#' Access to GDAL/OGR data sources is accomplished with \code{openGDAL} and 
#' \code{openOGR}. These return S4 classes holding pointers to the GDAL/OGR data
#' structures. Stanard R-like access function are provided. These S4 objects are 
#' convertable to grid graphics objects. A generic \code{draw} function is
#' provided for building plots.
