+ * 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
