Carefully do 1/2 of a Swap Around or Reverse Swap Around. If the "Cross" modifier
has been given, those who come in to the center take opposite hands. The setup
should now be two stars of some kind. Adjust those stars if necessary so that
there is a wave down the middle. In the wave, Swing, Slip, and Cast Off 3/4.
The others, while staying out of the way of the people in the wave, Circulate
twice around the outside.

It may help to be aware that the call starts a lot like Swap the Top, with
the "Reverse" and "Cross" modifiers having the same meaning.
