Yes... but no. The doc explains you can do this:

my-script (-b VALUE-B | -d VALUE-D) 

ie mutally exclusive group with *just* *one* option incompatible with another one.

But, apparently, you can't do that:

my-script (-a -b VALUE-B | -c -d VALUE-D) 

ie mutually exclusive group with one *set* of option*s* incompatible with another *set* of option*s*. This is why I have posted my message. I have read the documentation before to post it. ;-)

I know docopt but I prefer argparse. My script have subcommands and some of them have common options, so I appreciate the parser objects and the inheritance between parser objects (with parents parameter of argparse.ArgumentParser class).
