'''SPIN''' is a general tool for verifying the correctness of [[concurrency (computer science)|concurrent software]] models in a rigorous and mostly automated fashion. It was written by [[Gerard J. Holzmann]] and others in the original [[Unix]] group of the Computing Sciences Research Center at [[Bell Labs]], beginning in 1980. The software has been available freely since 1991, and continues to evolve to keep pace with new developments in the field.
