This directory contains the packed/unpacked source code

          contains an overview HDF3.3, discussion on 
          the new features in HDF3.3 and description of 
          changes in Vdata and Vgroup interfaces.

Subdirectories:

1. unpacked -- contains all source code.

              The patch files can be used to patch the 
              source code in the subdirectory unpacked/.
3. tar -- contains compressed UNIX archived source code,
          the code in unpacked/. Users should check the

          Getting Started' for HDF3.2 can be used temporarily.
          
Each subdirectory has a README file explaining which files are 
there in that directory and how to use those files.
