Yeah, it was a mistake on our part to name it pd-devel, since its not

something like "gui-rewrite", since it does not share anything with  
earlier pd-devel branches.

I have the audacity to believe that peoples everywhere can have three  
meals a day for their bodies, education and culture for their minds,  
and dignity, equality and freedom for their spirits.      - Martin
