Server Buffer Format
--------------------
You can change the look of the server buffer lines by changing the
`gnus-server-line-format' variable. This is a `format'-like variable,
with some simple extensions:
`h'
How the news is fetched--the backend name.
`n'
The name of this server.
`w'
Where the news is to be fetched from--the address.
`s'
The opened/closed/denied status of the server.
The mode line can also be customized by using the
`gnus-server-mode-line-format' variable. The following specs are
understood:
`S'
Server name.
`M'
Server method.
