We have lots of options if we add ARGV. The main reason I want to add it is
so that we can detect the executable name, but we can also do the following,
if we decide to:

1. Don't even build dependency graphs for targets which we can
determine won't be built based on the listed targets

2. Allow our own option format, e.g. with --option-name. We just have to
manufacture a NOTFILE target with the name that the user has supplied
and arrange for some dummy build action so Jam doesn't bark about it.

Anyway, those are just thoughts. The real reason is to be able to implement
Rene's functionality.

Yes, that makes sense.

Great; we should choose a rough development order and start picking off
jobs. Suggestions?
