The EXTRAS directory contains files which facilitate the use of the data on   
the disk, but which are not actually required for the use or understanding    
of those data. Included are HTML documents, SPICE kernels, and data producer  
provided software. The HTML files, which may be viewed using a web browser    
and used to navigate the disk, are contained in the HTML subdirectory of      
EXTRAS. They may be accessed individually or via links in the HTML file       
AAREADME.HTM, which is in the root directory of the disk.
