 * The file is purged upon normal entry to try to avoid that problem.
 * A similar problem exists for energy voids.  To alleviate the problem here,
 * the void file is cleared with every new king, and a limit is placed
 * on the size of the energy void file.

/*
 * Put one line of text into the file 'motd' for announcements, etc.

/*
 * If ENEMY is #defined, a list of restricted login names is checked

/*
 * The scoreboard file is updated when someone dies, and keeps track
 * of the highest character to date for that login.
 * Being purged from the character file does not cause the scoreboard
