Dear Matt,<br><br>Thank you for your email. Re-writing expr with BSD 
license has been on my mind for a while and I would like to do it. I do 
not need to be paid, but I like the idea of collecting money for 
donation to a non-profit organization that could help cultivate computer
 music, specially one that uses free software.  So, your pledges would 
motivate me more. Do you (or Miller) know of such a fund/scholarship?  I
 cannot promise you when this will happen, but I will make it a high 
priority item on my work list.<br>
<br>Please feel free to share this email with the list.<br><br>best,<br>Shahrokh
