  13.   *  Adding new mextra structures:
  14.   *
  15.   *	 1. Add the structure definition and any required macros in this file
  16.   *	    above the mextra struct.
  17.   *	 2. Add a pointer to your new struct to the mextra struct in this
  18.   *file.
  19.   *	 3. Add a referencing macro at the bottom of this file after the
  20.   *mextra
  21.   *	    struct (see MNAME, EGD, EPRI, ESHK, EMIN, or EDOG for examples).
  22.   *	 4. Create a newXX(mtmp) function and possibly a free_XX(mtmp)
  23.   *function
  24.   *	    in an appropriate new or existing source file and add a prototype
  25.   *	    for it to include/extern.h.
  26.   *
  27.   *		void FDECL(newXX, (struct monst *));
  28.   *	        void FDECL(free_XX, (struct monst *));
  29.   *
  30.   *	          void
  31.   *	          newXX(mtmp)
  32.   *	          struct monst *mtmp;
  33.   *	          {
  34.   *	              if (!mtmp->mextra) mtmp->mextra = newmextra();
  35.   *	              if (!XX(mtmp)) {
  36.   *	                  XX(mtmp) = (struct XX *)alloc(sizeof(struct XX));
  37.   *	                  (void) memset((genericptr_t) XX(mtmp),
  38.   *	                             0, sizeof(struct XX));
  39.   *	              }
  40.   *	          }
  41.   *
  42.   *	 5. Consider adding a new makemon flag MM_XX flag to include/hack.h
  43.   *and
  44.   *	    a corresponding change to makemon() if you require your structure
  45.   *	    to be added at monster creation time. Initialize your struct
  46.   *	    after a successful return from makemon().
  47.   *
  48.   *	     src/makemon.c:  if (mmflags & MM_XX) newXX(mtmp);
  49.   *	     your new code:  mon = makemon(&mons[mnum], x, y, MM_XX);
  50.   *
  51.   *	 6. Adjust size_monst() in src/cmd.c appropriately.
  52.   *	 7. Adjust dealloc_mextra() in src/mon.c to clean up
  53.   *	    properly during monst deallocation.
  54.   *	 8. Adjust copy_mextra() in src/mon.c to make duplicate
  55.   *	    copies of your struct or data on another monst struct.
  56.   *	 9. Adjust restmon() in src/restore.c to deal with your
  57.   *	    struct or data during a restore.
  58.   *	10. Adjust savemon() in src/save.c to deal with your
  59.   *	    struct or data during a save.
