R devel - Nov 2012 - Ops.data.frame

Hi all,

Where are the semantics for Ops.data.frame documented?  I've tried
looking in ?Ops.data.frame, ?data.frame, the "R language definition"
(by searching for data frame), and "An Introduction to R" (similarly),
but haven't found anything.  What am I missing?
