PRESTO! scheme

Does anyone know any resource in which I can find the theory behind PRESTO! scheme used in Fluent?

As for the user guide, I understand that instead of interpolating, the pressure is calculated on the faces by some method similar to the one used in the original staggered grid scheme.

I would appreciate if anyone explain the following sentence form the manual:
"the discrete continuity balance for a "staggered'' control volume about the face to compute the "staggered'' (i.e., face) pressure"

Hello there,

Did you find any reference on the Presto method?

Thank you
