+The {\tt rw} package provides a very rudimentary binary I/O capability
+for quickly writing {\it single record} direct-access Fortran binary files. 
+It is primarily used for writing diagnostic output.
+
+\subsection{Introduction}
+Package {\tt rw} is an interface to the more general {\tt mdsio} package.
+The {\tt rw} package can be used to write or read direct-access Fortran 
+binary files for two-dimensional XY and three-dimensional XYZ arrays. 
+The arrays are assumed to have been declared according to the standard
+MITgcm two-dimensional or three-dimensional floating point array type:
+\begin{verbatim}
+C     Example of declaring a standard two dimensional "long" 
+C     floating point type array (the _RL macro is usually 
+C     mapped to 64-bit floats in most configurations)
+      _RL anArray(1-OLx:sNx+OLx,1-OLy:sNy+OLy,nSx,nSy)
+\end{verbatim}
+
+Each call to an {\tt rw} read or write routine will read (or write) to
+the first record of a file. To write direct access Fortran files with
+multiple records use the package {\tt mdsio} (see section
+\ref{sec:pkg:mdsio}).  To write self-describing files that contain
+embedded information describing the variables being written and the
+spatial and temporal locations of those variables use the package {\tt
+  mnc} (see section \ref{sec:pkg:mnc}) which produces
+\htlink{netCDF}{http://www.unidata.ucar.edu/packages/netcdf}
+\cite{rew:97} based output.
