Does anyone know of any way to convert the times in a .score file from  
absolute times to relative times.  For example,

t 0.00;
Left_Hand (0.50) keyNum:e3k;
t 0.25;
Right_Hand (0.50) keyNum:e5k;
t 0.50;
Left_Hand (0.50) keyNum:fs3k;
t 0.75;
Right_Hand (0.50) keyNum:ds5k;
t 1.00;
Left_Hand (0.50) keyNum:gs3k;

converted to

t 0.00;
Left_Hand (0.50) keyNum:e3k;
t + 0.25;
Right_Hand (0.50) keyNum:e5k;
t + 0.25;
Left_Hand (0.50) keyNum:fs3k;
t + 0.25;
Right_Hand (0.50) keyNum:ds5k;
t + 0.25;
Left_Hand (0.50) keyNum:gs3k;

If no solution is offered, I'll probably write a quick c program for it.   
See, I want to tell some of the code to repeat itself, via "repeat n { ...  
}", but you can't put in absolute times in the part that repeats.
