     LZW compression is used in all GIF files and in compressed TIFF files.  
     The LZW algorithm is patented by Unisys, and April System Design must pay 
     a license royalty to all AniTa users utilizing the LZW algorithm.  
     Because of this, we distribute an encrypted file LZW-algorithm for GIF and 
     compressed TIFF.  The default TIFF import filter can handle uncompressed
     TIFF files.
     
     Please contact April System Design to obtain the decryption key to the LZW
     filters.  Then run 'ANITALZW.EXE' from the AniTa installation directory to 
     extract full LZW support import libraries for both GIF and TIFF.

     We need to know how many AniTa users that will use LZW. April System Design
     will not charge anything extra for the LZW license.
