I'm been a big fan of making custom cron files for years in both Linux and OS X. As many of you know, Tiger replaced cron and some other things with launchd. I can't figure out how to add/edit/delete scheduled events. I've googled launchd and I haven't found a good manual on launchd that I've got to work. Even 'man launchd' sucks. Anyone have any knowledge on this?
