+/* 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 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 game.prop(M % 100) must *not* be 0.
+ * If 400<M<=500 game.prop(M % 100) must *not* be 1.
+ * If 500<M<=600 game.prop(M % 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 game.prop(3)=0, in which
+ * case he goes to 9. Verb 50 takes him to 9 regardless of game.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 % 1000 is an index into section 6. Objects from 50 to
+ * (currently, anyway) 79 are considered treasures (for pirate, closeout).
+ * Section 0: End of database.
+ *
+ * Other sections are obsolete and ignored */
