+ // NOTE! plugins here MUST assign output to template
+ // and NOT echo anything directly!! A common
+ // approach is if a plugin decides it needs to
+ // put something at page-top after the standard
+ // SM page header, to dynamically add itself to
+ // the page_header_bottom and/or compose_header_bottom
+ // hooks for the current page request. See
+ // the Sent Confirmation v1.7 or Restrict Senders v1.2
+ // plugins for examples of this approach.
