- * Options Management Administration Panel.

  *

- * Just allows for displaying of options.
+ * 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 isn't referenced or linked to, but will show all of the options and
- * allow editing. The issue is that serialized data is not supported to be
- * modified. Options can not be removed.
+ * 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.
