OK. I've added this:
(info "(gnus)Slow/Expensive Connection")
,----
|`gnus-nov-is-evil'
| This one has to be _always_ `nil' (which is the default). If you
| need not to use NOV (see below) with the `nntp' back end for
| example (*note Crosspost Handling::), set `nntp-nov-is-evil' to a
| non-`nil' value instead of setting this. But you normally have no
| need to set `nntp-nov-is-evil' since Gnus by itself will detect
| whether the NNTP server supports NOV. Anyway, grabbing article
| headers from the NNTP server will not be very fast if you tell
| Gnus not to use NOV.
|
| As the variables for the other back ends, there are
| `nndiary-nov-is-evil', `nndir-nov-is-evil',
| `nnfolder-nov-is-evil', `nnimap-nov-is-evil', `nnml-nov-is-evil',
| `nnspool-nov-is-evil', and `nnwarchive-nov-is-evil'. Note that a
| non-`nil' value for `gnus-nov-is-evil' overrides all those
| variables.
|
|What's NOV?
|
| NOV stands for News OverView, which provide data containing the
|condensed header information of articles. They are what the server
|makes; in the `nntp' back end Gnus uses the ones that the NNTP server
|makes, but Gnus makes them by itself in the server like `nnml' which
|Gnus performs. The NOV data consist of one or more text lines (*note
|Motion by Text Lines: (elisp)Text Lines.) where each line has the header
|information of one article. The header information is a tab-separated
|series of the header's contents including an article number, a subject,
|an author, a date, a message-id, references, etc.
|
| Those data enable Gnus to generate summary lines fast. However, if
|the server does not support NOV or you disable it purposely or for some
|reason, Gnus will try to generate the header information by parsing
|article's header one by one. It will take time. Therefore, it is not
|usually a good idea to set `*-nov-is-evil' to a non-`nil' value unless
|there is such a reason that the server makes wrong NOV data.
