Dunno, I think it looks pretty nice once rendered. Makes it
straightforward for a user to copy+paste. I asked Rong explicitly to
make sure the documentation made it so that non-googler or folks not
working on autofdo or propellor could reproduce (since we'll probably
end up standing up CI for these newer configs, and BOLT).
