.SH "NAME"
greed \- eat a game field until you run out of moves
.SH "SYNOPSIS"
.HP \w'\fBgreed\fR\ 'u
\fBgreed\fR [\-s]
.SH "DESCRIPTION"
.PP
The object of Greed is to erase as much of the screen as possible by moving around in a grid of numbers\&. To move your cursor, simply use your arrow keys or the the \*(Aqhjklyubn\*(Aq keys or your numeric keypad (with Num Lock on)\&. Your location is signified by the @ symbol\&. The following diagram shows how the basic movemebt keys work\&.
.sp
.if n \{\
.RS 4
.\}
.nf
y k u  7 8 9
 \e|/    \e|/
h\-+\-l  4\-+\-6
 /|\e    /|\e
b j n  1 2 3
.fi
.if n \{\
.RE
.\}
.PP
When you move in a direction, you erase N number of grid squares in that direction, N being the first number in that direction\&. Your score reflects the total number of squares eaten\&.
.PP
Greed will not let you make a move that would have placed you off the grid or over a previously eaten square\&. If no valid moves exist, your game ends\&.
.PP
Other Greed commands are \*(AqCtrl\-L\*(Aq to redraw the screen, \*(Aqp\*(Aq to toggle the highlighting of the possible moves, and \*(Aqq\*(Aq to quit\&.
.PP
The only command line option to Greed is \*(Aq\-s\*(Aq to output the high score file\&.
.SH "ENVIRONMENT"
.PP
The environment variable GREEDOPTS can override the default color set, which will be parsed as a string of the form:
.sp
.if n \{\
.RS 4
.\}
.nf
	<c1><c2><c3><c4><c5><c6><c7><c8><c9>[:[p]]
.fi
.if n \{\
.RE
.\}
.PP
where <cn> is a character decribing the color for digit n\&. The color letters are read as follows:
.sp
.if n \{\
.RS 4
.\}
.nf
	b = blue,
	g = green,
	c = cyan,
	r = red,
	m = magenta,
	y = yellow,
	w = white\&.
.fi
.if n \{\
.RE
.\}
.PP
In addition, capitalizing a letter turns on the A_BOLD attribute for that letter\&.
.PP
If the string ends with a trailing :, letters following are taken as game options\&. At present, only \*(Aqp\*(Aq (equivalent to an initial \*(Aqp\*(Aq command) is defined\&.
.SH "FILES"
.PP
/var/games/greed/greed\&.hs
.RS 4
Default location of Greed high scores\&.
.RE
.PP
~/\&.greedscores
.RS 4
Where they\*(Aqre put if the default location cannot be written to\&.\&.

This really ought to be an X game, but that would have been too much like work\&.
