*	The basic idea is to replace all of the symbols in the method

*	parts, a label, a method, and a value.  The method never changes, and
*	is used to represent '-flag's for a given function.  Values are the 
*	associated arguements that some flags require.  All symbols that 
*	require argvalue replacement should have a '$' infront of the symbol
*	name in the itemmethod definition.  All symbols without the '$' will
*	be replaced by their argmethod.  There is currently no way to do a label
*	replacement, as the label is considered to be for use in the dialog
*	box only.  An example command line replacement would be:
*
*		itemmethod=> 		"lpr arg1 $arg1 $arg2"
*
*		arglabel arg1=>		"To printer?"
*		argmethod arg1=>	"-P"
*		argvalue arg1=>		"lw"
*
*		arglabel arg2=>		"File name?"
*		argvalue arg2=>		"foobar"
*		argmethod arg2=>	""
*
*	final command line:
*
*		lpr -P lw foobar
*
*	At this point, the chooser dialog type only supports the arglabel and
*	argmethod field.  So if an argument is of type chooser, and
*	its symbol is "this", then "$this" has no real meaning in the
*	itemmethod definition.  Its format in the .GDEmenu file is slighty
*	different as well.  A choice from a chooser field looks like:
