* ------------------------------------------------------------------------ *
*  The MUDprograms are heavily based on the original MOBprogram code that  *
*  was written by N'Atas-ha.						   *
*  Much has been added, including the capability to put a "program" on     *
*  rooms and objects, not to mention many more triggers and ifchecks, as   *
*  well as "script" support.						   *
*                                                                          *
*  Error reporting has been changed to specify whether the offending       *
*  program is on a mob, a room or and object, along with the vnum.         *
*                                                                          *
*  Mudprog parsing has been rewritten (in mprog_driver). Mprog_process_if  *
*  and mprog_process_cmnd have been removed, mprog_do_command is new.      *
*  Full support for nested ifs is in.                                      *
