how do i download source code using svn on OS X?

How can I get source code off the internet using SVN? I'm trying to download Oolong game engine f开发者_StackOverflowor iPhone OS.

I am on Mac OS X 10.6 with XCode 3.2.2.

svn checkout http://oolongengine.googlecode.com/svn/trunk/ oolongengine-read-only

is the command I got from the Oolong Google Code page.

EDIT:

I've tried the command in Terminal. I don't know where the code ends up on my machine. I did not get any errors.

svn ships with Mac OS X, so all you need to do is open Terminal, navigate to the directory where you want the code, then you can copy and paste that line right in to terminal, hit enter, an voila, the code will be checked out on to your machine.
