+    (description
+     "The package supports a number of features of the Latin Modern fonts
+which are not easily accessible via the default (La)TeX support.  In
+particular, the package supports the use of the various styles of digits
+available, small-caps and upright italic shapes, and alternative weights and
+widths.  It also supports variable width typewriter and the @code{quotation}
+font.
+
+By default, the package uses proportional oldstyle digits and variable width
+typewriter but this can be changed by passing appropriate options to the
+package.  The package also supports using (for example) different styles of
+digits within a document so it is possible to use proportional oldstyle digits
+by default, say, but tabular lining digits within a particular table.")
