+Ogg is a \href{http://www.xiph.org/}{Xiph.Org Foundation} effort
+to protect essential tenets of Internet multimedia from corporate
+hostage-taking; Open Source is the net's greatest tool to keep
+everyone honest. See \href{http://www.xiph.org/about.html}{About

+Ogg Vorbis is the first Ogg audio CODEC.  Anyone may freely use and
+distribute the Ogg and Vorbis specification, whether in a private,
+public or corporate capacity.  However, the Xiph.Org Foundation and
+the Ogg project (xiph.org) reserve the right to set the Ogg Vorbis
+specification and certify specification compliance.
