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

* is the general command line structure. All arguements have three
* 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:
*
* argchoice:Argument_label:Argument_method
