+ * read_headers.tpl
+ *
+ * Template to display the envelope headers when viewing a message.
+ * 
+ * The following variables are available in this template:
+ * 
+ *    $headers_to_display - Array containing the list of all elements that need
+ *                          to be displayed.  The index of each element is the 
+ *                          translated name of the field to be displayed.  The 
+ *                          value of each element is the value to be displayed 
+ *                          for that field.  Many values can be controled through
+ *                          additional templates.
