 /*
  *  Adding new mextra structures:
  *
  *       1. Add the structure definition and any required macros in this
  *          file above the mextra struct.
  *       2. Add a pointer to your new struct to the mextra struct in this
  *          file.
  *       3. Add a referencing macro at bottom of this file after the mextra
  *          struct (see MNAME, EGD, EPRI, ESHK, EMIN, or EDOG for examples).
  *       4. Create a newXX(mtmp) function and possibly a free_XX(mtmp)
  *          function in an appropriate new or existing source file and add
  *          a prototype for it to include/extern.h.
  *
  *              void FDECL(newXX, (struct monst *));
  *              void FDECL(free_XX, (struct monst *));
  *
  *              void
  *              newXX(mtmp)
  *              struct monst *mtmp;
  *              {
  *                  if (!mtmp->mextra)
  *                      mtmp->mextra = newmextra();
  *                  if (!XX(mtmp)) {
  *                      XX(mtmp) = (struct XX *) alloc(sizeof (struct XX));
  *                      (void) memset((genericptr_t) XX(mtmp),
  *                                    0, sizeof (struct XX));
  *                  }
  *              }
  *
  *       5. Consider adding a new makemon flag MM_XX flag to include/hack.h
  *          and a corresponding change to makemon() if you require your
  *          structure to be added at monster creation time.  Initialize your
  *          struct after a successful return from makemon().
  *
  *              src/makemon.c:  if (mmflags & MM_XX) newXX(mtmp);
  *              your new code:  mon = makemon(&mons[mnum], x, y, MM_XX);
  *
  *       6. Adjust size_monst() in src/cmd.c appropriately.
  *       7. Adjust dealloc_mextra() in src/mon.c to clean up
  *          properly during monst deallocation.
  *       8. Adjust copy_mextra() in src/mon.c to make duplicate
  *          copies of your struct or data on another monst struct.
  *       9. Adjust restmon() in src/restore.c to deal with your
  *          struct or data during a restore.
  *      10. Adjust savemon() in src/save.c to deal with your
  *          struct or data during a save.
