Regarding this section of the docs:

          http://icfpc.plt-scheme.org/bdk/#server

My question is on this:
<quote>
To change one of the cops, use --copA, --copB, --copC, --copD, or
--copE, which sets the first, second, third, fourth, or fifth cop,
respectively. For example, the following command uses mycop for two of
the cops in a game:


  % server --robber "myrobber 11" --copB "mycop 7" --copC "mycop 0"

My question is: "what occurs in this case for cops a,d, and e since
nothing is specified" ?
