There are further boolean options that exist in some versions of NetHack
3.2.  (You can learn which options exist in your version by checking your
current option setting, which is reached via the 'O' cmd.)

Boolean option if INSURANCE was set at compile time:
checkpoint save game state after each level change, for possible  [TRUE]
           recovery after program crash

               display effect.  on MSDOS without the termcap
               lib, whether or not to pause for visual effect.    [TRUE]

Any Boolean option can be negated by prefixing it with a '!' or 'no'.


Compound options are written as option_name:option_value.

Compound options which can be set during the game are:

disclose      the types of information you want offered at the end of the
              game  [all]
fruit         the name of a fruit you enjoy eating  [slime mold]
              (basically a whimsy which NetHack uses from time to time).
menustyle     user interface for selection of multiple objects:
              Traditional -- one object at a time prompting;
              Combination -- prompt for classes of interest, then menu;
              Partial     -- skip class prompt, use menu of all objects;
              Full        -- menu for classes of interest, then object menu;
              only the first letter ('T','C','P','F') matters; 'N' (None)
              is a synonym for 'T', as is boolean style negation  [Full]
packorder     a list of default symbols for kinds of objects that gives the
              order in which your pack will be displayed  [")[%?+!=/(*`0_]
              (If you specify only some kinds of items, the others from the
              default order will be appended to the end.)
pickup_types  a list of default symbols for kinds of objects to autopickup
              when that option is on  [all]
scores        the parts of the score list you wish to see when the game ends
              You choose a combination of top scores, scores around the top
              scores, and all of your own scores.  [!own/3 top/2 around]

Compound options which may be set only on startup are:

dungeon         a list of symbols to be used in place of the default ones for
                drawing the dungeon.
                The symbols are subjected to a fair amount of processing, so
                that you can use C-style escapes such as \n or \081 as well as
                indicate control characters by ^x or meta characters by \Mx.
                As usual, \ can force the next character to be taken
                literally.  Since many of the default symbols are overloaded,
                they are given here by name instead of symbol, with some
                added notes:
                stone                               (solid rock, normally ' ')
