                       This is a self-installation pre-built package for 
                       Intel Mac OS X (32/64-bit) of 10.5 or later.
                       All libraries and executables are universal binary. 
                       Download and double-click the downloaded file for 
                       installation. This file will be extracted to
                       CDF371*ub.pkg.

                       This package contains everything CDF offers except for 
                       the CDF Perl and C# APIs and contains the following:

                        - pre-compiled CDF library (for C, FORTRAN, and Java)
                        - complete suite of the CDF tools (both GUI-based and
                          command-line-based)

                       Note: 1. If the package can't be installed as a package
                                of the same version already exists. Go to
                                /Library/Receipts folder and remove the package
                                CDF371*ub.pkg (needs to have the administrator
                                authority).
                             2. The distributed tool programs include the
                                netCDF-CDF converters. They might not be the
                                latest. Please check out the latest ones in
                                https://spdf.gsfc.nasa.gov/pub/software/cdf/conversion_tools

src_distribution       Directory where the CDF source distribution is 
                       available.  Go here if you want to build your
                       own CDF library and tools.

PerlCDF37_1.tar.gz     Compressed tarred file that contains source for 
                       Perl-CDF APIs.  Download this if you are planning on 
                       building the APIs yourself. You need to install the CDF
                       library prior to building and using the Perl APIs.

PerlCDF37_1-setup.tar.gz    This is a compressed, pre-compiled Perl-CDF APIs.
                       The files will be extracted into directory PerlCDF37_1.
                       This distribution is linked with the static CDF library
                       so there is no need to install other CDF package if
                       Perl is the only APIs you need. The bundled binary works 
                       for perl running on either 32 or 64-bit mode on an Mac
                       Intel. 

cdfjava.jar            This is the latest version of cdfjava.jar that
                       contains the latest Java APIs.  This file is also
                       included in cdf37_1-setup_universal_binary.tar.gz.
                       It is here for those who installed the Java APIs a while
                       back, and might not have the latest Java APIs.

                       If you are not sure whether you have the latest
                       version of the Java APIs, download this file and
                       replace the one you have in the
                       <cdf37_1_dir>/cdfjava/classes directory and 
                       <cdf37_1_dir>/CDFToolsDriver.app/Contents/Resources/Java
                       directory.

cdfml.jar              This file contains the latest version of the CDF XML
                       utilities (written in Java). This file is also included
                       in cdf37_1-setup_universal_binary.tar.gz. It is here
                       for those who already have downloaded and installed an
                       old version of pre-built binary file.

                       If you are not sure whether you have the latest
                       version of the CDF XML tools, download this file and
                       replace the one you have in the
                       <cdf37_1_dir>/cdfjava/cdfml directory and
                       <cdf37_1_dir>/CDFToolsDriver.app/Contents/Resources/Java
                       directory.
