;;; Commentary:
;;
;; This package provides the following new features for VM:
;;
;; A Pine-like postpone message function and folder. There are two new
;; functions. `vm-postpone-message' bound to [C-c C-d] in
;; the `vm-mail-mode' and the function `vm-continue-postponed-message'
;; is bound to [C] in a folder buffer.
;;
;; Typical usage: If you are writing a mail message, and you wish to
;; postpone it for a while, hit C-c C-d. The message will be saved in
;; a folder called "postponed" by default. Later, when you wish to
;; resume editing that file, visit the "postponed" folder, find the
;; message you wish to continue editing, and then hit C to resume
;; editing.
;;
;; Furthermore, this facility can be configured, using
;; `vm-continue-what-message' to imitate Pine's message composing.
;; You can set `vm-mode-map' in the following way to get Pine-like
;; behaviour:
;;
;; (define-key vm-mode-map "m" 'vm-continue-what-message)
;; (setq vm-zero-drafts-start-compose t)
;;
;; If you have postponed messages you will be asked if you want to continue
;; composing them, if you say "yes" you will visit the `vm-postponed-folder'
;; and you can select the message you would like to continue and press "m"
;; again! However be aware this works currently only if you expunge all
;; messages marked for deletion and save the postponed folder.
;;
;; You can also bind it to "C-x m" in order to check for postponed messages
;; when composing a message without starting VM.
;;
;; (autoload 'vm-continue-what-message-other-window "vm-pine" "" t)
;; (global-set-key "\C-xm" 'vm-continue-what-message-other-window)
;;
;;
;; Three new mail header insertion functions make life easier. The
;; bindings and names are:
;; "\C-c\C-f\C-a" vm-mail-return-receipt-to
;; "\C-c\C-f\C-p" vm-mail-priority
;; "\C-c\C-f\C-f" vm-mail-fcc
;; The variables `vm-mail-return-receipt-to' and `vm-mail-priority'
;; can be used to configure the inserted headers.
;; `vm-mail-fcc' can be configured by setting the variable
;; `vm-mail-folder-alist' which has the same syntax and default
;; value as `vm-auto-folder-alist'.
;; You may also add `vm-mail-auto-fcc' to `vm-reply-hook' in order to
;; automatically setup the FCC header according to the variable
;; `vm-mail-folder-alist'.
;; There is another fcc-function `vm-mail-to-fcc' which set the FCC
;; according to the recipients email-address.
;;
;;; Bug reports and feature requests:
;; Please send a backtrace and the version number of vm-pine.el!
;; Feature requests are welcome!
