+Sweeper helps to clean unwanted traces the user leaves on the system and to
+regain disk space removing unused temporary files.
+It can quickly remove temporary information, such as web page cookies,
+browser history, or the list of recently-opened documents.  It helps provide
+additional privacy on a system shared between multiple users.")
