+libLTC
+------
+
+Linear (or Longitudinal) Timecode (LTC) is an encoding of SMPTE timecode data
+as a Manchester-Biphase encoded audio signal.  
+The audio signal is commonly recorded on a VTR track or other storage media.
+
+libltc provides functionality to encode and decode LTC audio from/to 
+SMPTE timecode, including SMPTE date support.
