-/**
- * 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

- * string as output.
- *
- * PHP 5 or higher is required.
