Why Grunt sux and Gulp rules:

Grunt.js

grunt.initConfig({
	curl: {
		'/tmp/myDonwloadedFile.tar.gz': 'https://gitlab.fronter.net/facilitation/selenium-browser-drivers/raw/master/v1.0.0.tar.gz',
	},
	untar: {
	    options: {
	      	mode: 'tgz'
	    },
	    files: {
	      	'selenium/browser-drivers': '/tmp/myDonwloadedFile.tar.gz'
	    }
	},
	remove: {
	    options: {
	    	trace: true
	    },
	    fileList: ['/tmp/myDonwloadedFile.tar.gz']
	}
});

grunt.registerTask('install-selenium', [
  ['curl', 'untar', 'remove']
]);

Gulp.js

gulp.task('install-selenium', function () {
    plugins.download(
            'https://gitlab.fronter.net/facilitation/selenium-browser-drivers/raw/master/v1.0.0.tar.gz')
        .pipe(plugins.gunzip())
        .pipe(plugins.untar())
        .pipe(gulp.dest('selenium/browser-drivers/'));
});

And the Grunt could be even bigger if we did the gunzip-ing and untar-ing in two steps!

Ha ha. You'd be surprised that a lot of devs are comfortable with grunt syntax. I use gulp at home btw so poo to your hating.
