17) How do I generate an index in TeX/LaTeX?

    Making an index is not trivial. There are several indexing programs
    which aid in doing this. Some are:
      makeindex - for LaTeX under Unix (but runs under other OS's
         without changes). Available via anonymous ftp from 
         ymir.claremont.edu (134.173.4.23, VMS) in the directory
         [.tex.utilities.makeindex]. A version for the Macintosh is
         available from Johnny Tolliver at 
         tolliver%atf.mfenet@nmfecc.llnl.gov. The Makeindex documentation
         is a pretty good source of information on how to create your
         own index.
      idxtex - for LaTeX under VMS. Available via anonymous ftp from
         ymir.claremont.edu in the directory [.tex.utilities.idxtex].
      texix - for TeX on CMS and Macintosh machines. Available via
         anonymous ftp from ymir.claremont.edu in the directory
         [.tex.utilities.texix].
      indexor - for LaTeX under Unix, VMS, and DOS. Available via
         anonymous ftp from ymir.claremont.edu in [.tex.utilities.indexor].
      texindex - for LaTeX under Unix. Available from
         comp.sources.misc archives in Volume 23.
