\description{
Association scores changed in 1.4.0, so files from before it are recomputed
rather than used (see \link{cacheAs}). Where a file is known to hold what this
version would compute - because it was written by a development version that
already had the corrections, for instance - this records that, and the file is
used again as it is.
}
\details{
What actually wrote a file is left as it stands; the blessing is recorded
beside it, so that \code{\link[=cacheAsInfo]{cacheAsInfo()}} keeps telling the truth about where the
numbers come from.

A file that records no parameters, as those written before 1.3.0.9000 do, has
nothing left to be compared against a call once it is blessed, and is
therefore reused for any call that names it. Bless such a file only if that
is what you mean.
