This package defines some macros as a replacement for \index which makes live easier. You have to type every word only once to get it into the index and into the text. Save the file hvindex.sty in a directory, which is part of your local TeX tree. Then do not forget to run texhash to update this tree. For more information see the documentation of your LaTeX distribution on installing packages into your local TeX system or read the TeX Frequently Asked Questions: (http://www.tex.ac.uk/cgi-bin/texfaq2html?label=instpackages). %% This program can be redistributed and/or modified under the terms %% of the LaTeX Project Public License Distributed from CTAN archives %% in directory macros/latex/base/lppl.txt.
