+Giuseppe Peano at the beginning of the last century.  This simplified Latin is
+designed to be an instrument for international cooperation, especially in the
+academic sphere.  This package provides the necessary translations to use the
+language within a LaTeX document.  It also imports @code{fontenc} in order to
+be able to use ligatures and quotation marks.  Finally, it offers a text in
+Interlingua that can be used as a dummy text: @emph{Fundamento de
+intelligentia}.")
