I need "indexing" software for troff documents. The Sys V "subj" and
"ndx" facilities are not flexible enough so I am sourcing something
better. The program must be able to make an educated guess at what
the document is about and provide indecies including page numbering
ready to be processed by troff. 

Any useful software will do i.e awk shell scripts etc ...

ANY HELP or suggestions on this are much appreciated. The software is
to enable me to create an index for my new book about to be published
by Prentice Hall Q4 1990.

IF YOU VAN HELP, I WILL ACKNOWLEDGE YOUR CONTRIBUTION IN THE BOOK.

Much appreciated
