+ *       array is directly placed in Drupal.settings. You might want to wrap 
+ *       your actual configuration settings in another variable to prevent the 
+ *       pollution of the Drupal.settings namespace.
+ * @param $options
+ *   (optional) A string for the type ('file', 'inline', 'setting'), or an array
+ *   which can have any or all of the following keys (these are not valid with 
+ *   type => 'setting'):
+ *   - type
+ *       The type of JavaScript that should be added to the page. Allowed
+ *       values are 'file', 'inline' and 'setting'.
+ *   - scope
+ *       The location in which you want to place the script. Possible
+ *       values are 'header' and 'footer' by default. If your theme implements
+ *       different locations, however, you can also use these.
+ *   - weight
+ *       The weight determines the order of files in output. Lower weights mean
+ *       the scripts are loaded sooner. Default to JS_MODULE_WEIGHT if none 
+ *       specified. Constants are available as JS_CORE_WEIGHT (-20), 
+ *       JS_MODULE_WEIGHT (0), and JS_THEME_WEIGHT (20).
+ *   -  cache
+ *       If set to FALSE, the JavaScript file is loaded anew on every page
+ *       call, that means, it is not cached. Defaults to TRUE. Used only when 
+ *       $type references a JavaScript file.
+ *   - aggregate
+ *       Should this JS file be aggregated if this feature has been turned
+ *       on under the performance section.
+ *   - attributes
+ *       An array of attributes to be added to the script tag. Will be run 
+ *       through drupal_attributes().
+ * @param $reset
+ *   Resets the currently loaded JavaScript.
+ * @return
+ *   An array of JavaScript files to include - the array has three keys:
+ *    - 'file'
+ *        An array of files keyed by path (the value is the $options that was 
+ *        passed in).
+ *    - 'inline'
+ *        An array of code to be put inline.  The key is the code and the value
+ *        is the $options.
+ *    - 'setting'
+ *        This one is different; it is keyed by scope (region to put the
+ *        JavaScript in). Inside each scope is an aggregation of the variables 
+ *        that were added to the settings.
