-- Original README file --------------------------------------------------------

This is export hack, my first semester programming project.

To set it up for your system, you will have to do the following:
	1: create a hack uid, to own the top ten list, etc.
	2: create a hack directory "/usr/lib/game/hack" is the default.
	2.5: make the directory 700 mode.	/* sav files go in there...*/
	3: modify hack.main.c to use the new directory.
	4: modify hack.main.c so it uses the new hack gid.  Gid accounts can
go into magic mode without the password, can get cores with ^G, etc.
(make sure gid isn't checked anywhere else...)
	5: recompile hack.
	6: put it in games after making it set-uid hack.
	8: fix the bugs I undobtedly left in it.
	9: tell me what you think of it.

	Hack uses the UCB file /etc/termcap to get your terminal escape codes.
If you don't use it, you will have to make extensive changes to hack.pri.c

If you find any bugs (That you think I don't know about), or have any
awesome new changes (Like a better save (One that works!)), or have ANY
questions, write me
		Jay Fenlason
		29 East St.
		Sudbury Mass.

or call me at (617) 443-5036.  Since I have both a modem and a teen-age
sister, Good Luck.


Hack is split (roughly) into several source files that do different things.
I have tried to fit all the procedures having to do with a certain segment
of the game into a single file, but the job is not the best in the world.
The rough splits are:

hack.c		General random stuff and things I never got around to moving.
hack.main.c	main() and other random procedures, also the lock file stuff.
hack.mon.c	Monsters, moving, attacking, etc.
hack.do.c	drink, eat, read, wield, save, etc.
hack.do1.c	zap, wear, remove, etc...
hack.pri.c	stuff having to do with the screen, most of the terminal
		independant stuff is in here.
hack.lev.c	temp files and calling of mklev.

Because of the peculiar restraints on our system, I make mklev (create
a level) a separate procedure execd by hack when needed.  The source for
mklev is (Naturaly) mklev.c.  You may want to put mklev back into hack.
Good luck.

Most of hack was written by me, with help from
		Kenny Woodland (KW)	(general random things including
			the original BUZZ())
		Mike Thome	(MT)	(The original chamelian)
	and	Jon Payne	(JP)	(The original lock file kludge and
			the massive CURS())

This entire program would not have been possible without the SFSU Logo
Workshop.  I am eternally grateful to all of our students (Especially K.L.),
without whom I would never have seen Rogue.  I am especially grateful to
Mike Clancy, without whose generous help I would never have gotten to play
ROGUE.

-- Hack 1.0.x README file ------------------------------------------------------

Hack is a display oriented dungeons & dragons - like game.
Both display and command structure resemble rogue.
(For a game with the same structure but entirely different display -
a real cave instead of dull rectangles - try Quest)

Hack was originally written by Jay Fenlason (at lincolnsudbury:
 29 East St., Sudbury Mass., 01776) with help from
 Kenny Woodland, Mike Thome and Jon Payne.
Basically it was an implementation of Rogue, however, with 52+ instead of 26
 monster types.
The current version is more than thrice as large (with such new features as
 the dog, the long worms, the shops, etc.) and almost entirely rewritten
 (only the display routines are the original ones - I must rewrite these
 too one day; especially when you are blind strange things still happen).

Files for hack:
	hack		The actual game
	record		Top 100 list (just start with an empty file)
	news		Tells about recent changes in hack, or bugs found ...
			(Just start with no news file.)
	data		Auxiliary file used by hack to give you the names
			and sometimes some more information on the
			objects and monsters.
	help		Introductory information (no doubt outdated).
	hh		Compactified version of help.
	perm		An empty file used for locking purposes.
	rumors		Texts for fortune cookies.
			(Some of these contain information on the game,
			others are just plain stupid. Additional rumors
			are appreciated.)
	hack.sh		A shell script.
			(We have hack.sh in /usr/games/hack and
			hack in /usr/games/lib/hackdir/hack and all the other
			hack stuff in /usr/games/lib/hackdir - perhaps this
			will make the script clear.
			There is no need for you to use it.)
	READ_ME		This file.
	Original_READ_ME Jay Fenlason's READ_ME

System files used:
	/etc/termcap	Used in conjunction with the environment variable
			$TERM.
	/bin/cat
	/usr/ucb/more
	/bin/sh		Used when $SHELL is undefined.

How to install hack:
0. Compile the sources. Perhaps you should first look at the file config.h
   and define BSD if you are on a BSDtype system,
   define STUPID if your C-compiler chokes on complicated expressions.
   Make sure schar and uchar represent signed and unsigned types.
   If your C compiler doesnt allow initialization of bit fields
   change Bitfield. When config.h looks reasonable, say 'make'.
   (Perhaps you have to change TERMLIB in the makefile.)
1. If it didnt exist already, introduce a loginname `play' .
2. The program  hack  resides in a directory so that it is executable
   for everybody and is suid play:
	---s--s--x  1 play	206848 Apr  3 00:17 hack
   Perhaps you wish to restrict playing to certain hours, or have games
   running under nice; in that case you might write a program play.c
   such that the program play is suid play and executable for everybody
   while all the games in /usr/games are readable or executable for
   play only; all the program play does is asking for the name of a game,
   checking that time-of-day and system load do not forbid playing,
   and then executing the game. Thus:
	-r-sr-sr-x  1 play	 13312 May 24 12:52 play
	---x------  1 play	206848 Apr  3 00:17 hack
   If you are worried about security you might let play do
   chroot("/usr/games") so that no player can get access to the rest
   of the system via shell escapes and the likes.
   If you #define SECURE in config.h then hack will not setuid(getuid())
   before executing a chdir(). Hack will always do setuid(getuid()) with
   a fork. If you do not define UNIX then hack will not fork.
3. The rest of the stuff belonging to hack sits in a subdirectory hackdir
   (on our system /usr/games/lib/hackdir) with modes
	drwx------  3 play	1024 Aug  9 09:03 hackdir
   Here all the temporary files will be created (with names like xlock.17
   or user.5).
4. If you are not really short on file space, creating a subdirectory
   hackdir/save (modes again drwx------) will enable users to save their
   unfinished games.

The program hack is called
$ hack [-d hackdir] [maxnrofplayers]
(for playing) or
$ hack [-d hackdir] -s [listofusers | limit | all]
(for seeing part of the scorelist).
The shell file hack (in this kit called hack.sh) takes care of
calling hack with the right arguments.

-- PC Hack 3.51 README file ----------------------------------------------------

	Welcome to the sources for PC HACK (version 3.51).

Introduction
------------
This is a version of the public domain program HACK 1.03 (copyright
Stichting Mathematisch Centrum, Amsterdam, 1984, 1985.) implemented
under MSDOS with the Microsoft(tm) C v3.0 compiler.

You may copy this version of PC HACK and make any changes you want to
it.  You may give it away, but you may not sell it.


The sources are in ARC format in HACK351S.ARC.  The commands:

	C> arc51 e hack351s makefile make.*
	C> arc51 e hack351s *.h
	C> arc51 e hack351s *.c

will unpack the files.

With a hard disk system, you should be able to type `make' and the sources
will start to be compiled.  This takes a long time.  A floppy disk system
does not really have enough storage.


Compiling
---------
The LARGE compiler model is used.  To add WIZARD mode, add a -DWIZARD
to the MAKEFILE, or a #define WIZARD to the CONFIG.H file.

The MAKEFILE included with PC HACK 3.51 sources is for my version of MAKE.
It is very similar to UNIX(tm) `make'.  See MAKE.DOC for details.

To compile the sources by hand the command for each `filename.c' file is:
	msc -AL -DREGBUG -DLINT_ARGS -Ot -Gs filename.c;


Linking
-------
I used the Microsoft 8086 Linker version 3.01

To link the *.obj files by hand, the command is:
	link @linkfile

Where the contents of the linkfile (not supplied) should be:

decl.obj apply.obj bones.obj cmd.obj do.obj +
do_name.obj do_wear.obj dog.obj eat.obj +
end.obj engrave.obj fight.obj hack.obj +
invent.obj ioctl.obj lev.obj main.obj +
makemon.obj mhitu.obj mklev.obj mkmaze.obj +
mkobj.obj mkshop.obj mon.obj monst.obj +
o_init.obj objnam.obj options.obj pager.obj +
potion.obj pri.obj read.obj rip.obj +
rumors.obj save.obj search.obj shk.obj +
shknam.obj steal.obj termcap.obj +
timeout.obj topl.obj track.obj trap.obj +
tty.obj unix.obj u_init.obj vault.obj +
wield.obj wizard.obj worm.obj worn.obj +
zap.obj version.obj rnd.obj alloc.obj +
msdos.obj 
hack /NOIG /STACK:4000; 


Differences from UNIX HACK
--------------------------
Changes that were introduced to port UNIX HACK to the MSDOS environment
are surrounded with `#ifdef MSDOS', `#endif' directives.

Other changes I have made are surrounded by `#ifdef DGK', `#endif'
directives.  It should be possible to compile these sources without
any of my changes by removing the `#define DGK' line from CONFIG.H.

Also, functions I have added are mainly restricted to the file msdos.c,
although some of them are in other places (ie. wizard.c)
