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.
