I haven't been using it as a reference, but it appears that Kartikey did 
when he wrote the decoder last year.  I have tried to keep my viewing of 
the code to a minimum, but when Kartikey referenced a GPL source I felt 
that I needed to look deeper into it to find out what other sections are 
based upon it.  When I rewrote much of the code (which hasn't been 
committed yet) I did not use liba52 as a reference.
