LinuxQuestions.org - How to change style of index in LaTeX?

I like to print index entries in the following latex file with some fancy style, like horizontal lines as seperator between different index entries beginning with a new alphabet or have on letter of alphabet printed. I used these fancy styles a while ago but somehow lost the latex sources and do not remember how to change the activate that option.

Currently following is the index output:

Index

background, 1
H.264, 2
UMTS, 3

I would like something like:

Index

----B-----
background, 1

----H-----
H.264, 2

----U-----
UMTS, 3

Here is the latex file.tex:

Code:

\documentclass[a4paper,10pt]{report}



\usepackage{makeidx}

\makeindex



\usepackage{glossary}

\makeglossary



\author{Luqman Munawar}

\title{Results of Simulation}



\begin{document}

\pagenumbering{roman}

\maketitle



\begin{abstract}

 Some text in abstract

\end{abstract} 



\tableofcontents

\listoffigures

\listoftables

\printglossary

\pagebreak



\pagenumbering{arabic}

\chapter{Background}

\label{chap:background}

Here I will write\index{Writing} some information\index{Information} on background\index{background} of the project.

\chapter{H.264}

\label{chap:h.264}

Here I will write some information\index{Information} on H.264\index{H.264}.



\chapter{UMTS}

\label{chap:umts}

Here I will write some information\index{Information} on UMTS\index{UMTS}.





\printindex

\end{document}

Any hint or pointer to documentation is much appreciated. I did search in the Internet for "latex index styles" or "latex index" but did not find any relevant document.

The closest I found was "Makeindex" by Peter Mosgen:

Code:

\begin{theindex}

{\bf H}

\indexspace

\item Heinrich-Heine-Universit\"at\dotfill 1

\indexspace

{\bf N}

\indexspace\nopagebreak%

\item Neurobiologie\dotfill 1

\end{theindex}

H
Heinrich-Heine-Universitat 1
N
Neurobiologie 1

I would like to avoid editing file.ind manually. Maybe there is an option that can be used to select the style in .tex file?
