Writing Common Lisp code that executes from the command line, but not inside the interpreter

Question

When writing Common Lisp code, I use SLIME. In particular, I compile the buffer containing definitions of functions by using C-C C-k, and then switch to the REPL to run thos

Fare Rideau wrote a nifty unix utility CL-Launch, which enables executing lisp software from the command line. It has integrated Quicklisp support and works on most of the Common Lisp implementations.

Example script may look like this:

#!/usr/bin/cl -sp "hunchentoot" -Q -E main

(defun main (argv)
  (format t "~A: ~{~A ~}~%" (truename ".") argv)
  (hunchentoot:start
   (make-instance 'hunchentoot:acceptor
                  :document-root (truename ".")
                  :port 8080))
  (do ((x #\s (read-char)))
      ((char-equal x #\q) nil)))

After adding +x permissions to script and invoking it, it will start http server in the current directory. "-sp" flag indicates package you want to load, so it's fairly clean way of abstracting shell script from the package.
