Description    : The Pack utility compresses files using Huffman (minimum 
                 redundancy) codes on a byte-by-byte basis.  The amount of 
                 compression obtained depends on the size of the file and its 
                 character distribution, but typical text and run files show a 
                 reduction to 60-75% of their original size.
                 
                 Unpack is used to expand files compressed using the Pack
                 utility.
                 
Directions/Use : The Pack utility accepts four parameters, one mandatory and   
                 three optional:
        
                 Input file(s)           
                 
                 This field is mandatory.  Is a list of files to be compressed.
                 
                 [Force packing?]        
                 
                 This field is optional.  The default is 'No'.  If 'Yes', all 
                 files are packed whether or not there is any actual size 
                 reduction.
                 
                 [Display statistics?]   
                 
                 This field is optional.  The default is 'No'.  If 'Yes', 
                 statistics are reporting showing the actual byte reduction, 
                 the number of distinct bytes, and information regarding the 
                 Huffman tree created.
                 
                 [Delete original file?] 
                 
                 This field is optional.  The default is 'No'.  If 'Yes', the 
                 original, unpacked version of the file will be deleted from 
                 the disk.
                 
                 The Unpack utility accepts one mandatory parameter:
                 
                 File list   
                 
                 Is a list of compressed files.  The packed suffix (.z) is 
                 optional.
