-;; Gnus-Diary is a wrapper around the NNDiary Gnus backend. It is here to
-;; make your nndiary-user life easier in different ways. So, you don't have
-;; to use it if you don't want to. But, really, you should.
-
-;; Gnus-Diary offers the following features on top of the NNDiary backend:
-
-;; - A nice summary line format:
-;; Displaying diary messages in standard summary line format (usually
-;; something like "<From Joe>: <Subject>") is pretty useless. Most of the
-;; time, you're the one who wrote the message, and you mostly want to see
-;; the event's date. Gnus-Diary offers you a nice summary line format
-;; which will do this. By default, a summary line will appear like this:
-;;
-;; <Event Date>: <Subject> <Remaining time>
-;;
-;; for example, here's how Joe's birthday is displayed in my
-;; "nndiary:birhdays" summary buffer (the message is expirable, but will
-;; never be deleted, as it specifies a regular event):
-;;
-;; E Sat, Sep 22 01, 12:00: Joe's birthday (in 6 months, 1 week)
-
-;; - More article sorting functions:
-;; Gnus-Diary adds a new sorting function called
-;; `gnus-summary-sort-by-schedule'. This function lets you organize your
-;; diary summary buffers from the closest event to the farthest one.
-
-;; - Automatic generation of diary group parameters:
-;; When you create a new diary group, or visit one, Gnus-Diary checks your
-;; group parameters, and if needed, sets the summary line format to the
-;; diary-specific value, adds the diary-specific sorting functions, and
-;; also adds the different `X-Diary-*' headers to the group's
-;; posting-style. It is then easier to send a diary message, because if
-;; you use `C-u a' or `C-u m' on a diary group to prepare a message, these
-;; headers will be inserted automatically (but not filled with proper
-;; values yet).
-
-;; - An interactive mail-to-diary convertion function:
-;; The function `gnus-diary-check-message' ensures that the current message
-;; contains all the required diary headers, and prompts you for values /
-;; correction if needed. This function is hooked in the nndiary backend so
-;; that moving an article to an nndiary group will trigger it
-;; automatically. It is also bound to `C-c D c' in message-mode and
-;; article-edit-mode in order to ease the process of converting a usual
-;; mail to a diary one. This function takes a prefix argument which will
-;; force prompting of all diary headers, regardless of their
-;; presence/validity. That way, you can very easily reschedule a diary
-;; message for instance.
-
-
-;; Usage:
-;; =====
-
-;; 0/ Don't use any `gnus-user-format-function-[d|D]'. Gnus-Diary provides
-;; both of these (sorry if you used them before).
-;; 1/ Add '(require 'gnus-diary) to your gnusrc file.
-;; 2/ Customize your gnus-diary options to suit your needs.
