Arg decoding with a template?

[Dale Strickland-Clark]

Is there a class that simplifies high-level argument decoding under the control of a template?

Such a class would take a string as a template and the arg list and return another list populated
with keys, values and switches taken from the args.

I've spent the last hour going through the global module list. If it's there, its got a daft name!
