However,
- you're not building them from scratch
- you don't keep a record of which commits could build
- AFAIK you don't check the logs daily -- at least, I haven't seen
  you emailing -devel saying "somebody broke git master between
  ab12345 and ef6787"

If somebody breaks git master, I don't want anybody to find out
because their build failed.  I want an automatic script to
discover the failing, and tell me BEFORE I try to do any work.
Granted, there's a trade-off between compiling every single commit
vs. available computer power, but I still wish that nobody was
ever surprised that git master failed to compile.


This script is also the first step towards an automatic
dev/staging branch, but I want the basics tested before I move
ahead to work on that stuff.
