Lingon is a graphical user interface for creating and editing launchd configuration files for Mac OS X. You can use launchd on a Mac to launch scripts and applications whenever something special happens or at a specific time or periodically. You get all launchd configuration files in a list to the left so you can easily see all and choose which one to edit.
