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. +% \begin{table}[tp] +% \centering\begingroup\ttfamily +% \begin{tabular}{rll} +% \toprule +% \multicolumn{3}{c}{\ttfamily\cs{makeindex}\hphantom{[name=secondary]}}\\ +% \multicolumn{3}{c}{\ttfamily\cs{makeindex}[name=secondary]}\\ +% \midrule +% \addlinespace +% &\normalfont without \texttt{splitindex} & +% \normalfont with \texttt{splitindex} \\ +% \cmidrule(lr){2-2} \cmidrule(lr){3-3} +% \addlinespace +% \normalfont(at \cs{begin}\texttt{\{document\}})\\ +% \addlinespace +% &mybook.idx & mybook.idx \\ +% &secondary.idx \\ +% \addlinespace +% \normalfont(at \cs{printindex})\\ +% \addlinespace +% &mybook.ind & mybook-mybook.idx \\ +% &mybook.ilg & mybook-secondary.idx\\ +% &secondary.ind & mybook-mybook.ind\\ +% &secondary.ilg & mybook-mybook.ilg\\ +% & & mybook-secondary.ind \\ +% & & mybook-secondary.ilg \\ +% \bottomrule +% \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.

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.

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.
