INTRODUCTION:
XaoS is a fast portable real-time interactive fractal zoomer. 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 and displaying planes 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.
SUPPORTED PLATFORMS(for now)
UNIXES:
X11 (8bpp pseudocolor 8,15,16,24,31 truecolor, StaticGray and
StaticColor only)
Curses (yes! text mode version available!)

REQUIREMENTS:
XaoS uses floating point math for its calculations. This may be slow on
some computers. The program was developed on a Pentium running at 120 MHz,
but it can work quite well (20fps) on 486Dx/2. I also received nice
letters from users using XaoS at 386/40 or so. Coprocessor is _REALLY_
required. Faster computer is better so alpha/600MHZ recomended.
To compile XaoS you need ANSI compliant compiler with _GOOD_
optimizations. UNIX version uses configure script. Other platforms uses
different ways. GNU CC is highly recommended. Graphics drivers usually
have some additional requirements. (for example xlib for X11, djgpp and
allegro for dos port) Also fast malloc/free routines are recommended
because they are called quite often (10 times per frame)
