'''Sprint:''' A sprint is a gathering of people involved in a specific project to further the focused development of some aspect of the project, such as working on sections of code, writing manuals or books, etc. These are effective at getting a lot done quickly for code and manuals (less so for other forms of writing), but can be exhausting and emotionally demanding - make sure you keep food and drink coming!
