Bush league is a general term used to describe an action or thing as being amateur, inferior or crude. In a literal sense, it refers to a low quality minor-league in baseball not associated with any of the major league teams. The term originated from the state of minor-league fields that often were ringed with shrubs and bushes.

# How Akka maps to EAI Patterns

Might be up for debate or just plain wrong. Just some notes I scribbled down some time ago.
