-Package pflag is a drop-in replacement for Go's flag package, implementing
-POSIX/GNU-style --flags.
-
-pflag is compatible with the GNU extensions to the POSIX recommendations
-for command-line options. See
-http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
-
-Usage:
-
-pflag is a drop-in replacement of Go's native flag package. If you import
-pflag under the name "flag" then all code should continue to function
-with no changes.
-
-	import flag "github.com/ogier/pflag"
-
-	There is one exception to this: if you directly instantiate the Flag struct
-there is one more field "Shorthand" that you will need to set.
-Most code never instantiates this struct directly, and instead uses
-functions such as String(), BoolVar(), and Var(), and is therefore
-unaffected.
-
-Define flags using flag.String(), Bool(), Int(), etc.
-
-This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
-	var ip = flag.Int("flagname", 1234, "help message for flagname")
-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")
-For such flags, the default value is just the initial value of the variable.
-
-After all flags are defined, call
-	flag.Parse()
-to parse the command line into the defined flags.
-
-Flags may then be used directly. If you're using the flags themselves,
-they are all pointers; if you bind to variables, they're values.
-	fmt.Println("ip has value ", *ip)
-	fmt.Println("flagvar has value ", flagvar)
-
-After parsing, the arguments after the flag are available as the
-slice flag.Args() or individually as flag.Arg(i).
-The arguments are indexed from 0 through flag.NArg()-1.
-
-The pflag package also defines some new functions that are not in flag,
-that give one-letter shorthands for flags. You can use these by appending
-'P' to the name of any function that defines a flag.
-	var ip = flag.IntP("flagname", "f", 1234, "help message")
-	var flagvar bool
-	func init() {
-		flag.BoolVarP("boolname", "b", true, "help message")
-	}
-	flag.VarP(&flagVar, "varname", "v", 1234, "help message")
-Shorthand letters can be used with single dashes on the command line.
-Boolean shorthand flags can be combined with other shorthand flags.
-
-Command line flag syntax:
-	--flag    // boolean flags only
-	--flag=x
-
-Unlike the flag package, a single dash before an option means something
-different than a double dash. Single dashes signify a series of shorthand
-letters for flags. All but the last shorthand letter must be boolean flags.
-	// boolean flags
-	-f
-	-abc
-	// non-boolean flags
-	-n 1234
-	-Ifile
-	// mixed
-	-abcs "hello"
-	-abcn1234
-
-Flag parsing stops after the terminator "--". Unlike the flag package,
-flags can be interspersed with arguments anywhere on the command line
-before this terminator.
-
-Integer flags accept 1234, 0664, 0x1234 and may be negative.
-Boolean flags (in their long form) accept 1, 0, t, f, true, false,
-TRUE, FALSE, True, False.
-Duration flags accept any input valid for time.ParseDuration.
-
-The default set of command-line flags is controlled by
-top-level functions.  The FlagSet type allows one to define
-independent sets of flags, such as to implement subcommands
-in a command-line interface. The methods of FlagSet are
-analogous to the top-level functions for the command-line
-flag set.
