version

type Cmd struct {
	// Check asks which release is newest. It is a FLAG rather than part of
	// the default output because it costs a network round trip, and
	// `version` is printed by scripts, by the installer's own last line,
	// and by anyone diagnosing a mismatch offline — none of which should
	// start depending on GitHub being reachable.
	Check bool `help:"Also ask which release is newest, and say whether this binary is behind. Costs one network call."`
