Yeah, we should totally document our buildbot utils somewhere.

I believe the main reason why there aren't any public buildbots is that 
most parties target their own code, i.e. they're more interested in 
fixing false positives that hurt them specifically, and these overlap 
very poorly, given how dramatically different any different codebases 
usually are.

There's a historical attempt at 
- technically it's there but in practice we never got to growing it into 
anything more than an experimental prototype. Also, i heard that Green 
Dragon's CPU power is relatively expensive, so we should go for a 
separate machine if we are to set up a public Static Analyzer reference 
results bot.
