The -t0 format is the score.srt format.  For a very long time Csound  
has accepted a pre-sorted score with original times and warped time  
information, usinf the scort.srt file which was always produced.  Now  
this file is all internal, so I rather think that no one actually uses  
this since computers are faster and the sorting algorithm was so much  
improved to smoother sort, and -t0 is only used for information.
