This program is the companion to my papers
"A Texbook case of pentagram rigidity".
and
"pentagram rigidity for centrally symmetric octagons".
Mostly the program is a companion for this second paper.

Compile the program using  the command
javac *.java

Run the program using the command
java Main 

When the program opens up, the first thing you should
do is find the button that says INSTRUCTIONS and
click on it. This brings forth a new window which
has instructions in it.
