% The \Lpack{memoir} class is designed for typesetting
% general books such as novels, biographies, histories, 
% and so on, although as it supports all the functionality of the 
% standard \Lpack{book} class it can also be used for technical writing.
% It provides more functions than the standard class as well as 
% presenting a more friendly interface for the book designer.
% It can also simulate the typesetting style of the standard \Lpack{article}
% class.
%
%    Because of its newness not all packages work well with \Lpack{memoir}.
% Also, as more users beat on it, subtle flaws are discovered in \Lpack{memoir}
% itself. Patching code is supplied to resolve known problems.
%
%    Code is also provided for new functionality that will later be 
% folded into the class code.

% \section{Introduction}
%
% This document provides the commented source for packages that patch
% the LaTeX \Lpack{memoir} class~\cite{MEMOIR}. 
% This class is designed for typesetting
% general books such as novels, biographies, histories, 
% and so on. It has all the functionality of the standard \Lpack{book}
% class and, as well as providing some extra functions, also provides
% a more friendly interface for the document designer. As it can encompass
% everything that the \Lpack{book} class provides it may also be used
% for technical writing.
%
%
%    Section~\ref{sec:docstrip} describes some
% administrative elements and code for general use later in the 
% specification.
% The macros forming the package files are defined in section~\ref{sec:hyper}
% and in section~\ref{sec:class} onwards.
% 
% This manual is typeset according to the conventions of the
% \LaTeX{} \textsc{docstrip} utility which enables the automatic
% extraction of the \LaTeX{} macro source files~\cite{GOOSSENS94}.
%
%
% \section{A driver for this document} \label{sec:docstrip}
%
% The next series of code contains the documentation driver file for
% \LaTeX, i.e., the file that will produce the documentation you are
% currently reading. This will be extracted from this file by the 
% \textsc{docstrip} program.

% \section{Patches for hyperref and friends} \label{sec:hyper}

% that contain anything out of the
% ordinary.

%  \item Other fixes as and when

% 
% The nameref package changes \cs{@sect} and \cs{label} so we bring
% back the memoir stuff. We have earlier been using
% \verb?\AtBeginDocument? plus \verb?\@ifpackageloaded{nameref}? to
% add our changes to \Lpack{nameref}. But this is not a good solution,
% as \Lpack{hyperref} can delay \Lpack{nameref} loading using
% \verb?\AtBeginDocument{\usepackage{nameref}}? \emph{and} add thiis
% \emph{after} \Lpack{memhfixc} is loaded. A better solution is to use
% \verb?\AtEndPackage?, then it does not matter how far after
% \Lpack{memhfixc} \Lpack{nameref} is loaded.
