+a quick-fix for fonts which do not have genuine LaTeX support.  It is not
+meant as a replacement of the LaTeX font definition files.  It is meant as
+something more useable for LaTeX users than the @code{\\newfont} command.
+With @code{addfont} the loaded font scales along with the usual LaTeX size
+selection.  Using this package still requires some knowledge on how to use
+fonts with LaTeX.")
