If you ever find yourself in a foreign code base and want to get a quick overview of exactly how much code is in it, CLOC is just the tool for the job.
It’s easy to install on OS X:
$ brew install cloc

$ aptitude install cloc
To use it, simply

$ cloc .

You can, of course, customize the poop out of it as well.
cloc --help to nerd out.
