;;; Commentary:
+;; This is the gnus-registry.el package, which works with all
+;; backends, not just nnmail (e.g. NNTP). The major issue is that it
+;; doesn't go across backends, so for instance if an article is in
+;; nnml:sys and you see a reference to it in nnimap splitting, the
+;; article will end up in nnimap:sys
+
+;; gnus-registry.el intercepts article respooling, moving, deleting,
+;; and copying for all backends. If it doesn't work correctly for
+;; you, submit a bug report and I'll be glad to fix it. It needs
+;; documentation in the manual (also on my to-do list).
+
+;; Put this in your startup file (~/.gnus.el for instance)
+
+;; (require 'nnregistry) ;; optional, or see below (automatically calls `gnus-registry-install-nnregistry' when `gnus-registry-initialize' is called)
+;; (setq gnus-registry-max-entries 2500
+;; gnus-registry-use-long-group-names t)
+
+;; (gnus-registry-initialize)
+;; (gnus-registry-install-nnregistry) ;; optional, or see above (loading nnregistry makes it unnecessary)
+
+;; Then use this in your fancy-split:
+
+;; (: gnus-registry-split-fancy-with-parent)
+
+;; TODO:
+
+;; - get the correct group on spool actions
+
+;; - articles that are spooled to a different backend should be handled
