When you create documentation for the GNU operation system, you write a
foo.texi file.  This file contains TeX macros defined in texinfo.tex
file, and can be processed using tex (the command) to generate the
foo.dvi file.  The same set of macros that's contained in the foo.texi
file, can be processed by a different processor makeinfo to generate the
foo.info file.

The foo.dvi file is the DeVice Independent file.  It contains fonts and
formatting information ready to be processed by a dvi processor to
generate outputs suitable for a particular device.  For example, running
"dvips foo.dvi" will generate a PostScript file suitable to be sent to a
PostScript printer.  Similarly, running "dvilj4 foo.dvi" will generate a
PCL file suitable to be sent to a HP LaserJet 4 printer.  Running
"dvivga foo.dvi" will generate display of the foo.dvi file on your
screen for previewing.  Other commands exists to convert the foo.dvi
file into other formats.

The foo.info file is essentially an ASCII file.  It contains markers
liking one part of the file to another part of the file.  You can browse
the foo.info file using the info command, or the Emacs info facility.

All of the above existed long before HTML or PDF came along.  Nowadays,
you can generate HTML and PDF files from your foo.texi source.
