For stance, take git-state:

git state [view] [--show-all] [--show EXTENSION [EXTENSION ...]]
                 [--no-show EXTENSION [EXTENSION ...]]
                 [--show-empty] [--no-show-empty]
                 [--color [WHEN]] [--no-color]
                 [--pretty] [--format FORMAT]
                 [--clear] [--no-clear] [--no-page]
                 [--order SECTION [SECTION ...]]
                 [--options OPTION [OPTION ...]]
git state extensions create --command COMMAND [--name NAME]
                            [--options OPTIONS] [--no-show]
                            [--no-color] EXTENSION
git state extensions edit [--command COMMAND] [--name NAME]
                          [--options OPTIONS] [--no-show]
                          [--no-color] EXTENSION
git state extensions delete EXTENSION
git state extensions config EXTENSION
git state extensions list
git state extensions run EXTENSION
git state --help
git state --version
