PROGRAMS
--------

	- XBD.EXE, the game,
	- XBDE.EXE, level editor for XBD.EXE,
	- BITMAP.EXE, bitmap editor for XBD.EXE.



INSTALLATION 
------------

	To use these programs you must copied them to your play
	directory. 

	You also need to copied some files to the play directory or
	another one. This later one can be set in the file XBD.H
	with the LIB define, or with the XBDLIB environment variable.
		
	Those files are :
		- xbdlv*, levels for the game,
		- default, default level,
		- bitmaps.dat, all bitmaps used by the game,
		- scores, all scores.

	You find those files in the BITMAPS directory.


	If you want your real name in the score file, you must set
	the USER environment variable. 



COMPILATION
-----------

	The Makefile is writen for GMAKE (GNU make) and use the
	Microsoft C compiler and Assembler. 



XBD.EXE
-------

	Usage : XBD [-l level]

	The goal is to collect the more of diamonds, the exit to next
	level will blink when you will get enough diamond. New level
	gives you one life more. For each level you have a limited
	time, and a limited number of lives.


	Keys used within the game :

		- ARROWS, move the guy,
		- 'R' or 'r', redraw the screen,
		- 'D' or 'd', kill the guy,
		- SPACE, pauses the game,
		- ESC, ends the game.

	
XBDE.EXE
--------

	Usage : XBDE [-h heigth] [-w width] -l level

	With XBDE you can edit the level files for XBD. Those files
	must be in the current directory, or in the directory
	precised by XBDLIB.

	
	Keys used int the editor :

		- ARROWS, move the cursor,
		- PG_UP and PG_DOWN, chose the bitmap,
		- SPACE, set the current position with the current
			 bitmap,
		- 'C' or 'c', clear the level,
		- 'U' or 'u', save the level,
		- ESC, ends editing.

	All available bitmaps are on the right side of the screen.
	The small cursor on their left shows the current selected
	bitmap (change with PG_UP and PG_DOWN), the other one on the
	right side shows the bitmap under the level cursor.



BITMAP.EXE
----------

	Usage : BITMAP

	This program allows you to edit all bitmaps available in the
	BITMAPS.DAT file. This file must be in the current directory,
	and after editing you must copy it in the play directory or
	the one precised by XBDLIB.

	All bitmaps are drawn on the top of the screen, the current
	bitmap is zoomed in the middle, its name is printed and all
	colors are drawn on the rigth of the screen.

	
	Keys used in the editor :

		- ARROWS, move the cursor on the zoomed bitmap,
		- PG_UP and PG_DOWN, chose the current bitmap,
		- SPACE, set the current pixel with the current
			 color,
		- '+' and '-', chose the current color,
		- 'S' or 's', save the bitmaps,
		- ESC, ends editing.

	A small cursor indicates wich bitmap is currently being
	edited. 

	On the left of all colors a square indicates the current
	color, and on the right another square gives the color of the
	current pixel.
