Modify usage according to contraints

Anonymous — Tue, 27 Jun 2006 20:06:40 -0000

Hi,

I was wondering if it would be possible to have the
displayed usage tailored according to the contraints added?

For example, if I have my 'program', with a mandatory
option called 'name' and execute it like this:

bash#program

I get the message:

error: option 'name' is required. Exiting.
Usage: program [-n|--name <arg>]

Since 'name' is not optional, ideally the usage would show:

error: option 'name' is required. Exiting.
Usage: program -n|--name <arg>

You could imagine more complicated scenarios when at
last one option of a group is mandatory.

Thanks,
JP
