Dear Rob

I've looked at the compile_playrec script. To be honest, I couldn't  
make much sense from it because I lack the knowledge about how these  
things work (Matlab-GUIs, compiler options, etc.). However, I am  
pretty sure it should be possible to make a similar script that works  
without a whizz-bang GUI, but uses the terminal instead to ask the  
user a few questions. This should then work with Octave, too. What do  
you think? Maybe you could even make an Octave package from it (see  
http://octave.sourceforge.net ).
