\subsection{XScreenSaver}
%
% Do we really want info on this single (probably most-used) sipb
% provided program here?
%
Included here should be collected XScreenSaver lore, such as

\begin{itemize}
\item[] The Athena 20 minute rule, and how we finally decided to put
in code to recognize it.
\item[] Various other flaming about it in the past (logging in
particular.)
\item[] Why is the RS/6000 special? (/etc/security, gid 7, HFT)
\item[] What is the ``xfree'' program, and why did we need it?
\item[] Why doesn't xscreensaver use Kerberos?
\end{itemize}
