%%% ====================================================================
%%% This file contains changes to uuthesis-2016-d (or later) to
%%% provide support for an end-of-thesis subject index.  It must be
%%% used INSTEAD of the standard LaTeX makeidx package, because it
%%% needs to define additional macros and formatting compatible with
%%% the University of Utah Thesis Office regulations.
%%%
%%% Modern machines are sufficiently fast that there is no observable
%%% time savings from suppressing index generation, so this file
%%% always issues the \makeindex command.
%%%
%%% Usage:
%%%
%%%     \documentclass {uuthesis2e}
%%%     ... other \usepackage{...} commands ...
%%%     \usepackage    {uuthesis-2016-d}
%%%     \usepackage    {uuthesis-index}
%%%     ... front matter definitions ...
%%%     \begin {document}
%%%     ...
%%%     \bibliography  {siam}
%%%     \printindex
%%%     \end   {document}
%%%
%%% Two aspects of the formatting are user controllable via commands
%%% issued just before the \printindex command:
%%%
%%%     \columnsep = 0pt                % change from nonzero default
%%%     \renewcommand{TOPIC INDEX}      % change from SUBJECT INDEX default
%%%
%%% That location is also a reasonable place to insert index cross
%%% references, like these examples:
%%%
%%%     \index{DCT|see{Discrete Cosine Transform}}%
%%%     \index{DWT|see{Discrete Wavelet Transform}}%
%%%     \index{DCT|seealso{Discrete Wavelet Transform}}%
%%%     \index{DWT|seealso{Discrete Cosine Transform}}%
%%%     \index{mu@$\mu$ (mu)|see{Borel measure}}%
%%%     \index{m|seealso{mu (\$mu$)}}%
