 * Revision 2.2  85/08/06  22:29:49  matt
 * Change handling of "r", "b", "g", "j", "q" commands to
 * provide better feedback, using per-player message buffer.
 * 
 * Revision 2.1  85/04/10  17:32:03  matt
 * Major de-linting and minor restructuring.
 * 
 * Revision 1.4  85/02/11  12:44:06  matt
 * added GUTS mode
 * 
 * Revision 1.3  84/07/08  13:40:29  matt
 * Added two bytes of padding to the t_file structure.  Vax compiler
 * added them implicitly but Sun compiler did not, giving "bad new
 * player read".
 * 
 * Revision 1.2  84/07/07  18:11:31  matt
 * Rearranged structure t_file because it gets sent across the
 * net and may be padded differently by different compilers.
