+%description
+The Xvid video codec implements MPEG-4 Simple Profile and Advanced Simple
+Profile standards. It permits compressing and decompressing digital video
+in order to reduce the required bandwidth of video data for transmission
+over computer networks or efficient storage on CDs or DVDs. Due to its
+unrivalled quality Xvid has gained great popularity and is used in many
+other GPLed applications, like e.g. Transcode, MEncoder, MPlayer, Xine and
+many more.
