-/**

- * Combines multiple javascript files and serve up as gzip if possible.

- * Allowable scripts and script dependencies can be specified in a "packages.php" file

- * with the following format. This "packages.php" is optional, if absent the filenames

- * without ".js" extension are used.

- *

- * <code>

- * <?php

- *  $packages = array(

- *     'package1' => array('file1.js', 'file2.js'),

- *     'package2' => array('file3.js', 'file4.js'));

- *

- *  $dependencies = array(

- *     'package1' => array('package1'),

- *     'package2' => array('package1', 'package2')); //package2 requires package1 first.

- * </code>

- *

- * To serve up 'package1', specify the url, a maxium of 25 packages separated with commas is allows.

- *

- * clientscripts.php?js=package1

- *

- * for 'package2' (automatically resolves 'package1') dependency

- *

- * clientscripts.php?js=package2

- *

- * The scripts comments are removed and whitespaces removed appropriately. The

- * scripts may be served as zipped if the browser and php server allows it. Cache

- * headers are also sent to inform the browser and proxies to cache the file.

- * Moreover, the post-processed (comments removed and zipped) are saved in this

- * current directory for the next requests.

- *

- * If the url contains the parameter "mode=debug", the comments are not removed

- * and headers invalidating the cache are sent. In debug mode, the script can still

- * be zipped if the browser and server supports it.

- *

- * E.g. clientscripts.php?js=package2&mode=debug

+/**

+ * jsmin.php - PHP implementation of Douglas Crockford's JSMin.

+ *

+ * This is pretty much a direct port of jsmin.c to PHP with just a few

+ * PHP-specific performance tweaks. Also, whereas jsmin.c reads from stdin and

+ * outputs to stdout, this library accepts a string as input and returns another

+ * string as output.

+ *

+ * PHP 5 or higher is required.

+ *

+ * Permission is hereby granted to use this version of the library under the

+ * same terms as jsmin.c, which has the following license:

+ *

+ * --
