This is heck, a rogue-family game.

The object of the game is to find the Crown of Yendor, somewhere in the
dungeon, and escape the dungeon with it.

The display cursor represents your location.  If you are visible, there
will also be an @ displayed.

To move, use the usual rogue-family direction keys:

	y k u		If the key is shifted (Y, K, etc), the motion
	 \|/		command will be repeated until you run into
	h-@-l		something.  If it is typed with control down
	 /|\		(^Y, ^K, etc), it will be repeated until your
	b j n		immediate environment changes.

Any command can be given a numeric prefix, by typing digits before it.
While typing digits, ^G will abort entering the prefix and DEL or
backspace will remove the last digit.  Commands that don't use the
prefix will ignore it, though.  At this writing, the commands that use
it are the movement commands, . (wait), and s (search).  Commands that
use it treat it as a repetition count.

Besides movement, the commands you can use are:

?	Show this help.

/	Lets you type a character and tells you what that character
	represents in the dungeon display.

^P	Show the last bottom-line message.  Further ^P commands step
	back through older messages, with ^N returning to newer
	messages.  Typing ESC, RETURN, or ^G aborts the message display
	and does nothing else; typing some other command ends the
	message display and then performs that command.

)	Show what weapon you're wielding, if any.

#	Begin an extended command (see below).

<	If you're at the bottom end of a staircase, goes up it; if not,
	does nothing.

>	If you're at the top end of a staircase, goes down it; if not,
	does nothing.

=	Show what rings you're wearing, if any.

[	Show what armour you're wearing, if any.

\	Show what potions, scrolls, rings, and wands you know.  If you
|	use |, the descriptions are shown too; if \, just the effects.

D	(Followed by a direction key.)  Opens a closed door next to
	you, or closes an open one.  The direction key indicates which
	cell the door you want to use is on.

I	Look at only part of your inventory, filtered by object type.
	Object types are indicated using the characters used to display
	them, except that `u' and `k' can be used to indicate unknown
	or known objects, respectively.  You can give multiple
	characters; all objects matching any of them are displayed.

M	Record all the locations you can see on your map.  (The
	operation is aborted if there is, or if there comes to be, a
	monster next to you.)

O	Examine or set options.  (This currently does nothing, since
	there currently are no options implemented.)

P	Put on a ring.

Q	Quit the game.  (This prompts for confirmation.)

R	Remove a ring.

S	Save the game.  (Doesn't really work yet.)

T	Take off whatever armour you're wearing.

W	Wear a suit of armour.

d	Drop an object.

i	See your inventory.

m	(Followed by a direction key.)  Moves in a direction, like the
	movement key, but does not automatically pick up anything in
	the new location.

p	Interactively pick up anything in the same location as you.

q	Quaff a potion.

r	Read a scroll.

w	Wield a weapon.  (To fight empty-handed, type a -, as the
	prompt indicates.)

z	Zap a wand.  Which wand, and the direction you want to zap it
	in, are prompted for.

.	Do nothing for a turn.

s	Search the location you're on, and the eight adjacent
	locations, for secrets.

The # command introduces an extended command, which is a command
represented as a string of text rather than a single character.  When
typing an extended command, you can type ? to be shown the alternatives
available at the point you're at.  Some extended commands have
subcommands (for example, "map" has subcommands "use", "view", and
"auto"); these are indicated by continuing to read input with a space
after the higher-layer command.  For example, if you type #m then the
only matching command is "map", so if you type a space at that point
the game will fill out "#map " and wait for you to type a subcommand.
At any point, ESC will abort the extended command.

At this writing, the extended commands are:

map use
	Lets you use a particular map.  The only common use case for
	this is switching to an appropriate map after teleporting.

map view
	Lets you look at maps in your inventory without switching which
	map you're using.

map auto on
map auto off
	Turns auto-mapping on or off.  It starts out off.  When on, you
	automatically do the equivalent of an M command every time you
	have an opportunity to do anything; only when the M command
	finishes will you actually get control.  (This is convenient
	but, because M takes time, hazardous.)

drop	Allows you to drop multiple things as a single oepration.

seed	Shows the random-number seed used for the game you're playing.
	This can be used with -seed on the command line to get the same
	dungeon again.

quit	Quits the game, like the Q command.  Like the Q command, it
	prompts for confirmation.

inv pack
	Re-assigns inventory letters so inventory-letter order is the
	same as the order things are displayed in when you type i.
