RE: [Plib-devel] Work outstanding.

Perfly is also "the ultimate judge" on whether a particular feature
of Performer has been tested.  If it is in Perfly, you can almost
guarantee the Performer team has looked at it.

A friend has said that it only took him a few tries to realize that
you don't start from scratch with Performer, you start with Perfly.

(Note I am not suggesting that PFly become some sort of uber-example.)
