- * @brief 全モンスターのターン管理メインルーチン /
- * Process all the "live" monsters, once per game turn.
- * @return なし
- * @details
- * During each game current game turn, we scan through the list of all the "live" monsters,\n
- * (backwards, so we can excise any "freshly dead" monsters), energizing each\n
- * monster, and allowing fully energized monsters to move, attack, pass, etc.\n
- *\n
- * Note that monsters can never move in the monster array (except when the\n
- * "compact_monsters()" function is called by "dungeon()" or "save_player()").\n
- *\n
- * This function is responsible for at least half of the processor time\n
- * on a normal system with a "normal" amount of monsters and a player doing\n
- * normal things.\n
- *\n
- * When the player is resting, virtually 90% of the processor time is spent\n
- * in this function, and its children, "process_monster()" and "make_move()".\n
- *\n
- * Most of the rest of the time is spent in "update_view()" and "lite_spot()",\n
- * especially when the player is running.\n
- *\n
- * Note the special "MFLAG_BORN" flag, which allows us to ignore "fresh"\n
- * monsters while they are still being "born".  A monster is "fresh" only\n
- * during the game turn in which it is created, and we use the "hack_m_idx" to\n
- * determine if the monster is yet to be processed during the game turn.\n
- *\n
- * Note the special "MFLAG_NICE" flag, which allows the player to get one\n
- * move before any "nasty" monsters get to use their spell attacks.\n
- *\n
- * Note that when the "knowledge" about the currently tracked monster\n
- * changes (flags, attacks, spells), we induce a redraw of the monster\n
- * recall window.\n
