This requires Winnitron Launcher v2.1 or greater. It will not work with v2.0.
Despite all our best efforts, sometimes the Winnitron Launcher crashes. This script checks that process is running (the launcher writes its pid and executable path to a file on launch) and then restarts it if it's not running.
Ain't pretty but the more failsafes the better, I say.
Download the exe file from the releases page. All you have to do is run it on your Winnitron (for example, have it run on startup along with the Launcher). On starting, launcher_keep_awake waits five minutes, and then begins checking for a running instance of the Launcher every 30s thereafter.
