/* Revision 1.1  2020/11/09 23:37:05  kamil
/* Add Warp Kit, Version 7.0 by Larry Wall
/*
/* Warp is a real-time space war game that doesn't get boring very quickly.
/* Read warp.doc and the manual page for more information.
/*
/* games/warp originally distributed with 4.3BSD-Reno, is back to the BSD
/* world via NetBSD. Its remnants were still mentioned in games/Makefile.
/*
/* Larry Wall, the original author and the copyright holder, generously
/* donated the game and copyright to The NetBSD Foundation, Inc.
/*
/* Import the game sources as-is from 4.3BSD-Reno, with the cession
/* of the copyright and license to BSD-2-clause NetBSD-style.
/*
/* Signed-off-by: Larry Wall <larry (at) wall.org>
/* Signed-off-by: Kamil Rytarowski <kamil (at) netbsd.org>
/*
 * Revision 7.0.1.2  86/12/12  17:08:42  lwall
 * Baseline for net release.
 *
 * Revision 7.0.1.1  86/10/16  10:54:26  lwall
 * Added Damage.  Fixed random bugs.
 *
 * Revision 7.0  86/10/08  15:17:55  lwall
 * Split into separate files.  Added amoebas and pirates.

/* WARPLIB must be readable and writeable by warp, but not by anyone who you
 * don't trust.  In other words, to set up warp so everyone can play and
 * no one can cheat, give warp a uid of its own and make warp setuid to
 * that uid.  WARPLIB must then NOT be made writeable by the world,
 * since no attempt is made to encrypt saved games or anything.
 * (It must be readable by the world, however, due to a strangeness in
 * access.)

 * new_position = (current_position + delta + ?SIZE00) % ?SIZE
 * This allows for negative deltas of up to ?SIZE00 (% doesn't work right
 * on negative numbers).
