bazel has arrived at $WORK and it has been a non-trivial amount of work for even the passionate advocates of bazel. I know it was written by the Very Smart People at google. They are clearly smarter than me so I must be the dummy. Especially since I never passed their interview tests. :-)
Of course given all things google, by the time I'm fully onboard the train, the cool kids will be making a new train and then I'll have to hop onto that way to enjoy the rewards of the promised land that never quite seem to arrive.
