+\usage{
+cacheAsInfo(cacheAs)
+}
+\arguments{
+\item{cacheAs}{path to the file, with or without its \code{.rds} extension}
+}
+\value{
+a list with the elements \code{scoreVersion}, \code{packageVersion},
+\code{parameters}, \code{dots},
+\code{apiUrl} and \code{indexRevision}, or \code{NULL} for a file written by a version
+before 1.4.0, which recorded none of this
+}
+\description{
+Reads back what a query function recorded in a \link{cacheAs} file: the parameters
+it was called with, the KorAP instance it asked, the index revision that
+instance's corpus had at the time, and the version of RKorAPClient that wrote
+the file. Useful for saying, of a result kept next to a document, what the
+numbers in it rest on.
