CreativeCommonsPresentation is a project mainly written in RUBY and SHELL, it's free.
Creative Commons Presentation and Basic Usage Management Test Suite
This repository contains a presentation on Creative Commons I did for my grad school research group. It contains an overview of how Creative Commons works and an example of programatic control of CC-licensed entities. The programatic control is implemented in Ruby and contains a test suite that can be used to show that it's implemented correctly.
The presentation is in Beamer/LaTeX. To build, given a machine setup to typeset this sort of thing, just type "make" in the current directory.
Code is in the code/ directory
