+\section{Key Bindings}

+{\notefont All key bindings are only available when the global Rudel
+minor mode is active. See ``Minor Modes'' below.}
+
+\subsection{Hosting and Joining}
+
+\wkey{Join a Rudel session}{\ccc j}
+\wkey{Leave a Rudel session}{\ccc e}
+
+\wkey{Host a Rudel session}{\ccc h}
+
+\subsection{In a Session}
+
+The following commands are available once a Rudel session has been
+joined:
+
+\key{Change color}{\ccc c}
+
+\key{Create and publish document for buffer}{\ccc p}
+\key{Subscribe to a document}{\ccc s}
+
+The following commands are only available if the current buffer has an
+associated document (achieved by publishing or subscribing):
+
+\key{Detach buffer from document (unsubscribe)}{\ccc u}
+
+\section{Minor Modes}
+
+\subsection{Global Rudel Minor Mode}
+
+The global Rudel minor mode global-rudel-minor-mode is responsible for
+installing the Rudel menu and keymap.
+
+\subsection{Participants in Header Line}
+
+The mode ({\tt rudel-header-subscriptions-minor-mode}) shows
+subscribed users in the header line of the buffer.
+
+The associated global mode ({\tt global-rudel-header-subscriptions
+mode}) turns the mode on or off in all suitable buffers.
+
+\subsection{Buffer Status in Mode Line}
+
+The mode ({\tt rudel-mode-line-publish-state-minor-mode}) shows the
+publication state of the buffer in its mode line ({\tt P}: published,
+{\tt -}: not published)
+
+The associated global mode ({\tt
+global-rudel-mode-line-publish-state-mode}) turns the mode on or off
+in all suitable buffers.
+
+\eject
+
+\section{Backends}
+
+\lesssectionskip
+In Rudel, various kinds of backends are used to provide multiple
+pluggable implementations of functionalities like communication
+protocols, network transport, session initiation and parts of the user
+interface.
+
+\subsection{Protocol}
+
+{\bf Obby}
+
+This backend implements the obby protocol used by the Gobby
+collaborative editor until (including) version 4.9.
+
+\subsection{Session Initiation}
+
+{\bf Configured Sessions}
+
+Frequently used sessions can be configured permanently using the {\tt
+rudel-configured-sessions} customization variable. When there are
+configured sessions, connecting to one of these session is offered
+when joining a session using \kbd{\ccc j}.
+
+{\bf Zeroconf}
+
+The Zeroconf backends discovers collaboration sessions which are
+advertised using, well Zeroconf. Currently, it works for Rudel (obby
+backend) and Obby servers. When there are Zeroconf-advertised
+sessions, using \kbd{\ccc j} to join a session will display these
+sessions.
+
+\section{Examples}
+
+\subsection{Joining a Session with the obby backend}
+
+{\bf Without Zeroconf Discovery}
+
+\kbd{\ccc j}\hfil\break
+{\tt Server: }{\it SERVER} \kbd{RET}\hfil\break

+\section{Key Bindings}
+
+\lesssectionskip
+{\notefont All key bindings are only available when the global Rudel
+minor mode is active. See ``Minor Modes'' below.}
+
+\subsection{Hosting and Joining}
+
+\wkey{Join a Rudel session}{\ccc j}
+\wkey{Leave a Rudel session}{\ccc e}
+
+\wkey{Host a Rudel session}{\ccc h}
+
+\subsection{In a Session}
+
+The following commands are available once a Rudel session has been
+joined:
+
+\key{Change color}{\ccc c}
+
+\key{Create and publish document for buffer}{\ccc p}
+\key{Subscribe to a document}{\ccc s}
+
+The following commands are only available if the current buffer has an
+associated document (achieved by publishing or subscribing):
+
+\key{Detach buffer from document (unsubscribe)}{\ccc u}
+
+\section{Minor Modes}
+
+\subsection{Global Rudel Minor Mode}
+
+The global Rudel minor mode global-rudel-minor-mode is responsible for
+installing the Rudel menu and keymap.
+
+\subsection{Participants in Header Line}
+
+The mode ({\tt rudel-header-subscriptions-minor-mode}) shows
+subscribed users in the header line of the buffer.
+
+The associated global mode ({\tt global-rudel-header-subscriptions
+mode}) turns the mode on or off in all suitable buffers.
+
+\subsection{Buffer Status in Mode Line}
+
+The mode ({\tt rudel-mode-line-publish-state-minor-mode}) shows the
+publication state of the buffer in its mode line ({\tt P}: published,
+{\tt -}: not published)
+
+The associated global mode ({\tt
+global-rudel-mode-line-publish-state-mode}) turns the mode on or off
+in all suitable buffers.

+\section{Backends}
+
+\lesssectionskip
+In Rudel, various kinds of backends are used to provide multiple
+pluggable implementations of functionalities like communication
+protocols, network transport, session initiation and parts of the user
+interface.
+
+\subsection{Protocol}
+
+{\bf Obby}
+
+This backend implements the obby protocol used by the Gobby
+collaborative editor until (including) version 4.9.
+
+\subsection{Session Initiation}
+
+{\bf Configured Sessions}
+
+Frequently used sessions can be configured permanently using the {\tt
+rudel-configured-sessions} customization variable. When there are
+configured sessions, connecting to one of these session is offered
+when joining a session using \kbd{\ccc j}.
+
+{\bf Zeroconf}
+
+The Zeroconf backends discovers collaboration sessions which are
+advertised using, well Zeroconf. Currently, it works for Rudel (obby
+backend) and Obby servers. When there are Zeroconf-advertised
+sessions, using \kbd{\ccc j} to join a session will display these
+sessions.
+
+\section{Examples}
