/*
Package flag implements command-line flag parsing.

# Usage

Define flags using [flag.String], [Bool], [Int], etc.

This declares an integer flag, -n, stored in the pointer nFlag, with type *int:

	import "flag"
	var nFlag = flag.Int("n", 1234, "help message for flag n")

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

	var flagvar int
