+
+The bundle has the status of author maintained.
+
+The main purpose of this bundle is to exploit the possibility of running
+an index formatting program from within a document typesetting task (tested
+with the engines pdftex, xetex, and luatex in their incarnation set up to
+process the LaTeX markup)at the \printindex level, so that one or more indices
+can be typeset in such a way that they are always synchronous with the
+document they belong to.
+
+With the TeXlive 2010 release the makeindex program can be safely run within
+a TeX run; with previous distributions the shell escape feature must be
+explicity enabled. With the 2010 distribution the makeindex program is directly
+accessible.
+
+This bundle is compatible with most existing classes; at present it is
+incompatible only with the memoir class, because of its special way of
+handling multiple indices.

+% \begin{abstract}
+% This package exploits the |\write18| facility of modern \TeX\ system
+% distributions that allows to run system commands while typesetting a
+% document written with the \LaTeX{} mark up.  By so doing, the index
+% or indices, that are usually typeset at the very end of the
+% document, are possibly split and sorted so as to include them in the
+% document itself. This process has some minor limitations: it's
+% impossible to start an index before all other pages have been
+% ejected and to have the automatic run of the index sorting program.
+% \end{abstract}
+%
+% \section{Introduction}
+% It's been some years now that the typesetting engine of the \TeX\
+% system is just \prog{pdftex}; the original Knuthian \prog{tex} is
+% still corrected by D.\,E.~Knuth himself, but is frozen, according to
+% his will; it is still distributed by every \TeX\ distribution, but
+% in practice only \prog{pdftex} is used as the interpreter of every
+% macro package and the true typesetter engine. The latter is updated
+% with the original \prog{tex} corrections, but it is the only one
+% that the \LaTeX3 Team maintains and upgrades.
+%
+% This program \prog{pdftex} was originally born with the facility of
+% producing either a pdf output file, as its name suggests, or a dvi
+% file. Since then it has been enriched with many upgrades, also with
+% regard to the evolution of the PDF language itself. It also
+% incorporates the extensions of \eTeX\ and has the ability to open a
+% shell so as to call system commands with their arguments.
+% 
+% This facility, since the \TeX~Live 2010 distribution, is official,
+% but is sort of restricted, in the sense that the \TeX\ system
+% configuration file contains a list of ``safe'' system commands that
+% can be run by \prog{pdftex}; presently the only program relevant for
+% this package is \prog{makeindex}. This precaution is necessary in
+% order to avoid running malicious code. Other programs can be run,
+% though, but it's necessary to expressly tell \prog{pdftex} that it
+% can do so; this authorisation is given by means of a suitable
+% program option, as explained below.
+%
+% This package will exploit this facility in order to run a perl
+% script that is capable of splitting a raw index file into different
+% chunks and to run the \prog{makeindex} \TeX\ system program so as to
+% sort and format the index entries according to a specified index
+% style file. Once the shell is terminated, the \prog{pdftex} program
+% resumes its work and possibly prints the various formatted indices
+% produced in previous step. In this way the document indices are
+% always synchronous with their document and no further \prog{pdftex}
+% runs are necessary.
+%
+% In order to reach this goal, it necessary to enable the
+% \prog{pdftex} engine to run the so-called |\write18| facility;
+% depending on the distribution and the shell editor that is being
+% used to work on a specific document, it is necessary to add
+% \texttt{-shell-escape} (or \texttt{-\/-enable-write18} for MiK\TeX)
+% to the command with which \prog{pdftex} is launched, possibly by the
+% shell editor. If Lua\LaTeX{} is used, it's necessary to specify the
+% \texttt{-shell-escape} command line option.
+%
+%\section{Package usage}
+% This package is invoked as usual by means of a \cs{usepackage} command:
+% \begin{flushleft}
+% \cs{usepackage}\oarg{options}\texttt{\{imakeidx\}}
+% \end{flushleft}
+%
+% The available \meta{options} consist in a comma separated list of
+% the following options:
+% \begin{description}\def\Item[#1]{\item[\normalfont\ttfamily#1]}
+% \Item[makeindex] in order to use the \prog{makeindex} sorting an
+% formatting engine; this option is the default and is mutually
+% exclusive with the next option.
+% \Item[xindy] in order to use the \prog{xindy} sorting and formatting
+% engine; \texttt{texindy} is an alias for \texttt{xindy} and actually
+% it's the script \prog{texindy} which is called by this package.
+% \Item[noautomatic] disables the automatic splitting and running of
+% the system programs; this option might be used to save time when one
+% knows for sure that the index files are already OK and do not need
+% to be refreshed. Actually the time spent in splitting, sorting and
+% formatting is so short that this option might be useful only when
+% very lengthy indices are being processed.
+% \Item[nonewpage] inhibits the new page command to be issued when
+% using an article type document class and multiple indices are being
+% typeset. We don't see why someone would use multiple indices in an
+% article (except possibly for package documentations, which usually
+% provide a macro index and a list of changes).
+% \Item[quiet] suppresses all messages about manual index
+% processing.
+% \Item[original] uses the class provided \texttt{theindex}
+% environment for typesetting the indices; it is implicitly set if the
+% document class option \texttt{twocolumn} has been specified.
+% \Item[splitindex] calls the \prog{splitindex} script by Markus Kohm,
+% which is included in every \TeX~Live distribution since 2009. With
+% this option all index entries, which are written in one raw file,
+% are successively split into all the requested index files; in this
+% way there is virtually no limit on the number of indices that is
+% possible to create for a particular document.
+% \end{description}
+%
+% The last described option deserves an explanation. \LaTeX{} can
+% write on a limited number of files during a run, and some of these
+% \emph{output streams} are already reserved (among these: aux file,
+% table of contents, list of figures, list of tables). When more than
+% one index is produced, there's the risk to run off the number of
+% writable files, because normally \pack{imakeidx} reserves an output
+% stream for each index.  So the \texttt{splitindex} option comes to
+% rescue: with it only \emph{one} index file is written. At the
+% first \cs{printindex} command, the program \prog{splitindex} is
+% called; it splits the large index file into as many parts as the
+% number of requested indices; after this, \prog{makeindex} (or
+% \prog{xindy}) can do its job. In this way only one output stream is
+% needed during the \LaTeX{} run.
+%
+% When should you apply this option, then? With one index it's
+% useless, you should begin to consider it for two or more indices and
+% definitely use it if you get the error
+% \begin{verbatim}
+% ! No room for a new \write
+% \end{verbatim}
+% Apart from this case, with or without it the results are the
+% same. See section~\ref{sec:wrong} to see what files are written
+% during the \LaTeX{} run with or without the option.
+%
+% \section{Specific package commands}
+% \addtocontents{toc}{\protect\columnbreak\protect\vspace*{.4ex}}
+% As it is customary when just one index is produced, the standard
+% \LaTeX\ facilities, i.e.\ the commands \cs{makeindex}, \cs{index},
+% and \cs{printindex} must be used. This package redefines them so as
+% to produce multiple indices and defines some others. The first three
+% of the following commands may be used only in the preamble.
+% \begin{description}\def\Item[#1]{\item[\normalfont\ttfamily\cs{#1}]}
+% \Item[makeindex] with the syntax:\\[1ex]
+% \cs{makeindex}\oarg{key-values}\\[1ex]
+% where \meta{key-values} is a comma separated list of key-value
+% assignments of the form: \texttt{key=value}; the available
+% keys are the following:
+% \begin{description}\def\Item[#1]{\item[\normalfont\sffamily\textsl{#1}]}
+% \Item[name] is the symbolic name for an index; if this key is not
+% specified, it defaults to the value of the \cs{jobname} control
+% sequence, in other words the name of the current main \texttt{.tex}
+% program file, i.e., the file that |\input|s and/or |\include|s all
+% the files of the complete document. This symbolic name is necessary
+% only when doing multiple indices and is used with the \cs{index}
+% command to point to the right index.\\*
+% Example: \texttt{name=nameidx}
+% \Item[title] is the title that is typeset at the beginning of the
+% specific index; if not specified, the \cs{indexname} value is
+% used.\\* Example: \texttt{title=Index of names}
+% \Item[program] is the name of the system program that is used to
+% sort and format an index; valid choices are \prog{makeindex},
+% \prog{xindy}, or \prog{texindy}. If not specified the program
+% specified among the package options is used. If no option is
+% specified, \prog{makeindex} is used. In order to use \prog{xindy},
+% it's necessary to call \progpdflatex{} with the shell escape
+% command line option.\\* Example: \texttt{program=xindy}
+% \Item[options] is the list of options to be passed to the sorting
+% and formatting program; this list is a balanced text of program
+% options, separated with the syntax required by the sorting and
+% formatting program. For example, in order to use a different
+% \prog{makeindex} sorting and formatting style \pack{mystyle.ist} and
+% avoiding any message in the screen output write \texttt{options=-s
+% mystyle}
+% \Item[noautomatic] is a boolean key that defaults to \texttt{false};
+% you can set it to \texttt{true} by simply listing its key in the
+% key-value list, without necessarily specifying the \texttt{=true}
+% part. If specified the index sorting program won't be called during
+% the \prog{pdftex} run for this particular index.
+% \Item[intoc] is a boolean variable that defaults to \texttt{false};
+% if you want to set it \texttt{true} you must simply list this key in
+% the key-value list, with no need of specifying the \texttt{=true}
+% part. By setting this key to \texttt{true} an entry for this
+% particular index is put in the table of contents.
+% \Item[columns] accepts an integer representing the number of columns
+% in the index; this is silently ignored if the \texttt{original} or
+% the \texttt{twocolumn} options are set; the number can even
+% be~$1$.\\* Example: \texttt{columns=3}
+% \Item[columnsep] accepts a dimension representing the separation
+% between index columns; the default is $35$\,pt as in the standard
+% classes.\\* Example: \texttt{columnsep=15pt}
+% \Item[columnseprule] is boolean; if it is set, a rule will appear
+% between the index columns.
+% \end{description}
+% \Item[indexsetup] with the syntax:\\[1ex]
+% \cs{indexsetup}\oarg{key-values}\\[1ex]
+% where again \meta{key-values} is a comma separated list of key-value
+% assignments; the available keys are:
+% \begin{description}\def\Item[#1]{\item[\normalfont\sffamily\textsl{#1}]}
+% \Item[level] which takes as value a sectioning command such as
+% \cs{chapter} or \cs{chapter*}. Actually any command with an argument
+% will do and will receive the index title as its argument. The
+% default is \cs{chapter*} or, if the class doesn't provide chapters,
+% \cs{section*}.
+% \Item[toclevel] which takes as value a sectioning command
+% \emph{name} such as \texttt{section} to indicate the level at which
+% we want the indices appear in the table of contents.
+% \Item[noclearpage] is a boolean option; when set, no \cs{clearpage}
+% will be issued between indices. You might want to set it in order to
+% have a `chapter of indices'; in this case you are responsible for
+% setting the right value of the above keys. For example
+%\begin{verbatim}
+% \indexsetup{level=\section*,toclevel=section,noclearpage}
+% ...
+% \chapter*{Indices}
+% \printindex
+% \printindex[names]
+% \printindex[objects]
+%\end{verbatim}
+% \Item[firstpagestyle] which takes as value a page style, default
+% \texttt{plain}. You might want to set it to \texttt{empty} or some
+% other page style defined by the class or by yourselves.
+% \Item[headers] which takes as value the left and right marks. You
+% might want to use this for disabling automatic uppercasing, by
+% saying |headers={\indexname}{\indexname}|; notice that this value
+% should always be a pair of braced texts.
+% \Item[othercode] which takes as value arbitrary \TeX{} code that
+% will be executed at the beginning of index entries typesetting. For
+% example you might want to change here the setting of \cs{parskip}.
+% \end{description}
+% \Item[splitindexoptions] must have as its argument the command line
+% option to \prog{splitindex}; this might be necessary on some
+% systems. The default is |-m ""|, because we want it only for
+% splitting the large index file into its components which are later
+% processed by this package.
+% \Item[index] with the syntax:\\[1ex]
+% \cs{index}\oarg{name}\marg{entry}\\[1ex]
+% inserts \meta{entry} into the raw index file; upon splitting it in
+% different files, this particular entry is listed in the specific
+% index file with name \meta{name}; if no name is specified, this
+% \meta{entry} is added to the default index with name
+% \cs{jobname}. The \meta{entry} should be written according to the
+% particular syntax of the sorting and formatting program.
+% \Item[indexprologue] with the syntax:\\*[1ex]
+% \cs{indexprologue}\oarg{spacing}\marg{text}\\[1ex]
+% is used to define some text to go between the index header and the
+% entries; the \meta{spacing} should be a vertical space command such
+% as |\vspace{36pt}| (default is \cs{bigskip}), controlling the
+% spacing between the prologue and the index proper. The command
+% affects only the next index produced by \cs{printindex}.
+% \Item[printindex] with the syntax:\\*[1ex]
+% \cs{printindex}\oarg{name}\\[1ex]
+% is used to typeset the particular index named \meta{name}; if no
+% optional argument is specified, the default index with name
+% \cs{jobname.ind} is typeset.  Actually this command activates all
+% the mechanism of closing the output to the raw index file, shelling
+% out, possibly calling the \prog{splitindex} script in order to
+% divide the single raw file generated by \progpdflatex{} into
+% distinct raw files according to the default or specified
+% \meta{name}s for each index, calling the sorting and
+% formatting program on each of these split raw files (unless
+% inhibited by a \Kvalue{noautomatic} option; in which case a warning
+% is issued in order to remember the typesetter that this particular
+% index has not been processed), producing the sorted and formatted
+% \texttt{.ind} files, and eventually inputs and typesets these
+% formatted files. \ Deep breath.
+% \end{description}
+%
+% Let's see an example. The sequence of commands
+%\begin{verbatim}
+% ...
+% \usepackage{imakeidx}
+% ...
+% \makeindex[title=Concept index]
+% \makeindex[name=persons,title=Index of names,columns=3]
+% ...
+% \begin{document}
+% ...
+% And this is the end of the story.
+%
+% \printindex
+%
+% \indexprologue{\small In this index you'll find only
+%   famous people's names}
+% \printindex[persons]
+% \end{document}
+%\end{verbatim}
+% will produce two indices. Entries for the first one must be typed as
+% |\index{gnu}|, while entries for the second are of the form
+% |\index[persons]{Lamport, Leslie}|. The prologue will be printed
+% (full line) only in the ``Index of names'', which will be typeset in
+% three columns.
+%
+% When the \texttt{original} option is set, maybe implicitly because
+% of \texttt{twocolumn}, \cs{indexsetup} and the keys
+% \Kvalue{columns}, \Kvalue{columnsep} and \Kvalue{columnseprule} for
+% \cs{makeindex} have no effect.
+%
+% \section{If something goes wrong}\label{sec:wrong}
+% Since \pack{imakeidx} relies on good cooperation between package
+% options and command line options for the \LaTeX{} run, in some cases
+% it may happen that the indices are not correctly built or built at
+% all.
+%
+% If you use only \prog{makeindex} and \TeX~Live 2010 or later, then
+% you shouldn't need anything special, since \prog{makeindex} is among
+% the safe programs allowed to be called during a \LaTeX{} run, be it
+% \prog{latex}, \prog{pdflatex} or \prog{xelatex} (or even
+% \prog{lualatex}, at present with some glitches). When the options
+% \texttt{splitindex}, \texttt{xindy} or \texttt{texindy} are
+% specified (globally or locally), the \LaTeX{} run should be called
+% with \texttt{-shell-escape} (which is \texttt{--enable-write18} for
+% MiK\TeX) or the \texttt{noautomatic} option should be specified when
+% loading \pack{imakeidx}.
+% 
+% Let's look at a couple of examples. In both we suppose that the
+% document \texttt{mybook.tex} defines two indices through
+%\begin{verbatim}
+% \makeindex[...]
+% \makeindex[name=secondary,...]
+%\end{verbatim}
+% where |...| denotes possible options excluding \texttt{name}.
+%
+% First of all we examine the case when \pack{imakeidx} is called
+% \emph{without} \texttt{splitindex}. Two files called
+% \texttt{mybook.idx} and \texttt{secondary.idx} will be written
+% during the \LaTeX{} run. At the corresponding \cs{printindex}
+% command, \prog{makeindex} will act on each of them producing the files
+% \texttt{mybook.ind}, \texttt{mybook.ilg}, \texttt{secondary.ind} and
+% \texttt{secondary.ilg}. The \texttt{.ind} files contain the relevant
+% \texttt{theindex} environment with alphabetized entries, while in
+% the \texttt{.ilg} files \prog{makeindex} will write its log. You can
+% check in \texttt{mybook.log} whether the \prog{makeindex} run has
+% been executed by searching for a line
+%\begin{verbatim}
+% runsystem(makeindex <...>)...executed
+%\end{verbatim}
+% where |<...>| stands for the rest of the command line in the
+% particular case. If this line is not present, then \prog{makeindex}
+% has not been called; this happens when you didn't specify the shell
+% escape command line option for the \LaTeX{} run or if you set the
+% \texttt{noautomatic} option for the index.
+%
+% When using \prog{splitindex}, the situation is different. During the
+% \LaTeX{} run, only a large index file called \texttt{mybook.idx} file
+% gets written; the first \cs{printindex} command will call
+% \prog{splitindex} (shell escape \emph{must} be active), which will
+% produce the two partial index files \texttt{mybook-mybook.idx} and
+% \texttt{mybook-secondary.idx}. These two files will be processed by
+% \prog{makeindex} producing the four files
+% \texttt{mybook-mybook.ind}, \texttt{mybook-mybook.ilg},
+% \texttt{mybook-secondary.ind} and \texttt{mybook-secondary.ilg}.
+% The line
+%\begin{verbatim}
+% runsystem(splitindex <...>)...executed
+%\end{verbatim}
+% in \texttt{mybook.log} will tell that the splitting has been done
+% (see later on if this doesn't seem true). In table~\ref{tab:files} you
+% can see what files are produced when the first two lines are in the
+% preamble.

+% \end{tabular}\endgroup
+% \caption{Files written during a \LaTeX{} run}\label{tab:files}
+% \end{table}
+%
+% Everything is the same when using \prog{texindy} for alphabetizing,
+% except that, by default, it doesn't write \texttt{.ilg} files. If
+% you want them, add |options=-t|\meta{name}|.ilg| to the relevant
+% \cs{makeindex} command, in our example it should be
+%\begin{verbatim}
+% \makeindex[...,options=-t mybook.ilg]
+% \makeindex[name=secondary,...,options=-t secondary.ilg]
+%\end{verbatim}
+% The name of the \texttt{.ilg} file \emph{must} be specified.
+% Remember, though, that \prog{xindy} \texttt{.ilg} files may turn out
+% to be very large.
+%
+% When something different from expected appears to take place, check
+% also the time stamps of the produced files; if they are older than
+% \texttt{mybook.log}, it means that they have not been written in the
+% last run. The most common case is that you forgot to activate the shell
+% escape feature (which is not necessary with \TeX~Live 2010 or later,
+% provided you use only \prog{makeindex}).
+%
+% Another cause of malfunction might be a wrong option passed to
+% \prog{makeindex}, \prog{texindy} or \prog{splitindex}. For example,
+% if you specify a style option for \prog{makeindex} such as
+% |options=-s mystyle.ist| and the style file is missing or its name
+% is mistyped, the run of \prog{makeindex} will result in
+% \texttt{mybook.log}, but it will be aborted and the \TeX{} program
+% has no control over this process. In this case the \texttt{.ilg} and
+% \texttt{.ind} files will not be produced and you can spot the
+% problem by checking the time stamps. On some systems a message such as
+%\begin{verbatim}
+% Index file mystyle.ist not found
+% Usage: makeindex [-ilqrcgLT] [-s sty] [-o ind] [-t log] [-p num]
+%\end{verbatim}
+% may appear on the screen, but often this window gets closed before
+% you realize you have a problem. The time stamp is the best clue to
+% detect such problems.
+%
+% Shell hackers may be able to redirect the \texttt{stderr} stream to
+% a file, but this requires skills that can't be explained here,
+% because they require tens of different tricks, depending on what
+% method is used to start a \LaTeX{} run. From the command line,
+% assuming \prog{bash}, it would be something like
+%\begin{verbatim}
+% pdflatex -shell-escape mybook.tex 2>latex-errors
+%\end{verbatim}
+% If shell hackers know a way to access the exit status of the called
+% program, we'd be glad to implement a supplementary check.
+%
+% \section{Hints}
+% Actually this package reaches two goals: (\textit{a})~it typesets
+% the indices of a specific document in just one run, and
+% (\textit{b})~it lets the author\slash typesetter produce
+% documents with multiple indices.
+%
+% If you redefine yourself the \texttt{theindex} environment, please
+% remember not to number the chapter or section that introduces the
+% index if you ask for the \Kvalue{intoc} option; either use the
+% commands \cs{chapter*} or the \cs{section*} respectively and the
+% \Kvalue{intoc} option or don't use this option and redefine your
+% \texttt{theindex} environment with numbered chapter or section
+% commands, that will put the index titles directly into the table of
+% contents. You may use the \pack{idxlayout} package by Thomas Titz,
+% which offers many functions for index typesetting customization and
+% is compatible with our package; remember to load \pack{idxlayout}
+% after \pack{imakeidx}. This package has a similar function to our
+% \cs{indexprologue}, called \cs{setindexprenote}; however
+% \pack{idxlayout} doesn't reset the index prologue, which must be
+% declared anew or disabled with \cs{noindexprenote} before the next
+% \cs{printindex} command.
+%
+% If by chance you get double entries into the table of contents,
+% eliminate the \Kvalue{intoc} option from your calls; your class and
+% packages are already taking care of it. The package \pack{tocbibind}
+% should be loaded with the \texttt{noindex} option, otherwise it
+% would interfere with our redefinition of \texttt{theindex}.
+%
+% If you redefine your \texttt{theindex} environment by means of other
+% packages, pay attention that these redefine a real \texttt{theindex}
+% environment with this very name; if they create an environment with
+% a different name, \pack{imakeidx} can't take care of the indices
+% production (in particular the \TeX\ system program \prog{makeindex}
+% creates a sorted and formatted \texttt{.ind} file that refers
+% explicitly to the \texttt{theindex} environment), and it can't take
+% care of the table of contents entry and of the position of the hyper
+% link anchor needed to navigate your document by means of hyper
+% links.
+%
+% Use freely the options and the key values in order to reach the
+% desired results, but you are advised to prepare in advance the
+% styles for composing the various indices in a proper way; for
+% example, if you use a titled style for the index, where the index
+% sections are distinguished with a bold face title or alphabetic
+% letter, you have to set up a \texttt{.ist} file, such as
+% \texttt{myindexstyle.ist}, made up like this:
+%\begin{verbatim}
+%	headings_flag 1
+%	heading_prefix   "\\par\\penalty-50\\textbf{"
+%	heading_suffix   "}\\\\\*\~\\\\\*"
+%	symhead_positive "Symbols"
+%	symhead_negative "symbols"
+%	numhead_positive "Numbers"
+%	numhead_negative "numbers"
+%	delim_0 ",\~"
+%\end{verbatim}
+% where the numeric and non alphabetic entries have different
+% titles. But, say, you are making also an index where the entries are
+% file names, and for some names only the extension is entered; the
+% extensions start with a dot, so the sorting program will sort these
+% names at the beginning of the sorted index file, but you won't like
+% to have
+% a title such as ``Symbols''; you probably prefer to have a title
+% such as ``Extensions''; therefore you have to prepare a different
+% index style file, such as this one:
+%\begin{verbatim}
+%	headings_flag 1
+%	heading_prefix   "\\par\\penalty-50\\textbf{"
+%	heading_suffix   "}\\\\\*\~\\\\\*"
+%	symhead_positive "Extensions"
+%	symhead_negative "extensions"
+%	numhead_positive "Numbers"
+%	numhead_negative "numbers"
+%	delim_0 ",\~"
+%\end{verbatim}
+%
+% This done, besides requiring the use of this package, you have to
+% declare the \cs{makeindex} command with the necessary options; pay a
+% particular attention to the options that involve the index symbolic
+% name, the index title, the index style, the fact that the index
+% titles shall appear in the table of contents, and if you are
+% preparing an e-book, you probably would like to hyper link both the
+% page numbers and the index titles to the proper locations.
+% \prog{pdflatex} will do everything for you but be careful not to
+% confuse it with illogical index entries.
+%
+% Especially with multiple indices it is important that you are
+% consistent in putting the right information in the right index and
+% with a consistent mark-up. Define yourself appropriate macros so
+% that, for example, personal names are consistently typeset, say, in
+% caps and small caps and are entered into a specific index; you may
+% even create one command to typeset the name in the document and
+% replicate the same name in the index.
+%
+% Of course there is no program that can decide at your place what and
+% where to index each piece of information; this is a task for
+% humans. Soooooo\dots

+% \section{Implementation}
+% The heading to the file is in common with the documentation file,
+% and has already been taken care of. But we require the
+% \pack{xkeyval} package, in order to handle the key-value lists.
+%
+% Notice that in order to create e specific name space such as to
+% avoid possible conflicts with other packages, all the commands
+% defined in this package are prefixed with the string \texttt{imki@}.
+%    \begin{macrocode}
+\RequirePackage{xkeyval}
+%    \end{macrocode}
+%
+% We define the various options and their defaults. After
+% \cs{ProcessOptions}, we set anyway the \texttt{original} option if
+% the document class has been given the \texttt{twocolumn} option,
+% which is incompatible with \pack{multicol}. We define also an
+% internal alias for |\immediate\write18|, a rudimentary check for the
+% typesetting engine and a macro for modifying the command line call
+% to \prog{splitindex}. Lua\TeX{} is recognized later by the
+% value~$255$ to the internal parameter \cs{imki@shellescape}.

+% ^^A A - incompatibilities and emulation
+%
+% While experimenting we found out that some classes or packages are
+% either incompatible with this one, or must be faked in order to
+% pretend they have been loaded.
+%
+% Unfortunately there is a serious incompatibility with the
+% \pack{memoir} class.  In facts \pack{memoir} puts all index entries
+% in the main \texttt{.aux} file and extracts them to the various raw
+% index files at |\end{document}| time. This means that no raw index
+% file output stream has been defined, and therefore this package
+% can't close it; moreover it can't typeset the indices before
+% |\end{document}| because they are not yet available. Therefore if
+% this one is the active class chosen for typesetting the whole
+% document, this package outputs an error message and exits.
+%    \begin{macrocode}
+\@ifclassloaded{memoir}{%
+  \PackageError{imakeidx}{Incompatible package won't be loaded}
+    {This package is incompatible with memoir, sorry}\endinput}{}
+%    \end{macrocode}
+% On the opposite we pretend that package \pack{makeidx} or package
+% \pack{multind} have been loaded, so that \pack{hyperref} can play
+% with their commands, that are substantially the same as those used
+% here. By so doing those packages are inhibited from being loaded
+% after this one.
+%    \begin{macrocode}
+\@namedef{ver@makeidx.sty}{3000/12/31}
+\@ifpackageloaded{multind}
+  {\PackageError{imakeidx}{Incompatible package `multind' loaded}
+    {This package is incompatible with multind, don't load both.%
+     \MessageBreak\@ehc}}
+  {\@namedef{ver@multind.sty}{3000/12/31}}
+%    \end{macrocode}
+% At the same time we redefine some commands defined by \pack{makeidx}
+% and we define the default English names for the \cs{see} and
+% \cs{seealso} commands. We use \cs{providecommand} so that, if
+% \pack{makeidx} has already been loaded, we do not redefine things
+% that have already been defined.
+%    \begin{macrocode}
+\providecommand*\see[2]{\emph{\seename} #1}
+\providecommand*\seealso[2]{\emph{\alsoname} #1}
+\providecommand*\seename{see}
+\providecommand*\alsoname{see also}
+%    \end{macrocode}
+%
+% ^^A C - \makeindex
+%
+% From here on, some commands are duplicated; this depends on the
+% fact that the behavior must be different when using \prog{splitindex} or
+% not. The memory occupied by the useless commands will be cleared at the 
+% end of package.
+%    \begin{macrocode}
+\providecommand*\makeindex{} % to use \renewcommand safely
+\renewcommand{\makeindex}[1][]{\imki@makeindex{#1}}
+% \@onlypreamble\makeindex % Already in latex.ltx
+%    \end{macrocode}
+% This package implementation of \cs{makeindex} sets default values
+% for the keys, then evaluates its argument (which is the optional
+% argument to \cs{makeindex}) and calls two other macros. After that
+% we have to reset the defaults.

+%
+% Command \cs{imki@startidx} defines the output stream(s); the macro
+% with suffix \texttt{split} is used when \Kvalue{splitindex} is not
+% enabled, the one with suffix \texttt{unique} is used otherwise.  In
+% the case of many indices, the symbolic name for an index named
+% `pippo' is \cs{pippo@idxfile} corresponding to the file
+% \texttt{pippo.idx}. When \Kvalue{splitindex} is enabled, the only
+% output stream is called \cs{@indexfile} as in standard \LaTeX,
+% corresponding to \cs{jobname.idx}.

+%
+% ^^A D - \index 
+%
+% Provide a default definition for \cs{index}; when a \cs{makeindex}
+% command is given and \LaTeX\ is writing on auxiliary files,
+% \cs{index} will be redefined, as seen before. When index files are
+% written, \cs{index} always calls \cs{@index}. Some code is borrowed
+% from \pack{memoir.cls}, but heavily modified. We want \cs{@wrindex}
+% to be defined with two arguments, so that \pack{hyperref} can hook
+% into it just like it does with the similar commands defined by the
+% old packages \pack{multind} and \pack{index}.
+%    \begin{macrocode}

+%
+% ^^A E - \printindex
+%
+% Compilation of the indices is disabled if \texttt{-shell-escape} has
+% not been given or the restricted mode is not active; in this case we
+% emit a warning. \XeTeX{} has \cs{shellescape} instead of
+% \cs{pdfshellescape}, so we take care of this (hoping that users or
+% packages don't define a \cs{shellescape} command). In any case we
+% define an internal version of this command. In the case of
+% \prog{luatex} we can't emit the proper messages and hope that Heiko
+% Oberdiek will update \pack{pdftexcmds}; for the moment we set
+% \cs{imki@shellescape} to~$1$. The conditional
+% \cs{ifKV@imki@noautomatic} is defined by \cs{define@boolkey} above.

+% Now we set up the \texttt{theindex} environment. If the

+% We now define the main macro that puts the specified index file into
+% the document and possibly orders to add the index title to the
+% table of contents. It is duplicated as usual. The argument |#1| is
+% the specific symbolic name of the index.  In particular if the
+% \Kvalue{intoc} option has been specified, the hook
+% \cs{imki@maybeaddtotoc} is defined in such a way that the relevant
+% information is added to the \texttt{toc} file. The
+% \cs{phantomsection} command is necessary when using \pack{hyperref};
+% here it is hidden as argument to \cs{@nameuse}, so it is equivalent
+% to \cs{relax} and does nothing if \pack{hyperref} has not been
+% loaded.
