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

Path to a working Go tree (>= Go 1.4), with bin, pkg, and src
subdirectories and the Go compiler at bin/go.
If specified, the existing Go installation will be used to
compile host (buildroot) Go.
Leave blank to compile the default bootstrap Go.
