Subject: Spin model checker 5.2.4

A verification tool for models of concurrent systems.

Manually installing spin on Mac OS X is somewhat cumbersome and requires edits
to the makefile, as as detailed at http://spinroot.com/spin/Man/README.html.
The included DATA patch automates this.

(My thanks to adamv, who pointed out how to simplify this formula greatly.)
