Create a project.clj that looks something like this:
(defproject your-project-name "your.project.version":description"A description of your project":dependencies [[org.clojure/clojure "1.2.0"]
Using Penumbra directly
Clone the project, then run lein deps followed by lein compile.
To run all example programs one by one, enter this at the REPL:
> (require 'examples)
Depending on your hardware and drivers, some examples may not work properly. If this is the case, please file a report with your hardware, driver version, and the output of glxinfo at the command line.
