**
** C version by Eric P. Allman 5/76 (U.C. Berkeley) with help
** from Jeff Poskanzer and Pete Rubinstein.
**
** I also want to thank everyone here at Berkeley who
** where crazy enough to play the undebugged game. I want to
** particularly thank Nick Whyte, who made considerable
** suggestions regarding the content of the game. Why, I'll
** never forget the time he suggested the name for the
** "capture" command.
**
** Please send comments, questions, and suggestions about this
** game to:
** Eric P. Allman
** Project INGRES
** Electronics Research Laboratory
** Cory Hall
** University of California
** Berkeley, California 94720
**
** If you make ANY changes in the game, I sure would like to
** know about them. It is sort of an ongoing project for me,
** and I very much want to put in any bug fixes and improvements
** that you might come up with.
**
** FORTRASH version by Kay R. Fisher (DEC) "and countless others".
** That was adapted from the "original BASIC program" (ha!) by
** Mike Mayfield (Centerline Engineering).
**
** Additional inspiration taken from FORTRAN version by
** David Matuszek and Paul Reynolds which runs on the CDC
** 7600 at Lawrence Berkeley Lab, maintained there by
** Andy Davidson. This version is also available at LLL
** and at LMSC. In all fairness, this version was the
** major inspiration for this version of the game (trans-
** lation: I ripped off a whole lot of code).
**
** Minor other input from the "Battelle Version 7A" by Joe Miller
** (Graphics Systems Group, Battelle-Columbus Labs) and
** Ross Pavlac (Systems Programmer, Battelle Memorial
** Institute). That version was written in December '74
** and extensively modified June '75. It was adapted
** from the FTN version by Ron Williams of CDC Sunnyvale,
** which was adapted from the Basic version distributed
** by DEC. It also had "neat stuff swiped" from T. T.
** Terry and Jim Korp (University of Texas), Hicks (Penn
** U.), and Rick Maus (Georgia Tech). Unfortunately, it
** was not as readable as it could have been and so the
** translation effort was severely hampered. None the
** less, I got the idea of inhabited starsystems from this
** version.
**
** Permission is given for use, copying, and modification of
** all or part of this program and related documentation,
** provided that all reference to the authors are maintained.

** NOTES TO THE MAINTAINER:
**
** There is a compilation option xTRACE which must be set for any
** trace information to be generated (the -t option must also be
** set on the command line). It is no longer defined by default.
