The DOCUMENT directory contains documentation that is considered to be        
either necessary or useful for users to understand the archive data set.      
Documents may be included in multiple forms (ASCII, PDF, MS Word, HTML        
with image file pointers, etc.). Documents in different formats are           
included in subdirectories that collect together those with the same          
content. Included are the following documents.
