If I'm understanding you correctly, it's already available.
Search for "Negatable flags" in the README. You can declare an option like this:
option "--[no-]foo", :flag, "...", :default => true
and Clamp will happily accept both "--foo" and "--no-foo" arguments.
If you prefer, you could implement the variant that took an argument like this:
option "--foo", "YES/NO", "...", :default => true do |arg|
%w(true yes on).include?(arg.downcase)
end
from clamp.
Ahha, so it's already available! The '--[no-]foo' stuff is exactly what I was looking for.

Also, thanks for pointing out the readme section, not sure how I missed that before :)
