NetHack 3.4.3 for OpenVMS VAX 7.3 -- kit NETHACK_VAX_343
=======================================================

NetHack 3.4.3 (7-DEC-2003) built, unmodified except for one configuration setting (the
playground directory in vmsconf.h), from the official source with the distribution's own
VMS procedures and DEC C 6.4.  Prepared by Douglas P. Fields, Jr. (symbolics@lisp.engineer).
Licence: NetHack General Public License (LICENSE.TXT).  Provenance: SOURCES.TXT.

Install (as SYSTEM; no privileges are granted to the game, nothing outside the tree changes)
--------------------------------------------------------------------------------------------
  $ SET DEFAULT dir-holding-the-kit-files
  $ @NETHACK_INSTALL                  (installs NETHACK_VAX_343.BCK)
  $ @NETHACK_INSTALL "" REPLACE       (removes the old installation first, keeps scores/saves)
  $ @NETHACK_UNINSTALL [CHECK]        (removes only what the manifest recorded; CHECK = dry run)

What goes where
---------------
  SYS$COMMON:[SYSLIB.NETHACK]         program, data library NH-DATA.DLB, NETHACK.COM, TERMCAP,
                                      RECOVER.EXE, GUIDEBOOK.DOC, NETHACK_SETUP.COM, manifest
  SYS$COMMON:[SYSLIB.NETHACK.SAVE]    saved games

Play (any user, any VT100/VT200-class terminal, including Telnet)
------------------------------------------------------------------
  $ @SYS$COMMON:[SYSLIB.NETHACK]NETHACK_SETUP
  $ NETHACK                           (a new game; S saves and leaves; run NETHACK to restore)
  $ NETHACK "-s"                      (the score list)
  $ RECOVER                           (rebuild a save from the level files of a crashed game)
Quote options; DCL upper-cases an unquoted argument ("-uConan-B" not -uConan-B).  The
distribution's NETHACK.COM turns DECgraphics on for DEC terminals.  Options for every game:
  $ DEFINE NETHACKOPTIONS "noLegacy,!autopickup"
(or a file SYS$LOGIN:NETHACK.INI with lines  OPTIONS=...).  Wizard mode is off: the compiled-in
wizard user NHWIZARD does not exist.

Security of this installation (read it)
---------------------------------------
NetHack is installed WITHOUT privileges and without INSTALL: every player runs the program with
his own rights.  The playground must therefore be writable by every player (world RWE).  What
the installer does to keep players apart:
  * an inheritable ACE  (IDENTIFIER=[*,*],OPTIONS=DEFAULT,ACCESS=NONE)  on the playground and on
    [.SAVE]: every file a player creates (level files, lock file, save file, bones) is private
    to that player (and SYSTEM) -- another user gets a protection violation when trying to read,
    copy, delete, rename, change the protection of, append to, or make a new version of it;
  * the program and data files are owned by SYSTEM, world read/execute only.
What it cannot do without privileges:
  * RECORD, LOGFILE, PERM and PANICLOG are shared by all players and are world read/write (they
    must be, to be appended to).  ANY LOCAL USER CAN THEREFORE EDIT OR DELETE THE SCORE LIST.
    Closing that needs an installed image holding an identifier (INSTALL, CMKRNL, a startup
    entry); this kit does not do that.
  * Bones files are private too, so a dead player's ghost is never met by another player.
  * Anyone can still fill the directory with files of their own (disk quota is the only limit).
