;; According to https://golang.org/doc/install/gccgo, gccgo-4.8.2 includes a
;; complete go-1.1.2 implementation, gccgo-4.9 includes a complete go-1.2
;; implementation, and gccgo-5 a complete implementation of go-1.4. Ultimately
;; we hope to build go-1.5+ with a bootstrap process using gccgo-5. As of
;; go-1.5, go cannot be bootstrapped without go-1.4, so we need to use go-1.4 or
;; gccgo-5. Mips is not officially supported, but it should work if it is

"The @code{flags} package provides a command line option parser. The
functionality is similar to the go builtin @code{flag} package, but
@code{flags} provides more options and uses reflection to provide a succinct
way of specifying command line options.")
