so i'm in the process of testing all the install/update scenarios with Package Maker to make sure my versioning is working, and things like that. the problem is, after i've gone through a few test update iterations, i want to start the whole process over, but i can't figure out how. dragging the .app to the trash can doesn't suffice. i remember reading about receipts, but i don't want to just go in and start deleting stuff like that, unless i know what effect it'll have. can anyone tell me what i need to do here? again, this is for my personal testing - i'm not trying to build an uninstaller.
