1. About P.Fract
   ================================
   P.Fract produces different fractal images. Included in this version
   are 4 "orbit" type fractals: Hopalong, Threeply, Quadruptwo and Chip
   and the Mandelbrot set which is calculated using a recursive algorithm
   that tries to detect areas of the same color and fills them.
   I got the names and formulas of the orbit type fractals from the great
   PC software FRACTINT.

   You can save and load your favourite images and make a slideshow of them.

   Try the slideshow option with the example database: First clear the
   slideshow filter and set the delay to 2 seconds or what ever you like.
   Make shure that the 'Mark area' option is disabled.
   You can stop the slideshow tapping on the screen.
   Then try to set the filter to 'M' (the filter is case sensitive), that
   means only images with names starting with 'M' will be displayed,
   and the delay to 1 sec. Now 'Mark area' should be enabled.

   With the 'Zoom' option you can enlarge an area of the Mandelbrot set.
   It should be possible to produce some kind of Mandelbrot movie if the
   area of the different zoomed images differs not to much and you set
   the slideshow delay to 0.2 or less seconds. But that will drain a lot
   of batteries unless you do not use the Palm emulator

   On color devices such as Palm IIIc pressing the up or down button starts
   color cycling.

   P.Fract requires MathLib which you can obtain at
	http://www.radiks.net/~rhuebner/mathlib.zip

   PalmOS 3.x is required.

2. History
   =======
   26/01/1998 - Released version 1.10 of Fract
   02/02/1998 - Released version 1.12 of Fract
                Added: Detection of correct OS version,
                Selectable backup of database
   17/02/1998 - Completely new version, now called PalmFract starting with
                version 0.9
                Added 4 fractal types Qadruptwo, Threeply, Chip and the
                Mandelbrot set, zoom option, load/save of images, slideshow
   20/05/1998 - Version 0.9a, should work with Palm OS 3
   01/05/1999 - Version 1.0, added scale for orbit fractals, some bug fixes.
   15/09/2000 - Version 2.0
		   Color support for Palm IIIc
		   16 grey levels for greyscale PalmOS 3.5
		   Color cycling on color devices
                Integer math calculation for Mandelbrot
                Simple but resumable calculation method for Mandelbrot 		   
   16/09/2000 - Version 2.01
		   Fixed a problem with aspect ratio correction of Mandelbrot :-(
   24/09/2000 - Version 2.03
