\topic{NAME}

\noindent
Name of the protocol.  This name, given in all lower-case letters, can
be given as an argument to {\var xGetProtlByName} to get a capability
for (pointer to) the protocol.  Note that there are multiple
implementations of various protocols; i.e., a given name might map to
multiple implementations.  The implementation bound to a name in a
given kernel is set in {\var graph.comp}.

\topic{SPECIFICATION}

\noindent
Reference to a document that gives the specification for the protocol.
In cases where no formal specification exists, this section gives a
high-level description of the protocol.

\topic{SYNOPSIS}

\noindent
A brief description of what the protocol does.  Outlines any unusual
features and bugs, including any features of the protocol
specification not implemented.

\topic{REALM}

\noindent
Indicates whether the protocol is in the ASYNC realm (supporting push,
demux and pop), the RPC realm (supporting call, calldemux and
callpop), the CONTROL realm (existing only to allow control
operations), or the ANCHOR realm (interfacing with the host system).

\topic{PARTICIPANTS}

\noindent
A discussion of the number of participants the protocol expects to see
and what it expects to see on the participants' stacks.

\topic{CONTROL OPERATIONS}

\noindent
Non-standard control operations supported by the protocol.  For each
control operation, the type of the input and output argument is given
(i.e., the type used to interpret the buffer argument).  In the case
of control operations that take multiple arguments, a set of types is
given.  Non-primitive types are generally defined in the protocol's
{\var .h} file.

\topic{EXTERNAL INTERFACE}

\noindent
A description of interfaces not encapsulated within {\xk} operations

\topic{CONFIGURATION}

\noindent
A description of configuration options for the protocol, including
descriptions of of what this protocol expects of the protocols below
it.  If the protocol can only be configured above a certain protocol,
the appropriate {\var graph.comp} line is given explicitly.

\topic{AUTHORS}

\noindent
Who to complain to if the protocol fails to work as advertised.
