[OS X TeX] Chapter Index

[Alain Schremmer]

For each chapter of a book, I would like to have an index at the end  
of the chapter.

The various ChapterNtext.tex of the book are included in a source  
file, BookRoot.tex.
But, in order to work on individual chapters, I also have individual  
root files, ChapterNroot.tex .

So, by having \printindex in each ChapterNroot.tex, I have an index  
at the end of the chapter when I typeset it with ChapterNroot.tex.

What I would like, though, is to have these chapter indexes also when  
I typeset with BookRoot.tex

In other words, something similar to what I get with titletoc (a  
companion to the titlesec package), namely both chapter tocs and a  
book toc.

I could not find anything like titledoc for indexes.

Hopeful regards
