Description: Szip is an implementation of the extended-Rice lossless compression algorithm.
Long Description: The Consultative Committee on Space Data Systems (CCSDS) has adopted the extended-Rice algorithm for international standards for space applications. Szip is reported to provide fast and effective compression, specifically for the EOS data generated by the NASA Earth Observatory System (EOS). It was originally developed at University of New Mexico (UNM) and integrated with HDF4 by UNM researchers and developers.

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching szip
--->  Verifying checksum for szip
--->  Extracting szip
--->  Configuring szip
--->  Building szip with target all

--->  Staging szip into destroot

--->  Installing szip

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using szip with these commands:

%  man szip
%  apropos szip
