Hi Kenneth,

there is some literature on Spec that might help you out.

- The tech report serves as a 'getting started' 
http://hal.inria.fr/docs/00/70/80/67/PDF/SpecTechReport.pdf 
- Also, we published a paper that talks more about the motivations behind spec 
and itsadvantages.http://dl.acm.org/citation.cfm?doid=2448963.2448965 I can 
send you a preprint in a direct message if you are unable to download it.

Greetings,
