-;;
-;; This is the beginning of a solution for storing sent mail in a
-;; maildir in emacs message mode, presented because some people might
-;; find it useful. It is *not* fully tested, it *may* overwrite files,
-;; and any directories you point this at may no longer be there
-;; afterwards. Use at your own risk.
-;;
-;; To use this as the fcc handler for message-mode, put
-;; one of the following in your init file:
-;;
-;; if you want Fcc'd messages to be marked as read:
-;;
-;; (setq message-fcc-handler-function
-;; '(lambda (destdir)
-;; (notmuch-maildir-fcc-write-buffer-to-maildir destdir t)))
-;;
-;; if you want Fcc'd messages to be marked as new:
-;;
-;; (setq message-fcc-handler-function
-;; '(lambda (destdir)
-;; (notmuch-maildir-fcc-write-buffer-to-maildir destdir nil)))

+
+Three types of values are permitted:
+
+- nil: no Fcc header is added,
+
+- a string: the value of `notmuch-fcc-dirs' is the Fcc header to
+ be used.
+
+- a list: the folder is chosen based on the From address of the
+ current message using a list of regular expressions and
+ corresponding folders:
+
+ ((\"Sebastian@SSpaeth.de\" . \"privat\")
+ (\"spaetz@sspaeth.de\" . \"OUTBOX.OSS\")
+ (\".*\" . \"defaultinbox\"))
+
+ If none of the regular expressions match the From address, no
+ Fcc header will be added.
+
+If `notmuch-maildir-use-notmuch-insert' is set (the default) then
+the header should be of the form \"folder +tag1 -tag2\" where
+folder is the folder (relative to the notmuch mailstore) to store
+the message in, and tag1 and tag2 are tag changes to apply to the
+stored message. This string is split using `split-string-and-unquote',
+so a folder name containing spaces can be specified by
+quoting each space with an immediately preceding backslash
+or surrounding the entire folder name in double quotes.
+
+If `notmuch-maildir-use-notmuch-insert' is nil then the Fcc
+header should be the directory where the message should be
+saved. A relative directory will be understood to specify a
+directory within the notmuch mail store, (as set by the
+database.path option in the notmuch configuration file).
