6) What is VorTeX and where can I get it?

   VorTeX is a package of programs written at the University of California.
   It includes several nice previewers and some Emacs modes for TeX and
   BibTeX. It is not free. Inquiries should be directed to 
   vortex@ucbarpa.berkeley.edu or
        Professor Michael A. Harrison
        Att. Vortex Dist.
        Computer Science Division
        University of California
        Berkeley, CA 94720
   Actually, the emacs modes are freely available separate from VorTeX
   itself. They are available via anonymous ftp as vortex-macros.tar.Z
   from a.cs.uiuc.edu (128.174.252.1) in ./pub/TeX.
