Misc Article
============

`gnus-single-article-buffer'
     If non-`nil', use the same article buffer for all the groups.
     (This is the default.)  If `nil', each group will have its own
     article buffer.

`gnus-article-prepare-hook'
     This hook is called right after the article has been inserted into
     the article buffer.  It is mainly intended for functions that do
     something depending on the contents; it should probably not be
     used for changing the contents of the article buffer.

`gnus-article-display-hook'
     This hook is called as the last thing when displaying an article,
     and is intended for modifying the contents of the buffer, doing
     highlights, hiding headers, and the like.

`gnus-article-mode-hook'
     Hook called in article mode buffers.

`gnus-article-mode-line-format'
     This variable is a format string along the same lines as
     `gnus-summary-mode-line-format'.  It accepts exactly the same
     format specifications as that variable.

`gnus-break-pages'
     Controls whether "page breaking" is to take place.  If this
     variable is non-`nil', the articles will be divided into pages
     whenever a page delimiter appears in the article.  If this
     variable is `nil', paging will not be done.

`gnus-page-delimiter'
     This is the delimiter mentioned above.  By default, it is `^L'
     (form linefeed).
