;; copying, restoring, etc.
;;
;; Todo:
-;; * Replace create-directory with target-prefix, so the maildirs can be in
-;; the same directory as the symlinks, starting with, e.g., ".".
;; * Add a hook for when moving messages from new/ to cur/, to support
;; nnmail's duplicate detection.
-;; * Allow each mark directory in a group to have its own inode for mark
-;; files, to accommodate AFS.
;; * Improve generated Xrefs, so crossposts are detectable.
;; * Improve code readability.
