+     "This class makes it easy to generate tables that show many different kerning
+pairs of an arbitrary font, usable by LaTeX.  It shows the kerning values that
+are used in the font by default.  In addition, this class enables the user to
+alter the kernings and to observe the results.  Kerning pairs can be defined
+for groups of similar glyphs at the same time.  An @file{.mtx} file is
+generated automatically.  The @file{.mtx} file may then be loaded by
+@code{fontinst} to introduce the user-made kernings into the virtual font for
+later use in LaTeX.")
