                This signed Microsoft self-installation file contains binary
                builds that CDF offers, except for the CDF Perl APIs. It
                includes the followings:

                   - CDF core library for C, FORTRAN, and Java APIs
                   - CDF utility tools
                   - Java version of the CDF tools
                   - CDF XML tools
                   - CDF Json tools
                The package, by default, will be installed into
                c:\program files\cdf_distribution\cdf39_2-dist.  Users need to
                have the privilege to install the package there.  Users can
                choose to install the package into a location that requires no
                higher privilege.
                Note: 
                 1. The distributed conversion tool programs between netCDF 
                    and CDF might not be the latest. Please check out the
                    latest ones in
                    https://spdf.gsfc.nasa.gov/pub/software/cdf/conversion_tools/binary/latest_version
                 2. There are scripts (setenv.bat and setenv.ps1) to set up
                    proper environment variables to run the command-line CDF
                    tools and other Java-based applications on Command Terminal
                    or Windows Terminal that fully supports UTF-8. Users can
                    manually place these environment variables into the Windows
                    system properties (run terminal command: sysdm.cpl from a
                    command window and select "Advanced" and "Environment
                    variables", and manually add/change the variables).
