You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: staple.go
    path of file: ./repos/gon/staple
    
    the code of the file until where you have to start completion: // Package staple staples a notarization ticket to a file, allowing it
// to be validated offline. This only works for files of type "app", "dmg",
// or "pkg".
package staple

import (
	"bytes"
	"context"
	"fmt"
	"os/exec"
	"path/filepath"

	"github.com/hashicorp/go-hclog"
)

// Options are the options for creating the zip archive.

	// Build our command
	var cmd exec.Cmd
	if opts.BaseCmd != nil {

	// We only set the path if it isn't set. This lets the options set the
	// path to the codesigning binary that we use.
	if cmd.Path == "" {
		path, err := exec.LookPath("xcrun")
		if err != nil {
			return err
		}
		cmd.Path = path
	}

	cmd.Args = []string{
		filepath.Base(cmd.Path),
		"stapler",
		"staple",
		opts.File,
	}

	// We store all output in out for logging and in case there is an error
	var out bytes.Buffer
	cmd.Stdout = &out
