Notes

• Options to add actions take the argument ACTION, the action name as shown in flagman --list, followed by an action-defined number of arguments, which are also documented in flagman --list. See the output of flagman --help for a more complete view of this.
• All options to add actions for signals may be passed multiple times.
• When a signal with multiple actions is handled, the actions are guaranteed to be taken in the order they were passed on the command line.
• Calling with no actions set is a critical error and will cause an immediate exit with code 2.
