Lest anyone think that the PRDB was single-backbone-specific in
_design_ or capability (it pretty much was in terms of data), let
me note that, when Andy Adams and I rewrote the PRDB from a SPIRES
DB to a RDBMS (with help from Tom Libert and Sue Hares), we explicitly
designed in the ability to include data from other backbones.
This was initially done to support both the T1 and T3 backbones, but
it could easily have supported other backbones as well.
