[linux-audio-dev] gwc-lib released on sourceforge

[Davy Durham]

Hey Jeff!

(Hey it's the author of ReZound, we had talked a while back about moving 
functionality into ReZound)

Just to let you know, I changed jobs, so my old email address 
(david.durham at wcom.com) is no more.  Use this email if you need to get me.

Well, it's good to see your fine functionality being moved into a lib. 
:)  I'm going to check it out right now.

Just letting you know that I noticed,
