  47 **  DOCK TO STARBASE
  48 **
  49 **      The starship is docked to a starbase.  For this to work you
  50 **      must be adjacent to a starbase.
  51 **
  52 **      You get your supplies replenished and your captives are
  53 **      disembarked.  Note that your score is updated now, not when
  54 **      you actually take the captives.
  55 **
  56 **      Any repairs that need to be done are rescheduled to take
  57 **      place sooner.  This provides for the faster repairs when you
  58 **      are docked.
