Practical Common Lisp - Crawling InterfaceLift with Common Lisp - second try. Interesting run through a simple project in Common Lisp using Quicklisp. It really makes a lot of things easier than if you program raw in CL and manage all the packages and systems by hand. However, you should not necessarily run the example script, as it violates the terms of use of InterfaceLift (and is not really nice to their servers).
