jlam da09d28be6 Use the stack in a smarter way. Take an argument (perhaps marshalling
several arguments together) from the command line and push it onto the
stack.  Pop the top off the stack, process, and push replacement
arguments onto the stack.  Repeat the last step until no more processing
is done, and we have our final argument to be passed on through to the
rest of the wrapper script.
