Remove obsolete \setindexsubitem macros.
Massive migration to methoddesc and memberdesc. Logical markup as needed. A sprinkling of index entries for flavor.

+\end{methoddesc}
-\begin{funcdesc}{send_error}{code\optional{, message}}
+\begin{methoddesc}{send_error}{code\optional{, message}}
Sends and logs a complete error reply to the client. The numeric
\var{code} specifies the HTTP error code, with \var{message} as
optional, more specific text. A complete set of headers is sent,
followed by text composed using the \member{error_message_format}
class variable.
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{send_response}{code\optional{, message}}
+\begin{methoddesc}{send_response}{code\optional{, message}}
Sends a response header and logs the accepted request. The HTTP
response line is sent, followed by \emph{Server} and \emph{Date}
headers. The values for these two headers are picked up from the
\method{version_string()} and \method{date_time_string()} methods,
respectively.
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{send_header}{keyword, value}
+\begin{methoddesc}{send_header}{keyword, value}
Writes a specific MIME header to the output stream. \var{keyword}
should specify the header keyword, with \var{value} specifying
its value.
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{end_headers}{}
+\begin{methoddesc}{end_headers}{}
Sends a blank line, indicating the end of the MIME headers in
the response.
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{log_request}{\optional{code\optional{, size}}}
+\begin{methoddesc}{log_request}{\optional{code\optional{, size}}}
Logs an accepted (successful) request. \var{code} should specify
the numeric HTTP code associated with the response. If a size of
the response is available, then it should be passed as the
\var{size} parameter.
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{log_error}{...}
+\begin{methoddesc}{log_error}{...}
Logs an error when a request cannot be fulfilled. By default,
it passes the message to \method{log_message()}, so it takes the
same arguments (\var{format} and additional values).
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{log_message}{format, ...}
+\begin{methoddesc}{log_message}{format, ...}
Logs an arbitrary message to \code{sys.stderr}. This is typically
overridden to create custom error logging mechanisms. The
\var{format} argument is a standard printf-style format string,
where the additional arguments to \method{log_message()} are applied
as inputs to the formatting. The client address and current date
and time are prefixed to every message logged.
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{version_string}{}
+\begin{methoddesc}{version_string}{}
Returns the server software's version string. This is a combination
of the \member{server_version} and \member{sys_version} class variables.
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{date_time_string}{}
+\begin{methoddesc}{date_time_string}{}
Returns the current date and time, formatted for a message header.
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{log_data_time_string}{}
+\begin{methoddesc}{log_data_time_string}{}
Returns the current date and time, formatted for logging.
-\end{funcdesc}
+\end{methoddesc}
-\begin{funcdesc}{address_string}{}
+\begin{methoddesc}{address_string}{}
Returns the client address, formatted for logging. A name lookup
is performed on the client's IP address.
