     41  * Revision 7.0.1.3  86/12/12  17:07:44  lwall
     42  * Baseline for net release.
     43  *
     44  * Revision 7.0.1.2  86/10/20  12:08:00  lwall
     45  * Made all exits reset tty.
     46  *
     47  * Revision 7.0.1.1  86/10/16  10:54:13  lwall
     48  * Added Damage.  Fixed random bugs.
     49  *
     50  * Revision 7.0  86/10/08  15:14:47  lwall
     51  * Split into separate files.  Added amoebas and pirates.
     52  *
     53  * Revision 6.4  83/12/16  13:11:45  lwall
     54  * Handled 15 bit random number generators.
     55  *
     56  * Fixed array overflow bug on multiple zaps.
     57  *
     58  * Multiple zaps now consolidated to minimize output.
     59  *
     60  * Tholian jackpot games outlawed under difficulty 15.
     61  *
     62  * Revision 6.3  83/08/24  11:17:49  lwall
     63  * Fixed array overflow bug on multiple zap.
     64  *
     65  * Revision 6.2  83/08/23  18:06:37  lwall
     66  * Added zap command.
     67  * Warp -s should now work on dumb terminals
     68  * Specifying difficulty >= 40 now just makes it a special game.
     69  * SIGTTOU #ifdef'ed.
     70  * No-delay read provided as alternative to FIONREAD.
     71  * Warp won't report "-1 obsolete" when there are no Enterprises left.
     72  * Some high-difficulty tuning.
     73  *
     74  * Revision 6.1  83/08/17  08:49:03  lwall
     75  * Fixed obscure bug in storing UP that caused a %. in CM to occasionally
     76  * foist garbage onto the screen.
     77  *
     78  * Revision 6.0  83/08/08  17:09:26  lwall
     79  * New baseline version for net release.
     80  *
     81  * Revision 5.5  83/08/01  10:59:56  lwall
     82  * Cloaking for the Enterprise.
     83  * Difficulty now goes to 99, and many activities depending on difficulty
     84  *     have been adjusted in frequency.
     85  * Simplified exit sequence, and reduced dependencies on control
     86  *     characters.  You needn't see the scoreboard if you don't want to.
     87  * Hitting i,w,c, or v switches to Enterprise.  Hitting p switches to Base.
     88  * Excessive use of q is not allowed.
     89  * Excessive use of D is not allowed.
     90  * Scoreboard may depend on either full name or login name.
     91  * Integrated scoreboard lister.  Login name now shows up on scoreboard.
     92  * "Hidden" startup options are now upper case.
     93  * Checks upon startup for no cursor movement, or screen too small.
     94  * Checks upon startup that WARPDIR is correctly protected, and that warp
     95  *     is running setuid.  As an additional bonus this prevents root from
     96  *     running warp, which mucks things up, UN*X be blessed.
     97  * All gets's turned into fgets's for safety.
     98  * Bonus Enterprises and Bases.
     99  * Escalating bonuses for saving Base and Enterprise.
    100  * Escalating Enterprise energy.
    101  * Turbolasers decrease with distance.
    102  * Really smart enemies can see through stars occasionally.
    103  * Occasional Tholian jackpot waves.  Tholians are a trifle nastier.
    104  * Choleric Gorns.
    105  * An O or o can miss seeing you.  Enemies can avoid a stationary O, o, or X.
    106  * Warp 3 enemies and other nastinesses are possible in massacre mode.
    107  * Enemies that decide to navigate when they see you can do other things than
    108  *     just come toward you.
    109  * Gorns occasionally launch a salvo for the fun of it.
    110  * Only star and enemy explosions can keep the round going now.
    111  * Bounces don't always go back to starting spot now.
    112  * Better full name processing.  USG quirks handled.  & substitution also
    113  *     handled now (whoever dreamed up that one must have been in the middle
    114  *     of the night before the morning after).
    115  * Catch ^D on fgets.
    116  * Version number printer.
    117  * Less signal catching during debugging.
    118  *
    119  * Revision 5.4  83/06/24  09:28:38  lwall
    120  * 16 bit random number generators are now supported.
    121  * Made warp not blow up on a null save file.
    122  * Warp now prints E and B before the stars.
    123  * Fixed bug which caused torp count to get decremented even when no torp
    124  *     was launched because of an obstacle.
    125  * Put %<n>ld formats where appropriate.
    126  * Fixed E: 0  0 bug on refresh.
    127  *
    128  * Revision 5.3  83/05/24  14:03:10  lwall
    129  * Starting RCS
