The SPIN Model Checker is used for both teaching software verification

techniques, and for validating large scale applications. The growing number of

users has created a need for a more comprehensive user guide and a standard

reference manual that describes the most recent version of the tool. This book

fills that need.

SPIN is used in over 40 countries. The offical SPIN web site, spinroot.com

receives between 2500 and 3000 hits per day.

It has been estimated that up to three-quarters of the $400 billion spent

annually to hire programmers in the United States is ultimately spent on

debugging.
