[Click] Configuration parsing with Args: variable argument list with minimum size?

[Eddie Kohler]

Hi Bart,

What I would do is use Args for the mandatory & optional arguments, but 
rather than end with .complete(), end with .consume(). Then process the 
leftovers however best makes sense.

For an example, see UDPRewriter, which strips off a bunch of keywords 
with Args(this, errh).bind(conf).read........consume().

Make sense?
