 114 The Go programming language is an open source project to make
 115 programmers more productive.
 116
 117 Go is expressive, concise, clean, and efficient. Its concurrency
 118 mechanisms make it easy to write programs that get the most out of
 119 multicore and networked machines, while its novel type system enables
 120 flexible and modular program construction. Go compiles quickly to
 121 machine code yet has the convenience of garbage collection and the power
 122 of run-time reflection. It's a fast, statically typed, compiled language
 123 that feels like a dynamically typed, interpreted language.
