+display quotations.  It is designed for a wide range of tasks ranging from the
+most simple applications to the more complex demands of formal quotations.
+The facilities include commands, environments, and user-definable 'smart
+quotes' which dynamically adjust to their context.  Quotation marks are
+switched automatically if quotations are nested and they can be adjusted to
+the current language if the babel package is available.  There are additional
+facilities designed to cope with the more specific demands of academic
+writing, especially in the humanities and the social sciences.  All quote
+styles as well as the optional active quotes are freely configurable.")
