This directory contains "widget description" files, to be used to add
extra widgets to tclMotif. Suppose the widget is "foo". There will be
a file (that might as well be called "foo") that contains lines of info
such as:

	command			xmFoo
	class			fooWidgetClass
	create-function		Tm_AnyCmd
	method-function		Tm_AnyWidgetCmd
	include-file		<foo.h>
	reason			XmCR_ANCHOR	anchor
	reason			XmCR_HTTP	http
	library			-lfoo
	include-dir		/usr/local/include/foo

There may also be files

	foo.expand
	foo.initialise
	foo.commands

The first contains code to handle percent expansion.
The second contains additional initialisation code for the widget.
The third contains any additional code for widget creation and
method handling.
