If you like, you can bind the flag to a variable using the Var() functions.

	var flagvar int
	func init() {
		flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
	}

Or you can create custom flags that satisfy the Value interface (with
pointer receivers) and couple them to flag parsing by

	flag.Var(&flagVal, "name", "help message for flagname")

		cfg       interface{}
		flagValue interface{}
		expected  interface{}
	}{
		{
			name:      "string: config is overridden by the flag",
			flag:      "foo",
			cfg:       "foo_cfg",
			flagValue: "foo_flag",
			expected:  "foo_flag",
		},
		{
			name:      "bool: config is overridden by the flag",
			flag:      "bar",
			cfg:       true,
			flagValue: false,
			expected:  false,
		},
