-In the PC world people often talk about ``offline'' newsreaders.  These
-are thingies that are combined reader/news transport monstrosities.
-With built-in modem programs.  Yecchh!
-Of course, us Unix Weenie types of human beans use things like
-@code{uucp} and, like, @code{nntpd} and set up proper news and mail
-transport things like Ghod intended.  And then we just use normal
-newsreaders.
-However, it can sometimes be convenient to do something that's a bit
-easier on the brain if you have a very slow modem, and you're not really
-that interested in doing things properly.
-A file format called @sc{soup} has been developed for transporting news
-and mail from servers to home machines and back again.  It can be a bit
-fiddly.
-First some terminology:
-@table @dfn
-@item server
-This is the machine that is connected to the outside world and where you
-get news and/or mail from.
-@item home machine
-This is the machine that you want to do the actual reading and responding
-on.  It is typically not connected to the rest of the world in any way.
-@item packet
-Something that contains messages and/or commands.  There are two kinds
-of packets:
-@table @dfn
-@item message packets
-These are packets made at the server, and typically contain lots of
-messages for you to read.  These are called @file{SoupoutX.tgz} by
-default, where @var{x} is a number.
-@item response packets
-These are packets made at the home machine, and typically contains
-replies that you've written.  These are called @file{SoupinX.tgz} by
-default, where @var{x} is a number.
-@end table
-@end table
-@enumerate
-@item
-You log in on the server and create a @sc{soup} packet.  You can either
-use a dedicated @sc{soup} thingie (like the @code{awk} program), or you
-can use Gnus to create the packet with its @sc{soup} commands (@kbd{O
-s} and/or @kbd{G s b}; and then @kbd{G s p}) (@pxref{SOUP Commands}).
-@item
-You transfer the packet home.  Rail, boat, car or modem will do fine.
-@item
-You put the packet in your home directory.
-@item
-You fire up Gnus on your home machine using the @code{nnsoup} back end as
-the native or secondary server.
-@item
-You read articles and mail and answer and followup to the things you
-want (@pxref{SOUP Replies}).
-@item
-You do the @kbd{G s r} command to pack these replies into a @sc{soup}
-packet.
-@item
-You transfer this packet to the server.
-@item
-You use Gnus to mail this packet out with the @kbd{G s s} command.
-@item
-You then repeat until you die.
-@end enumerate

-These are the variables you can use to customize its behavior:
-@table @code
-@item nnsoup-tmp-directory
-@vindex nnsoup-tmp-directory
-When @code{nnsoup} unpacks a @sc{soup} packet, it does it in this

-@code{nnsoup} then moves each message and index file to this directory.
-The default is @file{~/SOUP/}.
-@item nnsoup-replies-directory
-@vindex nnsoup-replies-directory
-All replies will be stored in this directory before being packed into a
-reply packet.  The default is @file{~/SOUP/replies/}.
-@item nnsoup-replies-format-type
-@vindex nnsoup-replies-format-type
-The @sc{soup} format of the replies packets.  The default is @samp{?n}
-(rnews), and I don't think you should touch that variable.  I probably
-shouldn't even have documented it.  Drats!  Too late!
-@item nnsoup-replies-index-type
-@vindex nnsoup-replies-index-type
-The index type of the replies packet.  The default is @samp{?n}, which
-means ``none''.  Don't fiddle with this one either!
-@item nnsoup-active-file
-@vindex nnsoup-active-file
-Where @code{nnsoup} stores lots of information.  This is not an ``active
-file'' in the @code{nntp} sense; it's an Emacs Lisp file.  If you lose
-this file or mess it up in any way, you're dead.  The default is
-@file{~/SOUP/active}.
-@item nnsoup-packer
-@vindex nnsoup-packer
-Format string command for packing a reply @sc{soup} packet.  The default
-is @samp{tar cf - %s | gzip > $HOME/Soupin%d.tgz}.
-@item nnsoup-unpacker

-@subsubsection SOUP Replies
-Just using @code{nnsoup} won't mean that your postings and mailings end
-up in @sc{soup} reply packets automagically.  You have to work a bit
-more for that to happen.
-@findex nnsoup-set-variables
-The @code{nnsoup-set-variables} command will set the appropriate
-variables to ensure that all your followups and replies end up in the
-@sc{soup} system.
-In specific, this is what it does:
-@lisp
-(setq message-send-news-function 'nnsoup-request-post)
-(setq message-send-mail-function 'nnsoup-request-mail)
-@end lisp
-And that's it, really.  If you only want news to go into the @sc{soup}
-system you just use the first line.  If you only want mail to be
-@sc{soup}ed you use the second.
