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.
