0006 This manual was originally translated from LATEX.HLP v1.0a in the
0007 VMS Help Library.  The pre-translation version was written by
0008 George D. Greenwade of Sam Houston State University.  The
0009 LaTeX 2.09 version was written by Stephen Gilmore.  The
0010 LaTeX2e version was adapted from this by Torsten Martinsen.  Karl
0011 Berry made further updates and additions, and gratefully acknowledges
0012 using Hypertext Help with LaTeX, by Sheldon Green, and
0013 LaTeX Command Summary (for LaTeX 2.09) by
0014 L. Botway and C. Biemesderfer (published by the TeX Users
0015 Group as TeXniques number 10), as reference material.  We also
0016 gratefully acknowledge additional material appearing in

0130 <div class="example">
0131 <pre class="example">makeindex <var>filename</var>
0132 makeindex -s <var>style-file</var> <var>filename</var>
0133 makeindex <var>options</var> <var>filename0</var> ...
0134 </pre></div>
0135 
0136 <p>Sort, and otherwise process, the index information in the auxiliary file
0137 <var>filename</var>.  This is a command line program.  It takes one or more
0138 raw index files, <samp><var>filename</var>.idx</samp> files, and produces the
0139 actual index file, the <samp><var>filename</var>.ind</samp> file that is input by
0140 <code>\printindex</code> (see <a href="_005cprintindex.html#g_t_005cprintindex">\printindex</a>).

0143 <a name="index-index_002c-style-file"></a>
0144 <a name="index-makeindex_002c-style-file"></a>
0145 <p>The first form of the command suffices for many uses.  The second allows
0146 you to format the index by using an <em>index style file</em>, a
0147 <samp>.isty</samp> file.  The third form is the most general; see the full
0148 documentation on CTAN.
0149 </p>
0150 <p>This is a simple <samp>.isty</samp> file.
0151 </p>
0152 <div class="example">
0153 <pre class="example">% book.isty 
0154 %   $ makeindex -s book.isty -p odd book.idx
0155 % creates the index as book.ind, starting on an odd page.

0167 <p>The description here covers only some of the index formatting
0168 possibilities in <var>style-file</var>. For a full list see the documentation
0169 on CTAN.
0170 </p>
0171 <p>A style file consists of a list of pairs: <var>specifier</var> and
0172 <var>attribute</var>.  These can appear in the file in any order.  All of the
0173 <var>attributes</var> are strings, except where noted.  Strings are
0174 surrounded with double quotes, <code>&quot;</code>, and the maximum length of a
0175 string is 144 characters.  The <code>\n</code> is for a newline and <code>\t</code>
0176 is for a tab.  Backslashes are escaped with another backslash,
0177 <code>\\</code>.  If a line begins with a percent sign, <code>%</code>, then it is a
0178 comment.

0357 internationalization and can process indexes for documents marked up
0358 using LaTeX and a number of other languages. It is highly
0359 configurable, both in markup terms and in terms of the collating order
0360 of the text, as described in its documentation.
