Lout is a new batch formatter drawing a fair bit from TeX and troff.
Its main strengths are a more powerful and much easier to use "macro"
programming language, and is reputed to be as "complete" as TeX or
the troff formatting suite.  It only generates PostScript and ascii.

Lout was written by Jeff Kingston (jeff@cs.su.oz.au) and
is available via anon FTP from ftp.cs.su.oz.au directory "jeff".

Subject: GN12. Where can I find indexing software?

Liam Quin <lee@sq.sq.com> is one of the net "experts" in this field,
and suggests the following:

SMART is from cornell, and is a test-bed for the research done by
Gerald Salton's group; it's also quite widely used by other researchers.

qx (or gx?) is an Australian system that went by on the net recently.

WAIS is a client-server system.

lq-text is my own system.

You can find all of the above (except probably qg/gx since I haven't given
a good enough name) with archie; lq-text 1.13 is at ftp.cs.toronto.edu.

An _excellent_ book to look at or get or run out and buy is

    %T Information Retrieval: Data Structures and Algorithms
    %I Prentice-Hall
