A free and open-source Unix-like operating system inspired by a certain Uncyclopedia article.
The operating system is developed by JJPMaster and forked from napalmtorch's PurpleMoon OS, whose source code can be found here.
A few people who I think helped make this project possible include Cassie from Uncyclopedia (who by merely disclosing that she uses GNU/Linux convinced me to create my own OS), and David Gerard, who helped create the Uncyclopedia article that inspired this project, Command Line.
It's written in C# using the Cosmos library.
