$(help-header USAGE)

$(help-usage "bin/setup")

$(help-usage "bin/setup [ ${action_list} ]")

$(help-header DESCRIPTION:)

Runs full setup without any arguments.

Accepts one optional argument — one of the actions that typically run

as part of setup, with one exception — ${bldylw}remove-git-hook${clr}.

This action removes the git commit hook installed by the setup.

$(help-header EXAMPLES:)

$(help-example "bin/setup")

Or, to run only one of the sub-functions (actions), pass

it as an argument:

$(help-example "bin/setup help")

$(help-example "bin/setup remove-git-hook")

}
