1 MAKEINDEX
 MAKEINDEX is a general purpose index processor.  It takes one or more
 raw  index  files  (normally  generated  by  a  formatter), sorts the
 entries, and produces the actual index file.  It is not dependent  on
 any  particular  format  of  raw  index  file, although the .IDX file
 generated by LaTeX is the default.  Up to three levels (0, 1, and  2)
 of  subitem  nesting  within  the same entry is supported.  The input
 format may be redefined in a style file so that raw index or glossary
 output  from  other formatters may be processed.  The style file also
 defines the style of output index file.  Unless specified  otherwise,
 the  file  name  base  of  the  first  input  file  (idx0) is used to
 determine other related input/output files.  The default  input  file
 type is .IDX.

 Format:

 MAKEINDEX [options] idx0 [idx1 idx2 ...]
2 Options
 MAKEINDEX is a Unix program, and therefore has a  Unix-style  command
 line.   Instead  of  qualifiers delimited with a slash (/), MAKEINDEX
 options are delimited with a hyphen.
3 -i
 Use stdin as the input file.  When this option is specified  and  the
 -o is not, output is written to stdout.
3 -l
 Use letter ordering.  Default is  word  ordering  (explained  in  the
 ORDERING section).
3 -q
 Quiet mode, send no messages to  stderr.   By  default  progress  and
 error  messages  are  sent  to stderr as well as the transcript file.
 The -q option disables the stderr messages.
3 -r
 Disable implicit page range formation.   By  default  three  or  more
 successive  pages  will be automatically abbreviated as a range (e.g.
 1--5).   The  -r  option  disables  it,  making  the  explicit  range
 operators the only way to create page ranges (see the SPECIAL EFFECTS
 section below).
3 -c
 Enable blank compression.  By default every blank counts in the index
 key.   The -c option ignores leading and trailing blanks and tabs and
 compresses intermediate ones to a single space.
3 -s sty
 Take sty as the style file.  There is no default for the  style  file
 name.  The environment variable INDEXSTYLE defines the path where the
 style file should be found.
3 -o ind
 Take ind as the output index file.  By default the file name base  of
 the  first  input  file  idx0 concatenated with the extension .ind is
 used as the output file name.
3 -t log
 Take log as the transcript file.  By default the file  name  base  of
 the  first  input  file  idx0 concatenated with the extension .ilg is
 used as the transcript file name.
3 -p no
 Set the starting page number of the output index file to be no.  This
 is  useful  when the index file is to be formatted separately.  Other
 than pure numbers, three special cases are allowed for no:  any, odd,
 and  even.   In  these  special  cases,  the  starting page number is
 determined by retrieving the last page number  from  the  source  log
 file.   The  source  log file name is determined by concatenating the
 file name base of the first raw index file (idx0) with the  extension
 .log.   The last source page is obtained by searching backward in the
 log file for the first instance of a number included in [...].  If  a
 page  number is missing or the log file is not found, no attempt will
 be made to set the starting page number.   The  meaning  of  each  of
 these cases follows.

          any       The starting page  is  the  last  source
                    page number plus 1.

          odd       The starting page is the first odd  page
                    following the last source page number.

          even      The starting page is the first even page
                    following the last source page number.
2 Style_file
 The style file format is very simple.  It is a  list  of  <specifier,
 attribute>  pairs.   There  are  two  types  of specifiers (input and
 output).  The pairs don't have to obey any particular  order  in  the
 file.   A  line lead by `%' is a comment.  The following is a list of
 all the specifiers and their respective arguments where  <string>  is
 an  arbitrary  string delimited by double quotes ("..."), <char> is a
 single letter embraced by single quotes ('...'), and  <number>  is  a
 nonnegative  integer.   The  maximum  length  of  a  <string> is 144.
 Notice that a backslash must be escaped (by an  extra  backslash)  in
 the  string quotation.  Anything not specified in the style file will
 be assigned a default value, which is shown at the rightmost  column.
 This  file can reside anywhere in the path defined by the environment
 variable INDEXSTYLE.
3 Input_Style_Specifiers
4 keyword <string>

   "\\indexentry"

 This  is  the  command  which tells MakeIndex that its argument is an
 index entry.
4 arg_open <char>              

   '{'

 This is the opening delimiter for the index entry argument.
4 arg_close <char>

   '}'

 This is the closing delimiter for the index entry argument.
4 range_open <char>

   '('

 The  opening  delimiter  indicating the beginning of an explicit page
 range.
4 range_close <char>        

   ')'

 The closing delimiter indicating the end of an explicit page range.
4 level <char>

   '!'

 The delimiter which denotes a new level of subitem.
4 actual <char>
   '@'

 The  symbol which  indicates  that the next entry is to appear in the
 actual index file.
4 encap <char>

   '|'

 The symbol which indicates  that the rest of the argument  list is to
 be used as the encapsulating command for the page number.
4 quote <char>

   '"'
4 escape <char>
   '\\'

 The symbol which escapes the next letter, unless its preceding letter
 is escape.  In other words, quote is used to escape the letter  which
 immediately follows it.  But if it is preceded by escape, it does not
 escape anything.

 Notice that the two symbols must be distinct.
3 Output_Style_Specifiers
4 preamble <string>            

   "\\begin{theindex}\n"

 The preamble of actual index file.
4 postamble <string>

   "\n\n\\end{theindex}\n"

 The postamble of actual index file.
4 setpage_prefix <string>

   "\n  \\setcounter{page}{"

 The prefix of the command which sets the starting page number.
4 setpage_suffix <string>

   "}\n"

 The suffix of the command which sets the starting page number.
4 group_skip <string>

   "\n\n  \\indexsapce\n"

 The vertical space to be inserted before a new group begins.
4 lethead_prefix <string>

   ""

 The header prefix to be inserted before a new letter begins.
4 lethead_suffix <string>

   ""

 The header suffix to be inserted before a new letter begins.
4 lethead_flag <string>        

   0

 The  flag  indicating the  condition  of inserting new letter header.
 Default  is  0, which  means  no  header.   Positive  means insert an 
 uppercase letter between prefix and suffix.   Negative means insert a
 lowercase letter.
4 item_0 <string>

   "\n  \\item "

 The command to be inserted between two primary (level 0) items.
4 item_1 <string>

   "\n     \\subitem "

 The command to be inserted between two secondary (level 1) items.
4 item_2 <string>

   "\n       \\subsubitem "

 The command to be inserted between two level 2 items.
4 item_01 <string>
   "\n    \\subitem "

 The command to be inserted between a level 0 item and a level 1 item.
4 item_x1 <string>
   "\n    \\subitem "

 The command to be inserted between a level 0 item and a level 1 item.
 The difference  between  this and  previous  is that in this case the

 number.  Default is a comma followed by a blank.
4 delim_2 <string>

   ", "

 The delimiter to be inserted between a level 2 key and its first page
 number.  Default is a comma followed by a blank.
4 delim_n <string>

   ", "

 The delimiter  to  be inserted between  two page numbers for the same
 key in any level.  Default is a comma followed by a blank.
4 delim_r <string>

   "--"

   "\t\t"

 The space to be inserted in front of a wrapped line.   Default is two
 tabs.
4 indent_length <number>

   16

 The length of indent_space.   In the  default  case this is 16 (for 2
 tabs).
2 Example
 The following example shows  a  style  file  called  book.isty  which
 defines  a  stand-alone index for a book.  By stand-alone, we mean it
 can be formatted independent of the main source.

                preamble
                "\\documentstyle[12pt]{book}
                \\begin{document}
                \\begin{theindex}
                {\\small\n"

                postamble
                "\n\n}
                \\end{theindex}
                \\end{document}\n"

 Suppose a particular book style requires the index (as  well  as  any
 chapters) to start from an odd page number.  Given FOO.IDX as the raw
 index file, the following command line  produces  an  index  in  file
 FOO-.IND.

 MAKEINDEX  -s book.isty  -o foo-.ind  -p odd  foo

 The reason to  use  a  non-default  output  file  name  is  to  avoid
 clobbering  the  source  output  (presumably  foo.dvi) because if the
 index is in file foo.ind, its output will also be  in  foo.dvi  as  a
 result of separate formatting using .  In the example the index is in
 foo-.ind, its output will be  in  foo-.dvi  and  thus  introduces  no
 confusion.
2 Ordering
 By default makeindex assumes word ordering.  The -l option  turns  it
 into  letter  ordering.   The  only  difference is whether a blank is
 treated as an effective letter or not.  In  word  ordering,  a  blank
 precedes  any  letter in the alphabet, whereas in letter ordering, it
 doesn't count at all.  This is  best  illustrated  by  the  following
 example:

           word order               letter order
           sea lion                 seal
           seal                sea lion

 Numbers are sorted in numeric order.  For instance,

           9 (nine),  123
           10 (ten), see Derek, Bo

 Letters are first sorted  with  uppercase  and  lowercase  considered
 identical; then, within identical words the uppercase letter precedes
 its lowercase counterpart.

 Patterns lead by a special  symbol  precede  numbers,  which  precede
 patterns lead by a letter.  The symbol here refers to anything not in
 the union of digits and English alphabet.  This includes those  which
 follow  'z'  in the ASCII chart.  As a special case, anything started
 with a digit but mixed with non-digits is considered a symbol-leading
 pattern instead of a number.
2 Special_effects
 In the normal case entries such as

           \indexentry{alpha}{1}
           \indexentry{alpha!beta}{3}
           \indexentry{alpha!beta!gamma}{10}

 in the raw index file will be converted to

           \item alpha, 1
             \subitem beta, 3
               \subsubitem gamma, 10

 in the output index file by makeindex.  Notice that the level  symbol
 (`!') is used to delimit levels of nesting.

 It is possible to make an item appear in a designated form  by  using
 the actual (`@') operator.  For instance,

           \indexentry{alpha@{\it alpha\/}}{1}

 will become

           \item {\it alpha\/}  1

 after the conversion.  The idea is that the pattern preceding `@'  is
 used  as  sort key, whereas the one following it is put in the actual
 result.  However, the same key with and without the actual  part  are
 regarded as distinct entries.

 It is also possible to encapsulate a page number  with  a  designated
 command  using the encap (`|') operator.  For example, in the default
 case,

           \indexentry{alpha|bold}{1}

 will be converted to

           \item alpha \bold{1}

 where \bold{n} will  expand  to  {\bf  n}.   This  allows  the  encap
 operator  to  be  used  to  set  pages  in  different  fonts, thereby
 conveying  more  information  about  whatever  being  indexed.    For
 instance,  given  the  same key the page where its definition appears
 can be in one font while where its primary example is given can be in
 another,  with other ordinary appearances in a third.  Notice that in
 this example,  the  three  output  attributes  associated  with  page
 encapsulation  encap_prefix, encap_infix, and encap_suffix correspond
 respectively to backslash, left brace, and right brace.  If  this  is
 to  be  formatted  by  languages  other  than , they would be defined
 differently.

 By the same token, the encap operator  can  be  used  to  make  cross
 references in the index.  For instance,

           \indexentry{alpha|see{beta}}{1}

 will become

           \item alpha \see{beta}{1}

 in the output index file after the conversion, where

           \see{beta}{1}

 will expand to

           {\it see\/} beta

 Notice  that  in  a  cross  reference  like  this  the  page   number
 disappears.   Therefore, where to insert such a command in the source
 is immaterial.

 A  pair  of  encap  concatenated  with  range_open  (`|(')  and  with
 range_close (`|)') creates an explicit page range.  That is,

           \indexentry{alpha|(}{1}
           \indexentry{alpha|)}{5}

 will become

           \item alpha, 1--5

 Intermediate pages indexed by the same key will be  merged  into  the
 range  implicitly.   This is especially useful when an entire section
 about a particular subject is to be indexed, in which case  only  the
 range  opening  and  closing  operators  need  to  be inserted at the
 beginning and end of the section, respectively.

 This explicit page range formation can also include an extra  command
 to set the page range in a designated font.  Thus

           \indexentry{alpha|(bold}{1}
           \indexentry{alpha|)}{5}

 will become

           \item alpha, \bold{1--5}

 A couple of special cases are worth mentioning here.  First,  entries
 like

           \indexentry{alpha|(}{1}
           \indexentry{alpha|bold}{3}
           \indexentry{alpha|)}{5}

 will be interpreted as

           \item alpha, \bold{3}, 1--5

 but with a warning message in the transcript about the  encounter  of
 an  inconsistent  page  encapsulator.   Secondly,  an  explicit range
 beginning in a Roman page number and ending in Ababic  is  considered
 an  error.   In  a  case  like  this  the  range  is  broken into two
 subranges, if possible, one in  Roman,  the  other  in  Arabic.   For
 instnace,

           \indexentry{alpha|(}{i}
           \indexentry{alpha}{iv}
           \indexentry{alpha}{3}
           \indexentry{alpha|)}{7}

 will be turned into

           \item alpha, 1--iv, 3--7

 with a warning  message  in  the  transcript  complaining  about  the
 illegal range formation.

 Finally, every special  symbol  mentioned  in  this  section  may  be
 escaped by the quote operator (`"').  Thus

           \indexentry{alpha"@beta}{1}

 will actually become

           \item alpha@beta,  1

 as a result of executing makeindex.  However, if quote is preceded by
 escape (`\'), its following letter is not escaped.  That is,

           \indexentry{f\"ur}{1}

 means

           \item f\"ur, 1

 which represents umlaut accented `u' to the family of processors.
