Netcdf-IO for PDL

 This is the PDL interface to the Unidata NetCDF library. It uses the
 netCDF version 3 library to make a subset of netCDF functionality
 available to PDL users in a clean, object-oriented interface.
 .
 Another NetCDF perl interface, which allows access to the entire range
 of netCDF functionality (but in a non-object-oriented
 style which uses perl arrays instead of PDLs) is available through Unidata at
 http://www.unidata.ucar.edu/packages/netcdf/index.html.
 .
 The NetCDF standard allows N-dimensional binary data to be efficiently
 stored, annotated and exchanged between many platforms.
 .
 When one creates a new netCDF object, this object is associated with one
 netCDF file.
