JULIA SETS OF POLYNOMIALS AND RATIONAL MAPS

	Version 2.9  11/2008

Type "cd src; make" to install.

This directory contains several programs for
writing raster files of dynamical images.
The main programs all write postscript output,
in either color or black and white.
The .ps output is piped through "ps2pdf" to obtain .gif
files.  The postscript can be used directly for inclusion in TeX.

If you do not have ps2pdf, a version is provided in bin/ps2pdf.
You may wish to install xv and netpbm.  This can be done
with MacPorts:
	sudo port install xv
	sudo port install netpbm

Each program comes with a directory
containing .run files that exercise it.
To see a list of options for a given program,
type (e.g.) quadps -help.
