Dear Karl,

I was able to contact Yuan Xu, the original author of pgf-pie, who is
also the author of pgf-umlcd and pgf-umlsd.  We agree that
maintainership will be handed over to the pgf-tikz GitHub organization,
which Yuan will be made a part of.  This will solve the maintainability
problem in the long run because there are several people with write
access that can release new version (David Carlisle, Joseph Wright, and
myself).  Also the licensing situation will be cleared up and the same
LPPLv1.3c + GPLv2 double licensing as for PGF will be put in place.

Cheers, Henri
