The files in the directories below have been archived with the UNIX
"tar" command, compressed with the "compress" command, and chopped
into pieces no larger than 100,000 bytes.  (The chopping is done
because some systems do not allow ftp transfer of files larger than
approximately 100Kb.)  To reconstitute the compressed tar file, simply
concatenate all the files in the directory into one "tarfile."  Under
UNIX, this can be accomplished with the following command:

        cat *part* > XXX.tar.Z

Where "XXX" is the name of the tarfile.  (This name should be obvious
from the names of the chopped files.)  Then the file may be
uncompressed with:

        uncompress XXX.tar.Z

And un-tar-ed with:

        tar xvf XXX.tar

After un-tar-ing the files, you should see a new directory called
"HDF3.3r2" under your current directory.  If you "cd" into that directory,
there is a README and an ABOUT_3.3r2 file to direct you in building the 
base HDF library and the HDF/netCDF library.
