040/**
041 An application that sets the look and feel to the native look
042 and feel and then reads one or more
043 files specified on the command line, or instantiates one or
044 more Java classes specified by the -class option.
045
046 <p>This class sets the look and feel of the user interface (UI) to
047 the native look and feel.  Thus, this class invokes Java's user
048 interface code which means that this class should be run in an
049 environment that has a display.  To run in a environment
050 that has no display, see the {@link ptolemy.actor.gui.ConfigurationApplication}
051 parent class.
052
053 <p>For complete usage, see the {@link ptolemy.actor.gui.ConfigurationApplication}
054 parent class.
