This program is an "inotify cron" system. It consists of a daemon and a table manipulator. You can use it a similar way as the regular cron. The difference is that the inotify cron handles filesystem events rather than time periods. Written to use (and named after) Linux' "inotify", on BSD it uses the libinotify compatibility layer.
