 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.

 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.
