-* @author Gaetano Giunta
-* @version $Id: $
-*
-* Please note, this is a brutal and simple conversion : it could undoubtedly be
-* improved, as a PHP implementation, by applying more PHP-specific programming
-* features.
-*
-* Exceptions and all PHP 5 - only features ahve been removed for compat with PHP 4
-*
-* Note : whereas jsmin.c works specifically with the standard input and output
-* streams, this implementation only falls back on them if file pathnames are
-* not provided to the JSMin() constructor.
-*
-* Examples comparing with the application compiled from jsmin.c :
-*
-* jsmin < orig.js > mini.js JSMin.php orig.js mini.js
-* JSMin.php orig.js > mini.js
-* JSMin.php - mini.js < orig.js
-* jsmin < orig.js JSMin.php orig.js
-* JSMin.php orig.js -
-* jsmin > mini.js JSMin.php - mini.js
-* JSMin.php > mini.js
-* jsmin comm1 comm2 < a.js > b.js JSMin.php a.js b.js comm1 comm2
-* JSMin.php a.js b.js -c comm1 comm2
-* JSMin.php a.js --comm comm1 comm2 > b.js
-* JSMin.php -c comm1 comm2 < a.js > b.js
-* (etc...)
-*
-* See JSMin.php -h (or --help) for command-line documentation.
-*
-* NEW AND IMPROVED in version 0.2:
-* to take advantage of this file in your own code, you can do the following:
-*
-* define('JSMIN_AS_LIB', true); // prevents auto-run on include
-* include('jsmin.php');
-* // the JSMin class now works on php strings, too
-* $jsMin = new JSMin(file_get_contents('e:/htdocs/awstats_misc_tracker.js'), false);
-* // in that case, the modifies string is returned by minify():
-* $out = $jsMin->minify();
