               Instructions for Installing NetHack 3.4.3
                     on a VMS (aka OpenVMS) system
               =========================================

0.  Please read this entire file before trying to build or install
    NetHack, then read it again!

1.  Building NetHack requires a C compiler (either Compaq C, DEC C,
    VAX C, or GNU C) and VMS version V4.6 or later (but see note #9).
    This release has been tested with Compaq C V6.4 on Alpha/VMS V7.3-1
    and with VAX C V3.2 and GNU C 2.7.1 on VAX/VMS V5.5-2.  The build
    procedure (vmsbuild.com) should not need to be modified; it accepts
    an option for selecting the compiler, and it can detect different
    versions which might require specific command qualifiers.  Versions
    of VAXC earlier than V2.3 will produce many warning messages (about
    200 per source file; over to 25,000 total!), but NetHack has been
    verified to compile, link, and execute correctly when built with VAXC
    V2.2 using vmsbuild.com.  There is also a set of Makefiles suitable for
    use with MMS or MMK; they may or may not work with other make utilities.

2.  Make sure all the NetHack files are in the appropriate directory
    structure.  You should set up a directory--referred to as "top" below
    and in some of the assorted files, but which may be a subdirectory--
    that has these subdirectories
        [.dat]          -- data files
        [.doc]          -- documentation files
        [.include]      -- C header files
        [.src]          -- primary source files
        [.sys]          -- parent for [.sys.*]
        [.sys   .share] -- files shared by several ports, including VMS
        [.sys   .vms]   -- VMS-specific source and support files
        [.util]         -- sources for essential utility programs
        [.win]          -- parent for [.win.*]
        [.win   .tty]   -- "window" routines for ordinary terminals
                           (including terminal windows on workstations)
    The following subdirectories may be present, but are not useful for
    building NetHack on VMS and are not required:
        [.sys   .amiga] -- AmigaDOS
        [.sys   .atari] -- Atari TOS
        [.sys   .be]    -- BeBox BeOS
        [.sys   .mac]   -- Macintosh
        [.sys   .msdos] -- MSDOS for IBM PCs and compatibles
        [.sys   .os2]   -- OS/2
        [.sys   .share   .sounds] -- AIFF format audio files
        [.sys   .unix]  -- guess :-)
        [.sys   .wince] -- Windows CE
        [.sys   .wince   .ceinc] -- more WinCE
        [.sys   .wince   .ceinc   .sys] -- ditto
        [.sys   .winnt] -- Windows NT
        [.win   .gem]   -- window routines for Atari/GEM
        [.win   .gnome] -- window routines for Unix/GNOME
        [.win   .Qt]    -- window routines for Qt
        [.win   .share] -- "tile" graphic support
        [.win   .win32] -- Windows NT and Windows CE
        [.win   .X11]   -- window routines for X-Windows; requires X11R4
                           or later and MIT's Athena Widget set
    You must arrange things in this structure or the supplied procedures
    and instructions in this file will not work properly.  Several DCL
    command files are present in the [.sys.vms] subdirectory and won't
    work as intended if they're moved elsewhere.  The file called Files
    in the top directory contains lists of everything that should be in
    each subdirectory, including things that are constructed as NetHack
    is being built.

3.  Prior to beginning compilation, go to the [.include] subdirectory and
    edit vmsconf.h according to its comments.  You should set Local_WIZARD
    and Local_HACKDIR to appropriate values, and you might want to define
    TEXTCOLOR if you have any color VAXstations or color terminals which
    handle ANSI-format escape sequences to set foreground and background
    color for text characters.  (VT241/VT340 color graphics won't work.)
    Other things which may be of interest are SECURE if you intend to
    set up NetHack as an installed image which is granted privileges, and
    SHELL which should be disabled if you intend to allow captive accounts
    to run NetHack.  You may also want to edit file config.h, but that's
    only necessary if you want or need to disable some of the game options.
    The distributed copy of config.h will work successfully on VMS;
    vmsconf.h has conditional code to deal with the UNIX-specific items.

4.  If you have the programming utilities lex or flex and yacc or bison,
    you may edit the procedure [.sys.vms]spec_lev.com and execute it to
    process several source files for NetHack's special level and dungeon
    compilers.  If you don't modify spec_lev.com, it will copy some
    pre-processed versions of the appropriate files (dgn_lex.c, lev_lex.c,
    dgn_yacc.c, lev_yacc.c, dgn_comp.h, and lev_comp.h) from [.sys.share]
    into [.util]*.c and [.include]*.h.
       $ @[.SYS.VMS]SPEC_LEV            ![OPTIONAL]
    If you perform this step, do it prior to executing vmsbuild.com; if
    you don't perform this step, vmsbuild.com will do so for you.

5.  To build NETHACK.EXE and its auxiliary programs, execute the
    following DCL command:
       $ @[.SYS.VMS]VMSBUILD          !defaults to CC, either VAXC or DECC
    or $ @[.SYS.VMS]VMSBUILD "GNUC"   !force "GCC"
    It can take quite a bit of time for a full build to complete.
    vmsbuild.com will display some feedback as it executes; generally
    this will be the name of each source file that's about to be compiled
    or the name of the executable that has just been linked.

6.  If you have already started (or finished) a build and decide to start
    over with a different compiler, you should DELETE [.SRC]CRTL.OPT;*
    first.

7.  After compilation, it's time to perform installation.  Go back to
    the top directory.  Either edit [.sys.vms]install.com to indicate
    where you want everything to be installed, or specify the location
    and "playground" owner on the command line.  Then execute either
       $ @[.SYS.VMS]INSTALL
    or $ @[.SYS.VMS]INSTALL location owner
    where location is a device:[directory] specification and owner is
    either a rights identifier or UIC.  If install.com is not modified
    and if values aren't supplied on the command line, the default values
    used are the translation of logical name HACKDIR, if any, or else
    [.PLAY] (relative to the current directory), and the UIC for the
    current process.  install.com will use the auxiliary programs
    constructed by vmsbuild.com to process quite a few data files in the
    [.dat] subdirectory.  Then it will create the playground directory,
    if necessary, plus the associated [.save] subdirectory.  Next it will
    copy the data files into the playground; this step can take a while.
    Finally it will copy nethack.exe and a few additional support files.

    After it completes, the files [.src]nethack.olb, [.src]nethack.exe,
    [.util]*.obj, [.util]*_comp.exe, and [.util]makedefs.exe can be
    deleted in order to save disk space if desired.  The other program,
    [.util]recover.exe, should not be deleted unless you make a copy of
    it somewhere--perhaps in the playground directory--first.  It can be
    used to resurrect some games disrupted by system or program crash.

8.  The file nethack.com which is copied to the playground directory can
    be used to invoke NetHack, or nethack.exe can be run directly.  Most
    of the command-line options specified in the Unix man-page (file
    [.doc]nethack.txt) are also applicable to VMS.  Some comments at the
    beginning of nethack.com illustrate several of the options.  New
    players should read the file "Guidebook.txt" which will be copied
    into the playground directory as "Guidebook.doc".


Notes:

1.  Save files and bones files from versions 3.4.0, 3.4.1 and 3.4.2 will
    work with 3.4.3; those from earlier versions will not.  The scoreboard
    file (RECORD) from 3.4.x or 3.3.x will also work; one from version
    3.2.x is slightly different format but should be compatible.

2.  To specify user-preference options in your environment, define the
    logical name NETHACKOPTIONS to have the value of a quoted string
    containing a comma separated list of option values.  The option names
    are case-insensitive.
       $ define nethackoptions "noAutoPickup,Dog:Rover,Cat:Felix,DECgraphics"
    One value you'll probably want to specify is "noLegacy" to turn off
    the initial introductory passage.  The "checkpoint" option controls
    whether or not enough data is saved to disk so that the set of level
    files left behind after a crash contains sufficient information for
    recover.exe to be able to construct a save file after the fact.  The
    tradeoff for enabling checkpoint is that using it makes level changes
    do more I/O and take longer.  The "menustyle" option controls some
    aspects of the user interface, and can be set to "menustyle:traditional"
    to make nethack behave more like older versions.

    If logical name or DCL symbol NETHACKOPTIONS is not defined, NetHack
    will try HACKOPTIONS instead.  Regardless of whether or not either
    is defined, it will also try to find a configuration file containing
    additional option settings.  If the value of the translation of
    NETHACKOPTIONS--or HACKOPTIONS--begins with an "@" character then the
    rest of the translation is assumed to be the name of the configuration
    file.  Otherwise, the following are tried:  file specified by logical
    name NETHACKINI, file SYS$LOGIN:NETHACK.INI, and file HOME:NETHACK.CNF
    (note that the C run-time library sets up the value of HOME to match
    sys$login).  Syntax for the configuration file is similar to
    NETHACKOPTIONS, but multiple lines can be used, each must start with
    OPTIONS=, and comments can be included by placing '#' in the first
    column.  Several options which take more complex values (graphics
    representation) can also be present; see the "Guidebook" for details.
    (Guidebook.txt can be found in the [.doc] subdirectory; a copy gets
    placed in the playground directory by install.com.  Also, an example
    configuration file can be found in [.win.X11]nethack.rc.)

3.  Instead of using vmsbuild.com to compile and link everything, you can
    use the set of Makefiles found in the vms subdirectory, provided you
    have an appropriate and compatible make utility.  They've been tested
    using MMK, a freeware clone of Digital's MMS.  There are five of them,
    and the suffix or filetype on their names indicates where they should
    be placed.
       $ copy [.sys.vms]Makefile.top []Makefile.
       $ copy [.sys.vms]Makefile.src [.src]Makefile.
       $ copy [.sys.vms]Makefile.utl [.util]Makefile.
       $ copy [.sys.vms]Makefile.dat [.dat]Makefile.
       $ copy [.sys.vms]Makefile.doc [.doc]Makefile.
    After doing that, edit [.src]Makefile and [.util]Makefile to specify
    pertinent compiler options in CFLAGS, linker options in LFLAGS, and
    libraries in LIBS and/or MORELIBS if the default values aren't right.
    Be sure to make compatible compilation and linking settings in both
    files.  While in there, edit [.util]Makefile to specify the appropriate
    values for lex and yacc, _or_ move to that directory and use MMS or
    make to build targets no_lex and no_yacc which will copy several
    pre-processed files from [.sys.share] into [.util].  Finally, edit
    Makefile in the top directory to specify values for GAMEDIR and
    GAMEOWNER.  This top Makefile invokes [.sys.vms]install.com to do
    much of the actual installation work, so if you want to make any
    customizations or file protection changes, edit install.com to suit.
    Also set MAKE in all of the Makefiles to the appropriate command if
    not using MMS or MMK.

    Once the Makefiles are tailored for your site, give the command
       $ mms all,install
    or $ make all install
    To compile and install everything.  The object files compiled via
    the Makefiles are left as individual .OBJ files rather than placed
    into an object library (in contrast to step #7 above and note #10
    below).  These Makefiles are provided on an as-is basis; vmsbuild.com
    is the preferred way to compile because it's guaranteed to compile
    and link everything.

4.  termcap is an ASCII data file containing descriptions of terminal
    capabilities and the escape sequences that software must use to take
    advantage of them.  If you do not already have a termcap file in use
    on your system there is a small one in file [.SYS.SHARE]TERMCAP.  It
    contains definitions for common Digital terminals, also suitable for
    most clones and emulators.  This file is copied into the playground
    by install.com, and NetHack will use it if it can't find any other
    one.  NetHack uses the following sequence to attempt to locate the
    termcap file:  translation of the logical name TERMCAP (used as-is),
    file NETHACKDIR:TERMCAP, similar file HACKDIR:TERMCAP, GNU-Emacs file
    EMACS_LIBRARY:[ETC]TERMCAP.DAT, file []TERMCAP, and lastly file
    $TERMCAP (which most likely would be a logical name).  If NetHack
    can't find the termcap file, or if the above search sequence finds a
    different one than you'd prefer, then use the DCL ASSIGN or DEFINE
    command to define a value for logical name TERMCAP.

    NetHack also tries fairly hard to figure out what kind of terminal
    you're using.  It checks for logical names (or symbols) NETHACK_TERM,
    HACK_TERM, EMACS_TERM, and lastly TERM.  The last is set up by the
    C run-time library and you cannot use a logical name or symbol for
    it.  If all those fail, or if whichever one succeeds has a value of
    "undefined" or "unknown" (which can happen under VMS V5.4-* and
    V5.5-* for VT420 terminals), NetHack will query the VMS TERMTABLE
    database used by the SMG library routines.  Whatever value NetHack
    eventually comes up with needs to be the name of an entry in the
    termcap file, otherwise a message about "Unknown terminal type" will
    be printed and NetHack will exit.

5.  NetHack contains code which attempts to make it secure in case it's
    installed with privileges (to allow the playground to be protected
    against world write access).  This has only undergone limited testing,
    so install NetHack with privileges at your own risk.  If you discover
    any potential security holes, please let us know so that we can take
    steps to correct the problem(s).  NetHack always includes filename
    punctuation when accessing files, so that it should never be affected
    by inadvertent or malicious logical name definitions, and it always
    deactivates installed privileges prior to spawning a subprocess.

    Note to end users:  "installing with privileges" is an option for
    system managers who set up system-wide access to the game.  Since
    CMKRNL privilege and modification of the system boot routines are
    both required, it is not an option for ordinary users.  There are
    no explicit instructions on how to do such an installation, because
    only system managers who are already familiar with the process and
    its potential security ramifications should even consider it.

    The default setup by install.com assumes no privileges and uses
    world-writable files to allow arbitrary users to play.  This is
    NOT secure and not advisable in any environment where there are
    untrustworthy users, but works fine for many sites.  If you allow
    users to run NetHack from captive accounts (VMS 5.1-* or earlier)
    or from restricted accounts (5.2 and later), you should either make
    sure that they do not have TMPMBX privilege or else disable NetHack's
    ability to spawn an interactive subprocess.  To disable subprocesses,
    disable the "!" (shell escape) command by commenting out the definition
    of SHELL in vmsconf.h prior to building the program.  This necessity
    may be removed in some future release, where NetHack will check for
    captive accounts instead of spawning unconditionally.  Note that
    disabling the SHELL command also prevents spawning MAIL when scrolls
    of new mail are received.

    In order for installed privileges to be used at all, the value of
    HACKDIR (via Local_HACKDIR in vmsconf.h) compiled into the program
    must correspond to the actual playground directory.  If logical name
    HACKDIR (or NETHACKDIR) is used to override that value, installed
    privileges will be deactivated unless its value corresponds to the
    same device and directory as the internal value.  If that internal
    value contains a logical name, only an executive-mode translation
    will be honored; if there is no such translation, installed privs
    will be deactivated.

    To be able to install nethack.exe with privileges (SYSPRV or GRPPRV,
    perhaps EXQUOTA, depending on site usage and needs), you'll need to
    link it with debugging and tracebacks both disabled.  You can do this
    by specifying an argument to vmsbuild.com when performing step #6
    above; pass it "/noTrace/noDebug" as the 4th parameter.
       $ @[.SYS.VMS]VMSBUILD "" "" "" "/noTrace/noDebug"
    /Trace/noDebug is the linker's normal default.  If you've already
    built NetHack, you can relink with tracebacks disabled by doing
       $ @[.SYS.VMS]VMSBUILD "LINK" "" "" "/noTrace/noDebug"

6.  If you can't or won't install nethack.exe with privileges and if you
    don't have access to a privileged account yourself, then if you intend
    to allow other users to access your copy of NetHack you should probably
    place an ACL on the playground directory and its save subdirectory.
    The access control list should contain a default protection ACE which
    grants delete+control access to the playground owner (ie, your own
    account if there's no special games account involved).  install.com
    does not attempt to do this automatically at the present time.  After
    executing install.com to create the playground directory, perform a
    pair of commands similar to the following
       $ SET ACL/ACL=(IDENT=your_id, OPTIONS=DEFAULT, ACCESS=R+W+E+D+C) -
       $_ device:[playground's.parent.directory]playground.DIR
       $ SET ACL/ACL=(IDENT=your_id, OPTIONS=DEFAULT, ACCESS=R+W+E+D+C) -
       $_ device:[playground.directory]SAVE.DIR
    The two commands use the same options, but SET ACL won't accept a
    list of files to modify.  (For recent versions of VMS, SET ACL was
    made obsolete in favor of SET FILE/ACL, which in turn has been made
    obsolete in favor of SET SECURITY/CLASS=FILE/ACL; however, the older
    forms will still work.)  'your_id' should be the rights identifier
    which corresponds to the account which should retain access to those
    files; 'device:[playground's.parent.directory]' is the name of the
    parent directory for the playground (ie, if your playground directory
    is disk$foo:[me.games.nethack.play], then you want to specify
    disk$foo:[me.games.nethack]play.dir on the SET ACL command), and
    'device:[playground.directory]' is the playground itself.  Those ACLs
    establish a default protection scheme such that every newly created
    file in those directories will have an ACL attached to it, and the
    attached ACL will grant 'your_id' full access to the corresponding
    file.  That should allow you to clear away level files from aborted
    games, and to delete old save files if necessary.  It will not enable
    you to run recover.exe on behalf of other users, because you won't be
    able to create files owned by them unless you have elevated privileges.

7.  Many NetHack commands can be aborted by sending it the <escape>
    character when it wants input.  This is displayed as ESC inside the
    game.  Digital VK201 keyboards (used by VT2xx and VT3xx and older
    VAXstations) and VK401 keyboards (used by VT4xx, newer VAXstations,
    and DEC's X Terminals) do not have an <escape> key.  They may
    transmit <escape> for the <F11> key if the terminal or emulator
    window is set to operate in VT100 mode, or there may be a setup-type
    option for making the <` | ~> key behave as <escape>.  If your
    terminal does not have that, or if it's set to a mode where that
    won't work, then just use <ctrl/[> instead.  (Press the "[" key while
    holding down the "Ctrl" key, then release both; <escape> and <ctrl/[>
    have the same ASCII code and are indistinguishable once they reach
    the computer; note that VAXstations and X Terminals _can_ tell the
    difference, but that won't matter for NetHack.)

    VMS NetHack is configured to use the SYS$QIOW system service for
    reading characters from the keyboard.  This allows ^C and ^Y (as well
    as ^X and ^O for wizard mode debugging) to be used as commands without
    being intercepted or interpreted by the terminal driver.  The code
    which parses arrow and function keys is not perfect, and it's possible
    to get strange results if you hold such keys down or just type too
    quickly, particularly on slow multiplexor lines.  Those keys are
    never needed in actual play, and most function keys are just treated
    as <escape> for use in aborting partial commands.

    VMS NetHack also still has code to use SMG$READ_KEYSTROKE instead.
    That can be activated by modifying vmsconf.h and recompiling, but
    it should never be necessary.  If you use it, you'll need to press
    either <esc> or <ctrl/[> twice to abort partial commands, or else
    press an arbitrary function key, such as <PF4>, once.

    If SUSPEND is defined in vmsconf.h, <ctrl/Z> is used for that command.
    Since Unix-style job control is not available, it's used for connecting
    to the parent process if NetHack is running in a subprocess.  When not
    in a subprocess, it doesn't do anything except give a message to the
    effect that it's not doing anything....  The suspend command does not
    save the current game; if you use ^Z to attach to your parent process,
    be sure to remember to eventually reattach to the NetHack subprocess;
    otherwise the game in progress won't get saved when you logout.

8.  NetHack optionally maintains a logfile which receives one line appended
    to it whenever a game ends.  This can be disabled entirely by adding
    an "#undef LOGFILE" directive to vmsconf.h prior to building the
    program, or it can be disabled later by removing the file(s) LOGFILE.;*
    from the playground directory.  If not disabled prior to compilation,
    the logfile can be reinitialized by simply creating an empty file
    named LOGFILE in the playground, but make sure that users are able
    to write into it, or new entries will not be appended.

9.  Some attempt at support for VMS versions earlier than V4.6 has been
    included, but no such obsolete system was available for testing it.
    vmsbuild.com detects the need for the extra support routines and
    arranges automatically for them to be compiled.  The reason that
    special support is needed is that the C Run-Time Library (VAXCRTL)
    underwent a major revision for VMS V4.6 and several routines which
    NetHack utilizes were not available prior to that upgrade.

10. vmsbuild.com collects almost all of the object files (xxx.OBJ) into
    an object library (NETHACK.OLB) as it compiles the source files.
    This should prevent the quota-exceeded problems from the linker
    that some sites have reported for prior versions.  Note that if you
    compile any source files manually, you'll need to replace those
    modules in the object library prior to linking the program:
       $ cc/include=[-.include] [-.sys.vms]vmstty   !for example
       $ libr/obj []nethack vmstty                  !replace VMSTTY
       $ @[-.sys.vms]vmsbuild LINK                  !re-link NETHACK.EXE
    If you forget to replace the library entry, your newly compiled code
    will not be included in the new executable image.

11. To access "wizard mode"--intended for debugging purposes, not to
    spoil the game with unlimited wishes--you must be running from the
    username compiled into the game via Local_WIZARD in vmsconf.h, and
    you must specify "-D" on the command line when invoking NetHack.
    Note that -D must be uppercase, and it must be in quotes to prevent
    the C run-time library's program startup code from converting it into
    lowercase.
       $ @hackdir:nethack "-D"
    Any character name you specify will be ignored in favor of "wizard".

12. At program startup time, NetHack uses the empty file PERM to prevent
    two different processes from using the same character name (under the
    same UIC ownership) at the same time.  It does this by temporarily
    giving that file a second directory entry named PERM.LOCK, then
    removing the alternate entry once started.  If the PERM file is
    missing or inaccessible, NetHack will give a message and then quit.
    Several possible messages and their usual causes are:
       Can't find file perm;1 to lock!
    PERM.;1 is missing from the playground directory.  Fix:  reinstall
    the playground directory using install.com, or use CREATE or an editor
    to make an empty file named PERM.  Version number must be 1.
       Can't lock perm;1 due to directory protection.
    The playground directory is not allowing write access.  Fix:  players
    need to be able to write files for dungeon levels and "bones" into
    the playground directory.  Set the protection or ACL on the xxx.DIR;1
    file in the playground's parent directory to allow write access.
       Can't unlink perm.lock;1.
    The empty file PERM.;1 is protected against delete access; only matters
    under some versions of VMS.  Fix:  set the protection or ACL on PERM.;1
    to allow delete access to players.  Under VMS V5.5-2, delete access is
    not necessary.  PERM does not have to remain writable.
       Waiting for access to perm;1.  (# retries left).
    If some other process is also starting up NetHack at about the same
    time, you may have to wait a short period.  NetHack will retry once
    per second, counting down to 0.  If 0 is reached, the message
       Perhaps there is an old perm.lock;1 around?
    will be displayed and then NetHack will give up.  Fix:  to forcibly
    remove a stale PERM.LOCK entry, issue the following command
       $ SET FILE/REMOVE PERM.LOCK;1
    from the playground directory.  The file PERM should remain intact.
    Do not use that command for real files, only alternate directory
    entries.  If output from a DIRECTORY command on the playground reports
       PERM.LOCK;1          no such file
    then someone has deleted PERM.;1 while the synonym entry was still
    in place, and PERM.LOCK was left as a dangling name which no longer
    points at any file.  The SET FILE/REMOVE command above will fix the
    dangling name; a new PERM.;1 will need to be created as mentioned above.

    In similar fashion, synchronized access to the scoreboard file RECORD
    is accomplished using temporary entry RECORD.LOCK and LOGFILE using
    entry LOGFILE.LOCK.

13. Unless you have both Motif and the Athena Widget set from MIT, you
    will not be able to use the X11 interface on VMS.  Even if you do
    have both those things, such a configuration has not been tested and
    there are no provisions for it in vmsbuild.com.  Makefile.src does
    have the extra source files listed, but not the necessary libraries.

    The X11 port will not compile and link with DECwindows, but it will
    be able to display on a VMS DECwindows X server provided that it and
    its Unix X client have a compatible transport between them (either
    TCP/IP added to VMS or DECnet added to Unix) and session security
    is set up appropriately.  You'll need to add the contents of file
    [.win.X11]NetHack.ad into your DECW$USER_DEFAULTS:DECW$XDEFAULTS.DAT,
    and modify some of the lines.  The DECwindows window manager does not
    support having input focus automatically follow the pointer, so you
    should uncomment the "NetHack*autofocus" resource line.  (For Motif
    this may not be necessary, depending on customization options.)
    Uncommenting the "NetHack*slow" line is highly recommended.  You'll
    also need to set "NetHack*fonts: fixed" (rather than "variable"), and
    either set the map font to "fixed" too or install the "nh10" font
    that comes in file [.win.X11]nh10.bdf.  If NetHack warns that the map
    font is variable, then something isn't set up properly.

    After creating or modifying decw$xdefaults.dat, you must restart the
    window manager in order for any changes to take effect; it's easiest
    to just make the session manager quit and then log in again.

14. If necessary, send problem reports via e-mail to
       <devteam@nethack.org>
    Always include version information for NetHack, the operating system,
    and the C compiler used.
