Chef and Jenkins

I create chef bits that create jenkins build jobs.  This way I can "create the thing that creates the things."  I can reset the state of things by rm -rf *-config.xml jobs/* on the jenkins server, restart jenkins, then run chef-client and everything gets put back together automatically.  This also allows me to change the run jobs in real time, but then reset everything when I'm done.
