Cheeky title, but they’re talking about cheat, which is different than man and info in that it’s entirely example based and community maintained.

The cheat system cuts to the chase. You don’t have to piece together clues about how to use a command. You just follow the examples. Of course, for complex commands, it’s not a shortcut for a thorough study of the actual documentation, but for quick reference, it’s as fast as it gets.
