# This demo script prints out a command that summons a spawner minecart with 10
# spawn potentials, each of which is a command block minecart. Each of these
# command block minecarts is numbered `i` from 1 to 10, with a progressively
# greater spawn probability of `i / 55` and a command that prints a message
# including `i`. Note the absolute position of the spawned command block
# minecarts, and the relative position (offset) of the initial spawner minecart.
