not part of a particular Pmw
# release.
