INTRODUCTION
	This program was written to aid myself in the creation of other
binary hacking based tools. I found that there were no other tools for
unix that did what some DOS tools (ie. Tile layer and Naga) did. Since I
really don't need editing capabilities right now, I decided I'd keep this
simple for the time being.


WHAT DOES IT DO?
	BnuView can be used to view the graphical data within a binary
file. Right now the supported file types are:

	* bpp1:		1 bit per pixel, 2 color (ie. black/white) graphics.
	* gameboy:	2 bits per pixel, overlayed bytes, 4 color graphics.
	* nes: 		2 bits per pixel, overlayed tiles, 4 color graphics.

	For the time being, the program doesn't load the entire file into
memory, so you should be able to view files as big as your operating
system supports.


INSTALLATION
	First, you are required to have SVGALIB installed on your system,
which most distributions have packaged. After you know you have SVGALIB
installed (since I don't have a configure script), to the following:

	# make
	# make install

	Unless some error came up, it should be installed.


HOW DO I USE IT?

	First, invoke the program like this:

	# bnuview ff1.nes

	(where ff1.nes is the file you want to view)

	The program should come up, and in the top left corner your
tile display "window" should be present. The program supports the use of
two tile dimensions: 8x8, and 8x16. The default is 8x8.

	The controls on the main keyboard are very easy to get used to,
and are as follows:

	z	Down a line
	w	Up a line

	s	Down a byte (useful for aligning graphics)
	a	Up a byte

	x	Down a page
	e	Up a page

	1	Switch to BPP1 viewing
	2	Switch to Gameboy viewing
	3	Switch to NES viewing

	8	Switch to 8x8 tile mode
	9	Switch to 8x16 tile mode
	
	q	Quit, obviously.

	These controls are also printed in the viewer screen, so there is
no reason to memorize them.
