-Zephyr was a system designed to let system administrators send
-important messages to users in an easily noticeable format. It was
-meant to have a low volume of traffic and be used only for official
-notices. This is obviously not what Zephyr is today. It can still be
-used in the way it was intended: notice that you get official
-zephyrgrams as you log in, with important information about Athena
-services and planned outages. However, the most common usage is by
-average users exchanging information about classes, how their days are
-going, and talking on Zephyr classes and instances about everything
-from the latest episode of Battlestar Galactica to the next 18.03
-problem set. The usage of Zephyr has far exceeded original
-expectations. Over time, people have also created programs that give
-Zephyr a graphical interface, and programs that give zephyr a purely
-textual interface, that can be used entirely within a ssh
-terminal. Some of these zephyr clients have become so widely used that
-there are users who do not know that there are other ways to send (and
-receive) zephyrgrams. This wiki will cover the traditional commands,
-typed at the athena% prompt, as well as the more common modern zephyr
-client Barnowl.
-
-The information in this wiki about Barnowl just barely touches the
-surface. More for in-depth functionality, visit the [Barnowl

-## Modern Zephyr
-
-Today the majority of Zephyr users use the barnowl client. There are
-other clients as well (for example, Pidgin supports Zephyr). The
-following sections will go into detail about how to install, use, and
-customize barnowl.

-### Other Clients
-
-There are other clients besides Barnowl, however their use is not
-nearly as widespread. Some of these include:
