\usage{

\item{SCHWEINGRUBER}{Is the file in the Schweingruber-type Tucson format?}

\description{
This function includes improvements to the \code{\link{read_crn}} function from the
\pkg{dplR} library. The principle changes are better parsing of metadata, and support
for the Schweingruber-type Tucson format. Chronologies that are unable to be read
are reported to the user. The user (or \code{\link{read_crn}}) must tell the function whether
the file is a Schweingruber-type chronology.
