;;; Commentary:
-;; These macros may look very much like the ones in GNUS 4.1. They
-;; are, in a way, but you should note that the indices they use have
-;; been changed from the internal GNUS format to the NOV format. The
-;; makes it possible to read headers from XOVER much faster.
-;;
-;; The format of a header is now:
-;; [number subject from date id references chars lines xref]
-;;
-;; (That last entry is defined as "misc" in the NOV format, but Gnus
-;; uses it for xrefs.)

(eval-when-compile (require 'cl))
