-NetCDF data is:
+Optional HDF4 support
+---------------------
 
-   * Self-Describing. A netCDF file includes information about the
-   data it contains.  
-   * Portable. A netCDF file can be accessed by computers with different 
-   ways of storing integers, characters, and floating- point numbers.  
-   * Scalable. A small subset of a large dataset may be accessed 
-   efficiently.  
-   * Appendable. Data may be appended to a properly structured netCDF 
-   file without copying the dataset or redefining its structure.  
-   * Sharable. One writer and multiple readers may simultaneously access
-   the same netCDF file.
-   * Archivable. Access to all earlier forms of netCDF data will be
-   supported by current and future versions of the software.
+If you need support for reading HDF4 files, please build and install the 'hdf'
+package from SlackBuilds.org, and then pass the option 'HDF4=yes' to the netcdf
+SlackBuild, for example
 
-The netCDF software was developed by Glenn Davis, Russ Rew, Ed Hartnett,
-John Caron, Steve Emmerson, and Harvey Davies at the Unidata Program
-Center in Boulder, Colorado, with contributions from many other netCDF
-users.
