INTRODUCTION:
	XaoS is a real-time interactive fractal zoomer for DOS, Plan9, X11 and
	SVGAlib. It displays the Mandelbrot set (among other escape
	time fractals) and allows you zoom smoothly into the fractal.
	Various coloring modes are provided for both the points inside and
	outside the selected set. In addition, switching between Julia and
	Mandelbrot fractal types is provided. The first version was a
	poorly written Mandelbrot view by Thomas later modified by Jan to
	support high frame-rate zooming. Other additions were later made
	including autopilot (for those of you without drivers licenses),
	palette changing, GIF saving, and fractal inversion.

WHATS NEW:
	This is mainly bugfix release but some of new features were added too:
	o New recalulating with non rectangular pixels. (for full screen modes)
	  great for modes X :)
	o New palettes with white background
	o Added coprocesor configuration into MS-DOS port - some coloring
	  modes are MUCH faster because of no more SIGFPE ignoring..
	o Added support for 1280x1024 and 1600x1200 into MS-DOS port
	o Default type changed back to double because long double is
	  non standard
	o 9x15 font changed to more compatible and better looking fixed.
	o First release of plan9 port (very interesting OS see
	    http://plan9.att.com..trial version if free)-not 
	    complette yet..colors looks ugly and keys like 
	    arrows does not work.. 

	    someone who can help me?

	o Added key defines for old svgalib compatibility.


REQUIREMENTS:
	XaoS, by default, uses floating point math for its calculations.
	This may be slow on some computers. The program was developed on a
	Pentium running at 100 MHz, so we can't guaranty that it will run 
	well on any slower system. If you just want to catch a cursory
	glance at XaoS' capabilities on faster systems then you might try
	compiling it for fixed point arithmetic by editing config.h
	accordingly.

	To compile XaoS, DOS, Plan9 or UNIX and X11 (or SVGAlib for Linux) is
	required. We are discussing the possibility of porting it to OS/2.
	Your C compiler must be ANSI compliant. GNU CC is highly
	recommended. An 8-bit display is required at this point since we
	haven't coded for TrueColor displays yet.

FTP:
	XaoS comes in various files:
	  XaoS-1.2.tar.gz	sources
	  XaoS*.rpm		Redhat packages
	  			Debian packages is coming soon
	  xaos12b.zip		MS-DOS binaries
	  xaos12s.zip		MS-DOS sources(unix one works too..just for those
	  			w/o tar and gzip)
	All files are placed at:
	  ftp.ta.jcu.cz/pub/linux/hubicka
	UNIX releated:
	  sunsite.unc.edu/pub/Linux/Incoming...will be moved
	  tsx-11.mit.edu
	  ftp.x.org/contrib/graphics
	Redhat package:
	  ftp.redhat.com/pub/contrib/...
	DOS version:
	  ftp.simtel.net/pub/simtelnet/msdos/graphics
HOMEPAGE:
	Europe:	http://www.paru.cas.cz/~hubicka/XaoS/
	U.S.:	http://www.realtime.net/~amadeus/XaoS/	(it is omposible to update it
							 now. Pleause use European one)

INSTALL:
	Installation methods are described in the file "INSTALL".

USAGE:
	XaoS has no command line options as of yet. It is one entirely
	self contained executable. Runtime help is provided by typing "H".
