The standard tty display and command structure resem-       ble rogue.   A      Other, more graphical display options exist if you are using &      either a PC, or an X11 interface.  A      To get started you really only need to  know  two  commands. A      The command ? will give you a list of the available commands A      (as well as other information) and the command / will  iden- +      tify the things you see on the screen.      AUTHORS A      Jay Fenlason (+ Kenny Woodland, Mike Thome  and  Jon  Payne) A      wrote  the  original hack, very much like rogue (but full of       bugs).   A      Andries Brouwer continuously deformed their sources into  an       entirely different game.   A      Mike Stephenson has continued  the  perversion  of  sources, A      adding  various  warped character classes and sadistic traps A      with the help of many strange  people  who  reside  in  that A      place  between  the  worlds,  the  Usenet Zone.  A number of A      these miscreants are immortalized in the historical roll  of '      dishonor and various other places.   A      The resulting mess is now  called  NetHack,  to  denote  its A      development  by  the  Usenet.  Andries Brouwer has made this A      request for the distinction, as he may eventually release  a       new version of his own.   FILES A      All    files    are    in    the    playground,     normally A      /usr/games/lib/nethackdir.   If  DLB  was defined during the A      compile, the data files and special levels will be inside  a A      larger  file,  normally  nhdat,  instead  of  being separate       files. 4      nethack                     The program itself.<      data, oracles, rumors       Data files used by NetHack.1      options, quest.dat          More data files. 1      help, hh                    Help data files. 6      cmdhelp, opthelp, wizhelp   More help data files.;      *.lev                       Predefined special levels. A      dungeon                     Control file for special levels. <      history                     A short history of NetHack.@      license                     Rules governing redistribution.9      record                      The list of top scorers. :      logfile                     An extended list of games(                                  played.@      xlock.nnn                   Description of a dungeon level.8      perm                        Lock file for xlock.dd.>      bonesDD.nn                  Descriptions of the ghost and9                                  belongings of a deceased ,                                  adventurer.>      save                        A subdirectory containing the-                                  saved games.    ENVIRONMENT *      USER or LOGNAME      Your login name..      HOME                 Your home directory.%      SHELL                Your shell. 4      TERM                 The type of your terminal.8      HACKPAGER or PAGER   Replacement for default pager.'      MAIL                 Mailbox file. 8      MAILREADER           Replacement for default reader@                           (probably /bin/mail or /usr/ucb/mail).%      NETHACKDIR           Playground. <      NETHACKOPTIONS       String predefining several NetHack"                           options.  >      In addition, SHOPTYPE is used in debugging (wizard) mode.   SEE ALSO)      dgn_comp(6), lev_comp(6), recover(6)    BUGS      Probably infinite.       2      Dungeons & Dragons is a Trademark of TSR Inc.
