Distribute your Go program (or any single binary) as a native macOS application

	// Package main is a sample macOS-app-bundling program to demonstrate how to
	// automate the process described in this tutorial:

	// https://medium.com/@mattholt/packaging-a-go-application-for-macos-f7084b00f6b5
	//
	// Bundling the .app is the first thing it does, and creating the DMG is the
	// second. Making the DMG is optional, and is only done if you provide
	// the template DMG file, which you have to create beforehand.
	//
	// Example use:

Example of using Keygen's licensing and distribution APIs together to only load an app's main logic for licensed users. The example below uses Keygen's demo account and is fully functional. Download the HTML file and open it in a browser.

	# Copy this snippet below and paste into a terminal to download the HTML file
	# and open it in your default browser
	tmp=$(mktemp /tmp/keygen-XXXXXX) && \
	curl -o "$tmp" https://gist.githubusercontent.com/ezekg/0f87abd27e60be3ffeef02c7c2829319/raw/97b71eb58dcd85383a4c8fccb8ce38c887e0eacb/index.html && \

How to generate an offline-capable license resource, as well as an example of how to validate the license both online and offline. Do note that anything outside of expiry validation cannot be done offline e.g. machine validation, scope requirements, etc. Shell script implementation: https://gist.github.com/ezekg/57d1508fc1557236fe5eb8803e0e47af.

	const fetch = require('node-fetch')
	const NodeRSA = require('node-rsa')
	const crypto = require('crypto')
	const now = new Date()

	// The policy we want to use for generated licenses, as well as the
	// user the license is for. Feel free to omit the user.
	const POLICY_ID = '3bc8bc4c-78fd-4d8b-89dd-f4d2cda1d353'
	const USER_ID = '4796e950-0dcf-4bab-9443-8b406889356f'

Example of using pub/priv keys for license generation, so license's can be validated online and offline. Note: each step should be run separately. Requires the great https://stedolan.github.io/jq/ command line tool. Node implementation: https://gist.github.com/ezekg/f021009b4c419f2462f3706a4478f200.

	# 1. Generate a public/private keypair
	openssl genrsa -out priv.pem 512
	openssl rsa -in priv.pem -out pub.pem -outform PEM -pubout

	# 2. Verify public/private keys look OK
	cat priv.pem pub.pem

	# 3. Generate a key with an expiry in 1 year and sign with private key (server-side)
	#
	# Note: the expiry you choose should match your license's policy, so that online
