Example Methods
---------------

   Most select methods are pretty simple and self-explanatory:

     (nntp "news.funet.fi")

   Reading directly from the spool is even simpler:

     (nnspool "")

   As you can see, the first element in a select method is the name of
the backend, and the second is the "address", or "name", if you will.

   After these two elements, there may be a arbitrary number of
(VARIABLE FORM) pairs.

   To go back to the first example--imagine that you want to read from
port `15' from that machine.  This is what the select method should
look like then:

     (nntp "news.funet.fi" (nntp-port-number 15))

   You should read the documentation to each backend to find out what
variables are relevant, but here's an `nnmh' example.

   `nnmh' is a mail backend that reads a spool-like structure.  Say you
have two structures that you wish to access: One is your private mail
spool, and the other is a public one.  Here's the possible spec for you
private mail:

     (nnmh "private" (nnmh-directory "~/private/mail/"))

   (This server is then called `private', but you may have guessed
that.)

   Here's the method for a public spool:

     (nnmh "public"
           (nnmh-directory "/usr/information/spool/")
           (nnmh-get-new-mail nil))
