/* Compared to original version, I've changed the "help" command to
   "call" and the "terminate" command to "quit" to better match
   user expectations. The DECUS version apparently made those changes
   as well as changing "freeze" to "save". However I like "freeze".

   When I got a later version of Super Star Trek that I was converting
   from, I added the emexit command.

   That later version also mentions srscan and lrscan working when
   docked (using the starbase's scanners), so I made some changes here
   to do this (and indicating that fact to the player), and then realized
   the base would have a subspace radio as well -- doing a Chart when docked
   updates the star chart, and all radio reports will be heard. The Dock
   command will also give a report if a base is under attack.

   Movecom no longer reports movement if sensors are damaged so you wouldn't
   otherwise know it.

   Also added:

   1. Better base positioning at startup

   2. deathray improvement (but keeping original failure alternatives)

   3. Tholian Web

   4. Enemies can ram the Enterprise. Regular Klingons and Romulans can
      move in Expert and Emeritus games. This code could use improvement.

   5. The deep space probe looks interesting! DECUS version

   6. Cloaking (with contributions from Erik Olofsen) and Capturing (BSD version).
