  42 **  REST FOR REPAIRS
  43 **
  44 **      You sit around and wait for repairs to happen.  Actually, you
  45 **      sit around and wait for anything to happen.  I do want to point
  46 **      out however, that Klingons are not as patient as you are, and
  47 **      they tend to attack you while you are resting.
  48 **
  49 **      You can never rest through a long range tractor beam.
  50 **
  51 **      In events() you will be given an opportunity to cancel the
  52 **      rest period if anything momentous happens.
