    (description
     "Texinfo is the official documentation format of the GNU project.
It was invented by Richard Stallman and Bob Chassell many years
ago, loosely based on Brian Reid's Scribe and other formatting
languages of the time.  It is used by many non-GNU projects as
well.

Texinfo uses a single source file to produce output in a number
of formats, both online and printed (dvi, html, info, pdf, xml,
etc.).  This means that instead of writing different documents
for online information and another for a printed manual, you
need write only one document.  And when the work is revised, you
need revise only that one document.  The Texinfo system is
well-integrated with GNU Emacs.")
