The "g.data" package on CRAN stores R objects in individual files,
like the (old) S-Plus model.  The timestamp on a file tells you the
last time "g.data.save()" was invoked on that object.  Its primary
purpose is to make objects available (as promises) without filling
up memory until an object is actually used.
