The breve simulation environment 2.5.1

breve is a free, open-source software package which makes it easy to build 3D simulations of decentralized systems and artificial life.
Users define the behaviors of agents in a 3D world and observe how they interact. breve includes physical simulation and collision detection so you can simulate realistic creatures, and an OpenGL display engine so you can visualize your simulated worlds.
breve simulations are written in an easy to use language called steve. The language is object-oriented and borrows many features from languages such as C, Perl and Objective C, but even users without previous programming experience will find it easy to jump in. More information on the steve language can be found in the documentation section.
breve features an extensible plugin architecture which allows you to write your own plugins and interact with your own code. Writing plugins is simple and allows you to expand breve to work with existing projects. Plugins have been written in breve to generate MIDI music, download web pages, interact with a Lisp environment and interact with the "push" language.
Enhancements:
- An experimental Python language bridge is now available.
- There were also fixes related to Push language support and fixes for broken demos.
