 watcherd will look for directory changes (added and deleted directories) under the specified path (`-p`) and will execute specified commands or shell scripts (`-a`, `-d`) depending on the event.
 Once all events have happened during one round (`-i`), a trigger command can be executed (`-t`).
 Note, the trigger command will only be execute when at least one add or delete command has succeeded with exit code 0.
