[QUOTE]\nThat is pretty cool. It's the upside of the "tarball" package system the\nmac can use. Not without it's flaws, but what is?[/QUOTE]\n\nSpeaking of tarballs, here's a little oddity on the Mac. If you have a\ncompressed tarball, say foo.tar.gz, and double-click it, the Mac expands\na copy into foo.tar, and then expands a copy of that into foo. So, you\nend up with foo.tar.gz, foo.tar, and foo.\n\nHowever, if the original file is named foo.tgz, then double-clicking it\njust gives you foo.\n\nThere is a nice touch they did on expanding tarballs (and zip files):\nthey always expand to exactly one item (well, I suppose an empty one\nwould expand to zero items...). That is, if there is either a single\nfile in the tarball or zip, or there is a single directory, you get that\nsingle file or directory. If, however, there are multiple top-level\nitems in the tarball or zip, you get a folder named after the tarball or\nzip file, containing those items.
