Various Various
===============

`gnus-verbose'
     This variable is an integer between zero and ten.  The higher the
     value, the more messages will be displayed.  If this variable is
     zero, Gnus will never flash any messages, if it is seven (which is
     the default), most important messages will be shown, and if it is
     ten, Gnus won't ever shut up, but will flash so many messages it
     will make your head swim.

`gnus-verbose-backends'
     This variable works the same way as `gnus-verbose', but it applies
     to the Gnus backends instead of Gnus proper.

`nnheader-max-head-length'
     When the backends read straight heads of articles, they all try to
     read as little as possible.  This variable (default `4096')
     specifies the absolute max length the backends will try to read
     before giving up on finding a separator line between the head and
     the body.  If this variable is `nil', there is no upper read
     bound.  If it is `t', the backends won't try to read the articles
     piece by piece, but read the entire articles.  This makes sense
     with some versions of `ange-ftp'.

`nnheader-file-name-translation-alist'
     This is an alist that says how to translate characters in file
     names.  For instance, if `:' is illegal as a file character in
     file names on your system (you OS/2 user you), you could say
     something like:

          (setq nnheader-file-name-translation-alist
                '((?: . ?_)))

     In fact, this is the default value for this variable on OS/2 and MS
     Windows (phooey) systems.

`gnus-hidden-properties'
     This is a list of properties to use to hide "invisible" text.  It
     is `(invisible t intangible t)' by default on most systems, which
     makes invisible text invisible and intangible.

`gnus-parse-headers-hook'
     A hook called before parsing headers.  It can be used, for
     instance, to gather statistics on the headers fetched, or perhaps
     you'd like to prune some headers.  I don't see why you'd want
     that, though.
