How to have shared options

[JohnScottUK]

I have a cli tool that takes multiple commands - like git. How would I define the common options:

my-cli [common-options] command [command-options]
e.g.
my-cli --verbose cmdA --optionA ABCD
my-cli --verbose cmdB --optionB BCDE

I can see how to define command specific options against each command (i.e. optionA and optionB), but how to I create common options like --verbose?

In my specific case, I wanted to have --verbose change the logging level to verbose and --debug change the logging level to debugging.

I believe this discussion and this issue will help determine how this can work
