This is the "Do What You Want To Free License", alias "What? Free!", and officially abbreviated "W?F!".
It is intended to be the least restrictive license document. If it is somehow discovered that it still imposes restrictions it will be updated to a new version that does not. The most current version is displayed in full below.
Below is the full text of the latest version:
