Solution in Common Lisp to the tutorial exercice on measurement 1009150.

Requires a Common Lisp (tested with SBCL) and CL-JSON.

SBCL
http://www.sbcl.org/
Steel Bank Common Lisp (SBCL) is a high performance Common Lisp compiler.

Quicklisp
http://www.quicklisp.org/
Quicklisp makes it easy to get started with a rich set of
community-developed Common Lisp libraries

CL-JSON
http://common-lisp.net/project/cl-json/
CL-JSON provides an encoder of Lisp objects to JSON format and a
corresponding decoder of JSON data to Lisp objects.

Installing SBCL, Quicklisp and CL-JSON on Debian:

    sudo aptitude install sbcl cl-quicklisp
    sbcl --load /usr/share/cl-quicklisp/quicklisp.lisp \
	 --eval '(quicklisp-quickstart:install)' \
	 --eval '(ql:quickload "cl-json")' \
	 --quit

Running with SBCL and Quicklisp:

    sbcl --load ~/quicklisp/setup.lisp \
         --script exercice-ping-1009150-lisp.lisp
