Introduction

        PosterBrot is a greyscale Mandelbrot set poster generator.  It
will  generate  a  set of PGM image files, which, when printed, can be
combined into a poster.


Features

        -  Portable.   PosterBrot is written in ANSI C, and can ported
to any platform which supports the standard.

        -  FPU support.  Directly uses the MC6888x, if available.

        -  Smooth.  PosterBrot colors by escape radius, rather than by
escape  iteration.   This  method  produces extremely smooth gradients
with fewer iterations per pixel.


System requirements

        - AmigaDOS 2.0
        - Software suitable for printing PGM images
