Hi,

I am writing a program for the command-line which uses 'argsparse'.  I
want to make some options mandatory by setting 'required=True', but
still allow the program to run with the option '--version' (which just
shows the version and then exits) even if the mandatory options are
missing.

Is there a standard way of doing this?

Cheers,

Loris
