hello-lisp is an example of how to lay out the file structure of a Lisp program/library to use asdf and make it asdf-install-friendly.

Note that there is a more recent guide to laying out Lisp projects to be compatible with asdf2 and installable from Quicklisp written by Zach Beane: http://xach.livejournal.com/278047.html
