/*  DESCRIPTION OF THE DATABASE FORMAT

 *

 *

 *  THE DATA FILE CONTAINS SEVERAL SECTIONS.  EACH BEGINS WITH A LINE CONTAINING

 *  A NUMBER IDENTIFYING THE SECTION, AND ENDS WITH A LINE CONTAINING "-1".

 *

 *  SECTION 1: LONG FORM DESCRIPTIONS.  EACH LINE CONTAINS A LOCATION NUMBER,

 *      A TAB, AND A LINE OF TEXT.  THE SET OF (NECESSARILY ADJACENT) LINES

 *      WHOSE NUMBERS ARE X FORM THE LONG DESCRIPTION OF LOCATION X.

 *  SECTION 2: SHORT FORM DESCRIPTIONS.  SAME FORMAT AS LONG FORM.  NOT ALL

 *      PLACES HAVE SHORT DESCRIPTIONS.

 *  SECTION 3: TRAVEL TABLE.  EACH LINE CONTAINS A LOCATION NUMBER (X), A SECOND

 *      LOCATION NUMBER (Y), AND A LIST OF MOTION NUMBERS (SEE SECTION 4).

 *      EACH MOTION REPRESENTS A VERB WHICH WILL GO TO Y IF CURRENTLY AT X.

 *      Y, IN TURN, IS INTERPRETED AS FOLLOWS.  LET M=Y/1000, N=Y MOD 1000.

 *              IF N<=300       IT IS THE LOCATION TO GO TO.

 *              IF 300<N<=500   N-300 IS USED IN A COMPUTED GOTO TO

 *                                      A SECTION OF SPECIAL CODE.

 *              IF N>500        MESSAGE N-500 FROM SECTION 6 IS PRINTED,

 *                                      AND HE STAYS WHEREVER HE IS.

 *      MEANWHILE, M SPECIFIES THE CONDITIONS ON THE MOTION.

 *              IF M=0          IT'S UNCONDITIONAL.

 *              IF 0<M<100      IT IS DONE WITH M% PROBABILITY.

 *              IF M=100        UNCONDITIONAL, BUT FORBIDDEN TO DWARVES.

 *              IF 100<M<=200   HE MUST BE CARRYING OBJECT M-100.

 *              IF 200<M<=300   MUST BE CARRYING OR IN SAME ROOM AS M-200.

 *              IF 300<M<=400   PROP(M MOD 100) MUST *NOT* BE 0.

 *              IF 400<M<=500   PROP(M MOD 100) MUST *NOT* BE 1.

 *              IF 500<M<=600   PROP(M MOD 100) MUST *NOT* BE 2, ETC.

 *      IF THE CONDITION (IF ANY) IS NOT MET, THEN THE NEXT *DIFFERENT*

 *      "DESTINATION" VALUE IS USED (UNLESS IT FAILS TO MEET *ITS* CONDITIONS,

 *      IN WHICH CASE THE NEXT IS FOUND, ETC.).  TYPICALLY, THE NEXT DEST WILL

 *      BE FOR ONE OF THE SAME VERBS, SO THAT ITS ONLY USE IS AS THE ALTERNATE

 *      DESTINATION FOR THOSE VERBS.  FOR INSTANCE:

 *              15      110022  29      31      34      35      23      43

 *              15      14      29

 *      THIS SAYS THAT, FROM LOC 15, ANY OF THE VERBS 29, 31, ETC., WILL TAKE

 *      HIM TO 22 IF HE'S CARRYING OBJECT 10, AND OTHERWISE WILL GO TO 14.

 *              11      303008  49

 *              11      9       50

 *      THIS SAYS THAT, FROM 11, 49 TAKES HIM TO 8 UNLESS PROP(3)=0, IN WHICH

 *      CASE HE GOES TO 9.  VERB 50 TAKES HIM TO 9 REGARDLESS OF PROP(3).

 *  SECTION 4: VOCABULARY.  EACH LINE CONTAINS A NUMBER (N), A TAB, AND A

 *      FIVE-LETTER WORD.  CALL M=N/1000.  IF M=0, THEN THE WORD IS A MOTION

 *      VERB FOR USE IN TRAVELLING (SEE SECTION 3).  ELSE, IF M=1, THE WORD IS

 *      AN OBJECT.  ELSE, IF M=2, THE WORD IS AN ACTION VERB (SUCH AS "CARRY"

 *      OR "ATTACK").  ELSE, IF M=3, THE WORD IS A SPECIAL CASE VERB (SUCH AS

 *      "DIG") AND N MOD 1000 IS AN INDEX INTO SECTION 6.  OBJECTS FROM 50 TO

 *      (CURRENTLY, ANYWAY) 79 ARE CONSIDERED TREASURES (FOR PIRATE, CLOSEOUT).

 *  SECTION 5: OBJECT DESCRIPTIONS.  EACH LINE CONTAINS A NUMBER (N), A TAB,

 *      AND A MESSAGE.  IF N IS FROM 1 TO 100, THE MESSAGE IS THE "INVENTORY"

 *      MESSAGE FOR OBJECT N.  OTHERWISE, N SHOULD BE 000, 100, 200, ETC., AND

 *      THE MESSAGE SHOULD BE THE DESCRIPTION OF THE PRECEDING OBJECT WHEN ITS

 *      PROP VALUE IS N/100.  THE N/100 IS USED ONLY TO DISTINGUISH MULTIPLE

 *      MESSAGES FROM MULTI-LINE MESSAGES; THE PROP INFO ACTUALLY REQUIRES ALL

 *      MESSAGES FOR AN OBJECT TO BE PRESENT AND CONSECUTIVE.  PROPERTIES WHICH

 *      PRODUCE NO MESSAGE SHOULD BE GIVEN THE MESSAGE ">$<".

 *  SECTION 6: ARBITRARY MESSAGES.  SAME FORMAT AS SECTIONS 1, 2, AND 5, EXCEPT

 *      THE NUMBERS BEAR NO RELATION TO ANYTHING (EXCEPT FOR SPECIAL VERBS

 *      IN SECTION 4).

 *  SECTION 7: OBJECT LOCATIONS.  EACH LINE CONTAINS AN OBJECT NUMBER AND ITS

 *      INITIAL LOCATION (ZERO (OR OMITTED) IF NONE).  IF THE OBJECT IS

 *      IMMOVABLE, THE LOCATION IS FOLLOWED BY A "-1".  IF IT HAS TWO LOCATIONS

 *      (E.G. THE GRATE) THE FIRST LOCATION IS FOLLOWED WITH THE SECOND, AND

 *      THE OBJECT IS ASSUMED TO BE IMMOVABLE.

 *  SECTION 8: ACTION DEFAULTS.  EACH LINE CONTAINS AN "ACTION-VERB" NUMBER AND

 *      THE INDEX (IN SECTION 6) OF THE DEFAULT MESSAGE FOR THE VERB.

 *  SECTION 9: LOCATION ATTRIBUTES.  EACH LINE CONTAINS A NUMBER (N) AND UP TO

 *      20 LOCATION NUMBERS.  BIT N (WHERE 0 IS THE UNITS BIT) IS SET IN

 *      COND(LOC) FOR EACH LOC GIVEN.  THE COND BITS CURRENTLY ASSIGNED ARE:

 *              0        LIGHT

 *              1       IF BIT 2 IS ON: ON FOR OIL, OFF FOR WATER

 *              2       LIQUID ASSET, SEE BIT 1

 *              3       PIRATE DOESN'T GO HERE UNLESS FOLLOWING PLAYER

 *              4       CANNOT USE "BACK" TO MOVE AWAY

 *      BITS PAST 10 INDICATE AREAS OF INTEREST TO "HINT" ROUTINES:

 *              11      TRYING TO GET INTO CAVE

 *              12      TRYING TO CATCH BIRD

 *              13      TRYING TO DEAL WITH SNAKE

 *              14      LOST IN MAZE

 *              15      PONDERING DARK ROOM

 *              16      AT WITT'S END

 *              17      CLIFF WITH URN

 *              18      LOST IN FOREST

 *              19      TRYING TO DEAL WITH OGRE

 *              20      FOUND ALL TREASURES EXCEPT JADE

 *      COND(LOC) IS SET TO 2, OVERRIDING ALL OTHER BITS, IF LOC HAS FORCED

 *      MOTION.

 *  SECTION 10: CLASS MESSAGES.  EACH LINE CONTAINS A NUMBER (N), A TAB, AND A

 *      MESSAGE DESCRIBING A CLASSIFICATION OF PLAYER.  THE SCORING SECTION

 *      SELECTS THE APPROPRIATE MESSAGE, WHERE EACH MESSAGE IS CONSIDERED TO

 *      APPLY TO PLAYERS WHOSE SCORES ARE HIGHER THAN THE PREVIOUS N BUT NOT

 *      HIGHER THAN THIS N.  NOTE THAT THESE SCORES PROBABLY CHANGE WITH EVERY

 *      MODIFICATION (AND PARTICULARLY EXPANSION) OF THE PROGRAM.

 *  SECTION 11: HINTS.  EACH LINE CONTAINS A HINT NUMBER (ADD 10 TO GET COND

 *      BIT; SEE SECTION 9), THE NUMBER OF TURNS HE MUST BE AT THE RIGHT LOC(S)

 *      BEFORE TRIGGERING THE HINT, THE POINTS DEDUCTED FOR TAKING THE HINT,

 *      THE MESSAGE NUMBER (SECTION 6) OF THE QUESTION, AND THE MESSAGE NUMBER

 *      OF THE HINT.  THESE VALUES ARE STASHED IN THE "HINTS" ARRAY.  HNTMAX IS

 *      SET TO THE MAX HINT NUMBER (<= HNTSIZ).

 *  SECTION 12: UNUSED IN THIS VERSION.

 *  SECTION 13: SOUNDS AND TEXT.  EACH LINE CONTAINS EITHER 2 OR 3 NUMBERS.  IF

 *      2 (CALL THEM N AND S), N IS A LOCATION AND MESSAGE ABS(S) FROM SECTION

 *      6 IS THE SOUND HEARD THERE.  IF S<0, THE SOUND THERE DROWNS OUT ALL

 *      OTHER NOISES.  IF 3 NUMBERS (CALL THEM N, S, AND T), N IS AN OBJECT

 *      NUMBER AND S+PROP(N) IS THE PROPERTY MESSAGE (FROM SECTION 5) IF HE

 *      LISTENS TO THE OBJECT, AND T+PROP(N) IS THE TEXT IF HE READS IT.  IF

 *      S OR T IS -1, THE OBJECT HAS NO SOUND OR TEXT, RESPECTIVELY.  NEITHER

 *      S NOR T IS ALLOWED TO BE 0.

 *  SECTION 14: TURN THRESHHOLDS.  EACH LINE CONTAINS A NUMBER (N), A TAB, AND

 *      A MESSAGE BERATING THE PLAYER FOR TAKING SO MANY TURNS.  THE MESSAGES

 *      MUST BE IN THE PROPER (ASCENDING) ORDER.  THE MESSAGE GETS PRINTED IF

 *      THE PLAYER EXCEEDS N MOD 100000 TURNS, AT WHICH TIME N/100000 POINTS

 *      GET DEDUCTED FROM HIS SCORE.

 *  SECTION 0: END OF DATABASE. */
