# The first expression is evaluated once, before the loop is entered.
# Usually used for assignments.  You could put more than one, separated
# by commas, but that's almost never done.

# The second is a condition.  Whenever it's true, it continues looping.
# If you put 0, the inner loop would never be executed at all.  If you put 1, it'd loop forever.

# The third expression is evaluated after every loop.  Usually used to
# increase a value but you could put any expression there.

# the do/done section is just like a while.
