10206 ;; call, but it is an opportunity to clean up, if that is needed. It
10207 ;; is called when Gnus exits a group.
10209 ;; `choke-request-article ARTICLE &optional GROUP SERVER'
10210 ;; Return ARTICLE, which is either an article number or
10211 ;; message-id. Note that not all backends can return articles based on
10214 ;; `choke-request-list SERVER'
10215 ;; Return a list of all newsgroups on SERVER.

10222 ;; SERVER. Note that the date doesn't have to be respected - Gnus will
10223 ;; always check whether the groups are old or not. Backends that do

10228 ;; Should return a buffer that is suitable for "posting". nnspool and

10249 ;; Optional function for retrieving active file info on all groups in
10250 ;; GROUPS. Two return formats are supported: The normal active file
10251 ;; format, and a list of GROUP lines. This function should return (as
10252 ;; a function value) either `active' or `group', depending on what
10253 ;; format it returns.
10255 ;; The following functions are optional and apply only to backends
10256 ;; that are able to control the contents of their groups totally
10257 ;; (ie. mail backends.) Backends that aren't able to do that
10258 ;; shouldn't define these functions at all. Gnus will check for their

10268 ;; Removes any information it has added to the article (extra headers,

10286 ;; articles. Note that even headers may be edited, so the backend has
10287 ;; to update any tables (nov buffers, etc) that it maintains after
10288 ;; replacing the article.

10291 ;; Create GROUP on SERVER. This might be a new, empty group, or it
10292 ;; might be a group that already exists, but hasn't been registered
