A *much* more flexible tool is xindy, written in clisp. Since it is part of texlive 2012, it is available ready-to-run for many platforms. http://www.xindy.org Unfortunately, noone has written a proper style file for roff, AFAIK. I believe it shouldn't be too difficult, and its author, Joachim Schrod, can certainly help. Werner
