On the short way, will you require this to be specified by the programmer,
or will it automatically create a short flag from the long flags?

You might also consider using the any_function stuff as well.

This is very handy to have and if done so that "help" is required when you
register the option it will remind programmers to fill in at least a token
help statement.
