Does that mean
 if you run it from the source tree in a tree configured
 for out of tree build it will:
 (a) pollute your source tree with test output and binaries
 (b) give you a helpful message about what to do
 (c) magically find the build tree somehow
 (d) not need to write any binaries/test output/temp files at all

?
