The remove-trigger command removes a trigger which belong to your Unix
user. If your Unix user is root, you can remove the trigger of another
user with the --owner-uid option.
See the “EXAMPLES” section below for usage examples.

Remove the trigger named NAME of the Unix user having the user ID
UID.
You may only use this option if your Unix user is root.
