41 ** call starbase for help
43 ** First, the closest starbase is selected. If there is a
44 ** a starbase in your own quadrant, you are in good shape.
45 ** This distance takes quadrant distances into account only.
47 ** A magic number is computed based on the distance which acts
48 ** as the probability that you will be rematerialized. You
51 ** When it is determined that you should be able to be remater-
52 ** ialized (i.e., when the probability thing mentioned above
53 ** comes up positive), you are put into that quadrant (anywhere).
54 ** Then, we try to see if there is a spot adjacent to the star-
55 ** base. If not, you can't be rematerialized!!! Otherwise,
56 ** it drops you there. It only tries five times to find a spot
57 ** to drop you. After that, it's your problem.
