DOS batch file to launch a NodeWebKit app. NodeWebKit has a habit of occasionally immediately quitting when trying to launch it. This script times the launch and quit times, so if the app exits in less than 5 seconds, we re-launch the app, until we finally get a proper launch.

@echo off

	:: Start timer.
	@set /A _tic=%time:~0,2%*3600^
				+%time:~3,1%*10*60^

				+%time:~7,1% >nul

	:: Launch NodeWebKit on the app in the current folder.
	start /wait %~dp0\node_modules\nw\nwjs\nw .

	:: Stop timer.

	:: Get elapsed seconds.
	@set /A _elapsed=%_toc%-%_tic
	@echo %_elapsed% seconds.
