+    (description
+     "The package numprint prints numbers with a separator every three
+digits and converts numbers given as 12345.6e789 to 12\\,345,6\\cdot
+10^{789}.  Numbers are printed in the current mode (text or math) in
+order to use the correct font.
+
+Many things, including the decimal sign, the thousand separator, as
+well as the product sign can be changed by the user, e.g., to reach
+12,345.6\\times 10^{789}.
+
+If an optional argument is given it is printed upright as unit.
+Numbers can be rounded to a given number of digits.  The package
+supports an automatic, language-dependent change of the number format.
+
+Tabular alignment using the tabular, array, tabularx, and longtable
+environments (similar to the dcolumn and rccol packages) is supported
+using all features of numprint.  Additional text can be added before
+and after the formatted number.")
