O is a esoteric programming language used for CodeGolf. It was inspired by languages such as GolfScript, Pyth, K, and ><>, but it has grown into its own language with many cool features. The current interpreter is written in C. You can find the old Java interpreter on the java-interpreter branch.

All documentation for the language is on ReadTheDocs. You can try the language out online at Heroku.
