 // Package envflag is an extremely small bit of code to make configuration
 // via environment variables a little bit less of a hassle when using
 // the flag package in the standard library.
+//
+// Example:
+//
+//	package main
+//
+//	import (
+//		"flag"
+//		"fmt"
+//		"os"
+//
+//		"riedstra.dev/go/envflag"
+//	)
+//
+//	func main() {
+//		fl := flag.NewFlagSet("envflag", flag.ExitOnError)
+//
+//		var aFlag string = "some default"
+//		fmt.Println("aFlag:", aFlag)
+//
+//		envflag.String(fl, &aFlag, "a", "FLAG_A", "Set's the value of -a")
+//
+//		// By default, command line flags override environment vars.
+//		fl.Parse(os.Args[1:])
+//
+//		fmt.Println("aFlag:", aFlag)
+//	}
+//
+// Known caveat, variables set in the environment will override what the flag
+// package sees as the "default" value.
