LingonIn Mac OS/X Tiger, Apple introduced a new type of system startup called launchd, which replaces many tasks traditionally run by either process number 1 (init) or cron. launchd is controlled by property files (XML) which can be daunting to write. Enter Lingon, a free tool by Peter Borg which allows to easily create new and modify existing launchd property files. An indispensable tool for anybody who wants to tweak launchd.
