* Options Management Administration Screen.

 * If accessed directly in a browser this page shows a list of all saved options

 * along with editable fields for their values. Serialized data is not supported

 * and there is no way to remove options via this page. It is not linked to from

 * anywhere else in the admin.

 *

 * This file is also the target of the forms in core and custom options pages

 * that use the Settings API. In this case it saves the new option values

 * and returns the user to their page of origin.
