I'd like to know how to completely remove programs in Mac OS X. For instance, I have no use for iMovie, iTunes, Mail, etc. and would like to know how to remove them completely. Would simply deleting the package in the Applications folder do the job? Back when I was using Mac OS 9, I knew pretty much what every file in the system folder was and what program they belonged to, but now, I have no idea what most of them do.
