In our book, UNIX Text Processing, (Hayden Books/Howard
Sams, April 1987), Dale Dougherty and I discuss this topic
in detail.  You can write a macro that prints out an index
entry plus a page number; this data can either be collected
into a diversion, or preferably written to stderr with the
.tm request (in otroff or ditroff) or directly into a file
with .sy echo (ditroff only).

This file can be postprocessed with sort, awk and sed to combine
multiple entries, and to format the index properly.

Ptx is not all that useful, but if you need to make one, you
need it.  The process is too long to go into here (since I'm
reading news early one morning over a long-distance phone
link while ostensibly on vacation), but if
you send me mail, I'll send you out details when I get back
to the office in a couple of weeks.  

If there is sufficient interest, I'll post the discussion to
the net.  (Note:  ptx is not covered in our book.  Sorry.)
