mis notes about awk examples in this dir

make.tcode.awk -- is a good example of how to use "%" to convert frame numbers into 
minutes, seconds and frames.  It should be obvious that if your record has two timecode
fields then you have to do this operation for each one.  The example works on a file
or rather generates a list of timecode for $i lines (records).
