+** 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. It is probably defined in
+** the version that you get. It can be removed, however, if you
+** have trouble finding room in core.
+**
+** Many things in trek are not as clear as they might be, but are
+** done to reduce space. I compile with the -f and -O flags. I
+** am constrained to running with non-seperated I/D space, since
+** we don't have floating point hardware here; even if we did, I
+** would like trek to be available to the large number of people
+** who either have an 11/40 or do not have FP hardware. I also
+** found it desirable to make the code run reentrant, so this
+** added even more space constraints.
+**
+** I use the portable C library to do my I/O. This is done be-
+** cause I wanted the game easily transportable to other C
+** implementations, and because I was too lazy to do the floating
+** point input myself. Little did I know. The portable C library
+** released by Bell Labs has more bugs than you would believe, so
+** I ended up rewriting the whole blessed thing. Trek excercises
+** many of the bugs in it, as well as bugs in some of the section
+** III UNIX routines. We have fixed them here. One main problem
+** was a bug in alloc() that caused it to always ask for a large
+** hunk of memory, which worked fine unless you were almost out,
+** which I inevitably was. If you want the code for all of this
+** stuff, it is also available through me.
