% \section{Introduction}
%
% This package provides the facility to produce multiple indexes
% with \amslatex/ document classes (particularly \fn{amsbook} and
% the AMS author packages for books), superseding the built-in
% index facility which can accommodate only one index. This may
% in the future be incorporated as an option into the \amslatex/
% document classes.
%
% This package is based on \pkg{multind.sty} by F.W. Long.
%
% \StopEventually{}
%
% Standard file identification.
% \begin{macrocode}
\NeedsTeXFormat{LaTeX2e}[1995/06/01]
\ProvidesPackage{amsmidx}[2004/08/03 v2.01 multiple indexes for AMS classes]
% \end{macrocode}
%
% \section{User instructions}
%
% In the preamble, invoke \cn{makeindex} with a file name to provide
% as many indexes as desired:
%\begin{verbatim}
% \makeindex{filename-a}
% \makeindex{filename-b}
%\end{verbatim}
% This will initiate the creation of \fn{filename-a.idx} etc.
%
% In the body of the text, use the \cn{index} command with two
% arguments
%\begin{verbatim}
% \index{filename-a}{index term}
%\end{verbatim}
% as appropriate to populate the \fn{.idx} files.
%
% In the \cn{backmatter} segment of the driver file, insert the
% \cn{Printendex} command to print the indexes; the second argument
% gives the title to be printed at the top of the index:
%\begin{verbatim}
% \Printindex{filename-a}{First Index}
% \Printindex{filename-b}{Second Index}
%\end{verbatim}
%
% On the first pass, the \fn{.idx} files will be created. Process
% each \fn{.idx} file with \textit{MakeIndex} to generate an \fn{.ind}
% file, which will then be read in by \cn{Printindex}. Whenever any
% page references change, be sure to run \textit{MakeIndex} again,
% and process the entire job with \latex/ once more to get the correct
% page references in the indexes.
%
% To include a paragraph of comments below the index title, insert
% the text as an \cn{indexcomment} before the relevant \cn{Printindex}:
%\begin{verbatim}
% \indexcomment{Text of comments}
% \Printindex{...}{...}
%\end{verbatim}
% The \cn{indexcomment} text will be cleared after use.
%
%
% \section{Implementation}
%
% \begin{macro}{makeindex}
% Redefine \cn{makeindex} to create a new \fn{.idx} file with the
% name provided by argument |#1|.

\endgroup}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{index}
% Redefine \cn{index} to specify into which file/index the term is
% to be placed. Argument |#1| identifies the file, |#2| provides
% the text of the term to be indexed.

% \begin{macro}{printindex}
% \begin{macro}{Printindex}
% Redefine \cs{printindex} to specify the file to be included; provide
% an alternate command \cs{Printindex} that specifies both the file and
% the index title to be printed. Argument |#1| identifies the file,
% |#2| provides the title. Also modify some formatting commands to
% improve the appearance of index entries, especially long ones in
% the presence of three index levels.
