I have made a note to add Michael Schmahl's concise statement to the
rules, i.e., A catapult can launch a piece occupying it to an empty square
on the same rank or file. It cannnot launch diagonally. Note that the
rules do have examples of legal Catapult moves and launches. On a
different note, a reminder that the first checkmate problem has an
error... the Catapult on E2 should have a Pawn on it.
