We are going to be working
with a program I call PiScript,
which is largely a Python interface to PostScript.
PostScript is itself the programming language used by printers (the machines);
Python is a programming language that was developed a bit more than 15 years ago, and
it has recently become justifiably popular.
I first developed PiScript as drawing tool
around 4 years ago, and it has grown since. I use it myself
almost exclusively to produce graphics in mathematics.
A principal feature of PiScript is how it allows
TEX to be placed in figures.
There is a
home page for PiScript,
which ought to be useful.
You can download the PiScript libraries there in the file
piscript-1.00.tar.gz, which is the current version.
As I have said, you do not have to download your own copy of this yet - the package will be available
on BMS computers in my home directory, and it is this copy
that will incorporate bug fixes I make during the workshop.
