-/* Compared to original version, I've changed the "help" command to\r
-   "call" and the "terminate" command to "quit" to better match\r
-   user expectations. The DECUS version apparently made those changes\r
-   as well as changing "freeze" to "save". However I like "freeze".\r
-\r
-   When I got a later version of Super Star Trek that I was converting\r
-   from, I added the emexit command.\r
-\r
-   That later version also mentions srscan and lrscan working when\r
-   docked (using the starbase's scanners), so I made some changes here\r
-   to do this (and indicating that fact to the player), and then realized\r
-   the base would have a subspace radio as well -- doing a Chart when docked\r
-   updates the star chart, and all radio reports will be heard. The Dock\r
-   command will also give a report if a base is under attack.\r
-\r
-   Movecom no longer reports movement if sensors are damaged so you wouldn't\r
-   otherwise know it.\r
-\r
-   Also added:\r
-\r
-   1. Better base positioning at startup\r
-\r
-   2. deathray improvement (but keeping original failure alternatives)\r
-\r
-   3. Tholian Web\r
-\r
-   4. Enemies can ram the Enterprise. Regular Klingons and Romulans can\r
-      move in Expert and Emeritus games. This code could use improvement.\r
-\r
-   5. The deep space probe looks interesting! DECUS version\r
-\r
-   6. Perhaps cloaking to be added later? BSD version\r

+
+Dave Matuszek says:
+
+   SRSCAN, MOVE, PHASERS, CALL, STATUS, IMPULSE, PHOTONS, ABANDON,
+   LRSCAN, WARP, SHIELDS, DESTRUCT, CHART, REST, DOCK, QUIT, and DAMAGE
+   were in the original non-"super" version.
+
+   Tholians weren't in the original. Dave is dubious about their merits.
+
+   Planets and dilithium crystals weren't in the original.  Dave is OK
+   with this idea. He says the bit about the Galileo getting
+   turned into a McDonald's is "consistant with our original vision".
+
+   Dave also says the Space Thingy should not be preserved across saved
+   games, so you can't prove to others that you've seen it.  He says it
+   shouldn't fire back, either.  It should do nothing except scream and
+   disappear when hit by photon torpedos.  It's OK that it may move
+   when attacked, but it didn't in the original.
+
+   The Faerie Queen, black holes, and time warping were in the original.
+
+Here are Tom Almy's changes:
+
+   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. Perhaps cloaking to be added later? BSD version
+
+Here are Stas Sergeev's changes:
+
+   1. The Space Thingy can be shoved, if you ram it, and can fire back if 
+      fired upon.
+
+   2. The Tholian can be hit with phasers
+
+   3. When you are docked, base covers you with an almost invincible shields 
+      (a commander can still ram you, or a Romulan can destroy the base,
+      or a SCom can even succeed with direct attack IIRC, but this rarely 
+      happens).
+
+   4. SCom can't escape from you if no more enemies remain (without this, 
+      chasing SCom can take an eternity).
+
+   5. Probe target you enter is now the destination quadrant. Before I don't 
+      remember what it was, but it was something I had difficulty using.
+
+   6. Secret password is now autogenerated.
+
+   7. "Plaque" is adjusted for A4 paper :-)
+
+   8. Phasers now tells you how much energy needed, but only if the computer 
+       is alive.
+
+   9. Planets are auto-scanned when you enter the quadrant.
+
+   10. Mining or using crystals in presense of enemy now yields an attack.
+       There are other minor adjustments to what yields an attack
+       and what does not.
+
+   11. Ramming a black hole is no longer instant death.  There is a
+       chance you might get timewarped instead.
+
+   12. "freeze" command reverts to "save", most people will understand this
+        better anyway.
+
+   13. Screen-oriented interface, with sensor scans always up.
+
+Eric Raymond's changes:
+
+ Mainly, I translated this C code out of FORTRAN into C -- created #defines
+   for a lot of magic numbers and refactored the heck out of it.
+
+   1. "sos" and "call" becomes "mayday", "freeze" and "save" are both good.
+
+   2. Status report now indicates when dilithium crystals are on board.
+
+   3. Per Dave Matuszek's remarks, Thingy state is not saved across games.
