+%description
+From the ABOUT file: Laconica (pronounced "luh-KAWN-ih-kuh") is a Free
+and Open Source microblogging platform. It helps people in a
+community, company or group to exchange short (140 character) messages
+over the Web. Users can choose which people to "follow" and receive
+only their friends' or colleagues' status messages. It provides a
+similar service to sites like Twitter, Jaiku, and Plurk.
