 **[watcherd](https://github.com/devilbox/watcherp/blob/master/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`).
