Rar on Mac OSX

I just downloaded a .rar file onto my Mac and of course it didn't understand it. So off I went to google and looked for something that could extract it. I found a lot of proprietary stuff but nothing really I liked. If you are looking for a funky GUI what you probably are if you are using a Mac you should have a look at http://wakaba.c3.cx/s/apps/unarchiver.html which seams to be a good choice. But I didn't want another program that would integrate itself everywhere and in the end might cause my computer to crash every 25 min. (The Windows application syndrome). But all this looking around took me about 15 minutes till I had the feeling to have looked at all the options. Then I fired up a good old shell and had a look what fink had to offer. And after 1 line I could unrar my file
$ fink install unrar
That was it. I still love the command line, even if I have a funky desktop.
