- * The monster is known to be within 100 grids of the player\n

- *\n
- * Note that a monster is only allowed to "reproduce" if there\n
- * are a limited number of "reproducing" monsters on the current\n
- * level.  This should prevent the level from being "swamped" by\n
- * reproducing monsters.  It also allows a large mass of mice to\n
- * prevent a louse from multiplying, but this is a small price to\n
- * pay for a simple multiplication method.\n
- *\n
- * XXX Monster fear is slightly odd, in particular, monsters will\n
- * fixate on opening a door even if they cannot open it.  Actually,\n
- * the same thing happens to normal monsters when they hit a door\n
- *\n
- * In addition, monsters which *cannot* open or bash\n
- * down a door will still stand there trying to open it...\n
- *\n
- * XXX Technically, need to check for monster in the way\n
- * combined with that monster being in a wall (or door?)\n
