-# Parse Flags From CLI Arguments
-
-Though we can grab the arguments to a Go program from `os.Args`, it requires
-some manual parsing. With the built-in `flag` package, we can declare specific
-flags our program accepts, by type. When we parse them, they will be separated
-out from the rest of the positional arguments.
-
-Here is an example of the program that accepts a boolean `debug` flag. This
-will work with either `-debug` or `--debug`.
-
-```go
-package main
-
-import (
-	"flag"
-	"fmt"
-	"os"
-)
-
-func main() {
-	var debug bool
-	flag.BoolVar(&debug, "debug", false, "turns on debug mode, extra logging")
-	flag.Parse()
-
-	positionalArgs := flag.Args()
-
-	if len(positionalArgs) < 1 {
-		fmt.Println("Please specify which part to run: 1 or 2")
-		os.Exit(1)
-	}
-
-	if debug {
-		fmt.Println("We are in debug mode...")
-		fmt.Println("Received the following argument:", positionalArgs[0])
-	}
-
-	// ...
-}
-```
-
-We can run the program in debug mode like so:
-
-```bash
-$ go run . --debug 123
-We are in debug mode...
-Received the following argument: 123
-```
-
-We can also take advantage of the `help` flag that we get for free:
-
-```bash
-$ go run . --help
-Usage of /var/folders/62/lx9pcjbs1zbd83zg6twwym2r0000gn/T/go-build3212087168/b001/exe/test:
-  -debug
-        turns on debug mode, extra logging
-```
-
-Note: any recognized flags need to come before any of the position arguments.
-The `debug` flag won't be picked up if we run the program like this:
-
-```bash
-$ go run . 123 --debug
-```
