Requirements to create plugin for Cameo Systems Modeler

[ranjitkarsomit@gmail.com]

I want to create a plugin implementing certain algorithm for the "Cameo systems modeler". However, I am quite confused about the requirements. Can I create a plugin in python or only Java is acceptable?
Also, it would be helpful if someone can help me understand framework for plugin implementation in the "Cameo Systems Modeler". Thank you in advance.
