The resources of a widget are filled in from the following places (from
highest priority to lowest priority):

	1. Args passed at creation time.
	2. Command line arguments.
	3. User's per host defaults file
	4. User's defaults file.
	5. User's per application default file.
	6. System wide per application default file.

Note that 2-6 are read only once on application startup.  The result of steps
3-6 is a single resource database used for further queries.

Please see the comp.windows.x.intrinsics FAQ, from which this information is
abstracted, for a full explanation of how to specify the location of files;
see also a good book on Xt, such as ORA's Volume 4, the Asente/Swick book, or
the Xt documentation, for more information.
