-/* Cave closing and scoring */

-
-/* These sections handle the closing of the cave. The cave closes "clock1"
- * turns after the last treasure has been located (including the pirate's
- * chest, which may of course never show up). Note that the treasures need not
- * have been taken yet, just located. Hence clock1 must be large enough to get
- * out of the cave (it only ticks while inside the cave). When it hits zero,
- * we branch to 10000 to start closing the cave, and then sit back and wait for
- * him to try to get out. If he doesn't within clock2 turns, we close the
- * cave; if he does try, we assume he panics, and give him a few additional
- * turns to get frantic before we close. When clock2 hits zero, we branch to
- * 11000 to transport him into the final puzzle. Note that the puzzle depends
- * upon all sorts of random things. For instance, there must be no water or
- * oil, since there are beanstalks which we don't want to be able to water,
- * since the code can't handle it. Also, we can have no keys, since there is a
- * grate (having moved the fixed object!) there separating him from all the
- * treasures. Most of these problems arise from the use of negative prop
- * numbers to suppress the object descriptions until he's actually moved the
- * objects. */
-
-/* When the first warning comes, we lock the grate, destroy the bridge, kill
- * all the dwarves (and the pirate), remove the troll and bear (unless dead),
- * and set "closng" to true. Leave the dragon; too much trouble to move it.
- * from now until clock2 runs out, he cannot unlock the grate, move to any
- * location outside the cave, or create the bridge. Nor can he be
- * resurrected if he dies. Note that the snake is already gone, since he got
- * to the treasure accessible only via the hall of the mountain king. Also, he's
- * been in giant room (to get eggs), so we can refer to it. Also also, he's
- * gotten the pearl, so we know the bivalve is an oyster. *And*, the dwarves
- * must have been activated, since we've found chest. */
