-go-flags: a go library for parsing command line arguments
-=========================================================
-
-This library provides similar functionality to the builtin flag library of
-go, but provides much more functionality and nicer formatting. From the
-documentation:
-
-Package flags provides an extensive command line option parser.
-The flags package is similar in functionality to the go builtin flag package
-but provides more options and uses reflection to provide a convenient and
-succinct way of specifying command line options.
-
-Supported features:
-* Options with short names (-v)
-* Options with long names (--verbose)
-* Options with and without arguments (bool v.s. other type)
-* Options with optional arguments and default values
-* Multiple option groups each containing a set of options
-* Generate and print well-formatted help message
-* Passing remaining command line arguments after -- (optional)
-* Ignoring unknown command line options (optional)
-* Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
-* Supports multiple short options -aux
-* Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
-* Supports same option multiple times (can store in slice or last option counts)
-* Supports maps
-* Supports function callbacks
-
-The flags package uses structs, reflection and struct field tags
-to allow users to specify command line options. This results in very simple
-and consise specification of your application options. For example:
-
-    type Options struct {
-        Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
-    }
-
-This specifies one option with a short name -v and a long name --verbose.
-When either -v or --verbose is found on the command line, a 'true' value
-will be appended to the Verbose field. e.g. when specifying -vvv, the
-resulting value of Verbose will be {[true, true, true]}.
-
-Example:
---------
-	var opts struct {
-		// Slice of bool will append 'true' each time the option
-		// is encountered (can be set multiple times, like -vvv)
-		Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
-
-		// Example of automatic marshalling to desired type (uint)
-		Offset uint `long:"offset" description:"Offset"`
-
-		// Example of a callback, called each time the option is found.
-		Call func(string) `short:"c" description:"Call phone number"`
-
-		// Example of a required flag
-		Name string `short:"n" long:"name" description:"A name" required:"true"`
-
-		// Example of a value name
-		File string `short:"f" long:"file" description:"A file" value-name:"FILE"`
-
-		// Example of a pointer
-		Ptr *int `short:"p" description:"A pointer to an integer"`
-
-		// Example of a slice of strings
-		StringSlice []string `short:"s" description:"A slice of strings"`
-
-		// Example of a slice of pointers
-		PtrSlice []*string `long:"ptrslice" description:"A slice of pointers to string"`
-
-		// Example of a map
-		IntMap map[string]int `long:"intmap" description:"A map from string to int"`
-	}
-
-	// Callback which will invoke callto:<argument> to call a number.
-	// Note that this works just on OS X (and probably only with
-	// Skype) but it shows the idea.
-	opts.Call = func(num string) {
-		cmd := exec.Command("open", "callto:"+num)
-		cmd.Start()
-		cmd.Process.Release()
-	}
-
-	// Make some fake arguments to parse.
-	args := []string{
-		"-vv",
-		"--offset=5",
-		"-n", "Me",
-		"-p", "3",
-		"-s", "hello",
-		"-s", "world",
-		"--ptrslice", "hello",
-		"--ptrslice", "world",
-		"--intmap", "a:1",
-		"--intmap", "b:5",
-		"arg1",
-		"arg2",
-		"arg3",
-	}
-
-	// Parse flags from `args'. Note that here we use flags.ParseArgs for
-	// the sake of making a working example. Normally, you would simply use
-	// flags.Parse(&opts) which uses os.Args
-	args, err := flags.ParseArgs(&opts, args)
-
-	if err != nil {
-		panic(err)
-		os.Exit(1)
-	}
-
-	fmt.Printf("Verbosity: %v\n", opts.Verbose)
-	fmt.Printf("Offset: %d\n", opts.Offset)
-	fmt.Printf("Name: %s\n", opts.Name)
-	fmt.Printf("Ptr: %d\n", *opts.Ptr)
-	fmt.Printf("StringSlice: %v\n", opts.StringSlice)
-	fmt.Printf("PtrSlice: [%v %v]\n", *opts.PtrSlice[0], *opts.PtrSlice[1])
-	fmt.Printf("IntMap: [a:%v b:%v]\n", opts.IntMap["a"], opts.IntMap["b"])
-	fmt.Printf("Remaining args: %s\n", strings.Join(args, " "))
-
-	// Output: Verbosity: [true true]
-	// Offset: 5
-	// Name: Me
-	// Ptr: 3
-	// StringSlice: [hello world]
-	// PtrSlice: [hello world]
-	// IntMap: [a:1 b:5]
-	// Remaining args: arg1 arg2 arg3

-// Package flags provides an extensive command line option parser.
-// The flags package is similar in functionality to the go builtin flag package
-// but provides more options and uses reflection to provide a convenient and
-// succinct way of specifying command line options.
-//
-// Supported features:
-//     Options with short names (-v)
-//     Options with long names (--verbose)
-//     Options with and without arguments (bool v.s. other type)
-//     Options with optional arguments and default values
-//     Multiple option groups each containing a set of options
-//     Generate and print well-formatted help message
-//     Passing remaining command line arguments after -- (optional)
-//     Ignoring unknown command line options (optional)
-//     Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
-//     Supports multiple short options -aux
-//     Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
-//     Supports same option multiple times (can store in slice or last option counts)
-//     Supports maps
-//     Supports function callbacks
-//
-// Additional features specific to Windows:
-//     Options with short names (/v)
-//     Options with long names (/verbose)
-//     Windows-style options with arguments use a colon as the delimiter
-//     Modify generated help message with Windows-style / options
-//
-// The flags package uses structs, reflection and struct field tags
-// to allow users to specify command line options. This results in very simple
-// and consise specification of your application options. For example:
-//
-//     type Options struct {
-//         Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
-//     }
-//
-// This specifies one option with a short name -v and a long name --verbose.
-// When either -v or --verbose is found on the command line, a 'true' value
-// will be appended to the Verbose field. e.g. when specifying -vvv, the
-// resulting value of Verbose will be {[true, true, true]}.
-//
-// Slice options work exactly the same as primitive type options, except that
-// whenever the option is encountered, a value is appended to the slice.
-//
-// Map options from string to primitive type are also supported. On the command
-// line, you specify the value for such an option as key:value. For example
-//
-//     type Options struct {
-//         AuthorInfo string[string] `short:"a"`
-//     }
-//
-// Then, the AuthorInfo map can be filled with something like
-// -a name:Jesse -a "surname:van den Kieboom".
-//
-// Finally, for full control over the conversion between command line argument
-// values and options, user defined types can choose to implement the Marshaler
-// and Unmarshaler interfaces.
-//
-// Available field tags:
-//     short:          the short name of the option (single character)
-//     long:           the long name of the option
-//     description:    the description of the option (optional)
-//     optional:       whether an argument of the option is optional (optional)
-//     optional-value: the value of an optional option when the option occurs
-//                     without an argument. This tag can be specified multiple
-//                     times in the case of maps or slices (optional)
-//     default:        the default value of an option. This tag can be specified
-//                     multiple times in the case of slices or maps (optional).
-//     default-mask:   when specified, this value will be displayed in the help
-//                     instead of the actual default value. This is useful
-//                     mostly for hiding otherwise sensitive information from
-//                     showing up in the help. If default-mask takes the special
-//                     value "-", then no default value will be shown at all
-//                     (optional)
-//     required:       whether an option is required to appear on the command
-//                     line. If a required option is not present, the parser
-//                     will return ErrRequired.
-//     base:           a base (radix) used to convert strings to integer values,
-//                     the default base is 10 (i.e. decimal) (optional)
-//     value-name:     the name of the argument value (to be shown in the help,
-//                     (optional)
-//     group:          when specified on a struct field, makes the struct field
-//                     a separate group with the given name (optional).
-//     command:        when specified on a struct field, makes the struct field
-//                     a (sub)command with the given name (optional).
-//
-// Either short: or long: must be specified to make the field eligible as an
-// option.
-//
-//
-// Option groups:
-//
-// Option groups are a simple way to semantically separate your options. The
-// only real difference is in how your options will appear in the builtin
-// generated help. All options in a particular group are shown together in the
-// help under the name of the group.
-//
-// There are currently three ways to specify option groups.
-//
-//     1. Use NewNamedParser specifying the various option groups.
-//     2. Use AddGroup to add a group to an existing parser.
-//     3. Add a struct field to the toplevel options annotated with the
-//        group:"group-name" tag.
-//
-//
-//
-// Commands:
-//
-// The flags package also has basic support for commands. Commands are often
-// used in monolithic applications that support various commands or actions.
-// Take git for example, all of the add, commit, checkout, etc. are called
-// commands. Using commands you can easily separate multiple functions of your
-// application.
-//
-// There are currently two ways to specifiy a command.
-//
-//     1. Use AddCommand on an existing parser.
-//     2. Add a struct field to your options struct annotated with the
-//        command:"command-name" tag.
-//
-// The most common, idiomatic way to implement commands is to define a global
-// parser instance and implement each command in a separate file. These
-// command files should define a go init function which calls AddCommand on
-// the global parser.
-//
-// When parsing ends and there is an active command and that command implements
-// the Commander interface, then its Execute method will be run with the
-// remaining command line arguments.
-//
-// Command structs can have options which become valid to parse after the
-// command has been specified on the command line. It is currently not valid
-// to specify options from the parent level of the command after the command
-// name has occurred. Thus, given a toplevel option "-v" and a command "add":
-//
-//     Valid:   ./app -v add
-//     Invalid: ./app add -v
-//
