;;; Commentary:
-;; All the Gnus backends have the same interface, and should return
-;; data in a similar format. Below is an overview of what functions
-;; these packages must supply and what results they should return.
-;;
-;; Variables:
-;;
-;; `nntp-server-buffer' - All data should be returned to Gnus in this
-;; buffer.
-;;
-;; Functions for the imaginary backend `choke':
-;;
-;; `choke-retrieve-headers ARTICLES &optional GROUP SERVER'
-;; Should return all headers for all ARTICLES, or return NOV lines for
-;; the same.
-;;
-;; `choke-request-group GROUP &optional SERVER DISCARD'
-;; Switch to GROUP. If DISCARD is nil, active information on the group
-;; must be returned.
-;;
-;; `choke-close-group GROUP &optional SERVER'
-;; Close group. Most backends won't have to do anything with this
-;; call, but it is an opportunity to clean up, if that is needed. It
-;; is called when Gnus exits a group.
-;;
-;; `choke-request-article ARTICLE &optional GROUP SERVER'
-;; Return ARTICLE, which is either an article number or
-;; message-id. Note that not all backends can return articles based on
-;; message-id.
-;;
-;; `choke-request-list SERVER'
-;; Return a list of all active newsgroups on SERVER.
-;;
-;; `choke-request-list-newsgroups SERVER'
-;; Return a list of descriptions of all newsgroups on SERVER.
-;;
-;; `choke-request-newgroups DATE &optional SERVER'
-;; Return a list of all groups that have arrived after DATE on
-;; SERVER. Note that the date doesn't have to be respected - Gnus will
-;; always check whether the groups are old or not. Backends that do
-;; not store date information may just return the entire list of
-;; groups.
-;;
-;; `choke-request-post-buffer METHOD HEADER ARTICLE-BUFFER GROUP INFO'
-;; Should return a buffer that is suitable for "posting". nnspool and
-;; nntp return a `*post-buffer*', and nnmail return a `*mail*'
-;; buffer. This function should fill out the appropriate headers.
-;;
-;; `choke-request-post &optional SERVER'
-;; Function that will be called from a buffer to be posted.
-;;
-;; `choke-open-server SERVER &optional ARGUMENT'
-;; Open a connection to SERVER.
-;;
-;; `choke-close-server &optional SERVER'
-;; Close the connection to SERVER.
-;;
-;; `choke-server-opened &optional SERVER'
-;; Whether the conenction to SERVER is opened or not.
-;;
-;; `choke-server-status &optional SERVER'
-;; Should return a status string (not in the nntp buffer, but as the
-;; result of the function).
-;;
-;; The following functions are optional and apply only to backends
-;; that are able to control the contents of their groups totally
-;; (ie. mail backends.) Backends that aren't able to do that
-;; shouldn't define these functions at all. Gnus will check for their
-;; presence before attempting to call them.
-;;
-;; `choke-request-expire-articles ARTICLES &optional NEWSGROUP SERVER'
-;; Should expire (according to some aging scheme) all ARTICLES. Most
-;; backends will not be able to expire articles. Should return a list
-;; of all articles that were not expired.
-;;
-;; `choke-request-move-article ARTICLE GROUP SERVER ACCEPT-FORM'
-;; Should move ARTICLE from GROUP on SERVER by using ACCEPT-FORM.
-;; Removes any information it has added to the article (extra headers,
-;; whatever - make it as clean as possible), and then passes the
-;; article on by evaling ACCEPT-FORM, which is normally a call to the
-;; function described below. If the ACCEPT-FORM returns a non-nil
-;; value, the article should then be deleted.
-;;
-;; `choke-request-accept-article GROUP'
-;; The contents of the current buffer will be put into GROUP. There
-;; should, of course, be an article in the current buffer. This
-;; function is normally only called by the function described above.
-;;
-;; `choke-request-replace-article ARTICLE GROUP BUFFER'
-;; Replace ARTICLE in GROUP with the contents of BUFFER.
-;; This provides an easy interface for allowing editing of
-;; articles. Note that even headers may be edited, so the backend has
-;; to update any tables (nov buffers, etc) that it maintains after
-;; replacing the article.
-;;
-;; All these functions must return nil if they couldn't service the
-;; request. If the optional arguments are not supplied, some "current"
-;; or "default" values should be used. In short, one should emulate an
-;; NNTP server, in a way.
-;;
-;; If you want to write a new backend, you just have to supply the
-;; functions listed above. In addition, you must enter the new backend
-;; into the list of valid select methods:
-;; (setq gnus-valid-select-methods
-;; (cons '("choke" mail) gnus-valid-select-methods))
-;; The first element in this list is the name of the backend. Other
-;; elemnets may be `mail' (for mail groups), `post' (for news
-;; groups), `none' (neither), `respool' (for groups that can control
-;; their contents).
