       Instructions for Obtaining the NAIF Toolkit via FTP                    
                                                                              
                                                                              
The NAIF Toolkit provides access to SPICE files.  Files include               
spacecraft and planetary ephemerides (SPK files), instrument mounting         
information (IK files), attitude data for spacecraft (CK files),              
and histories of events (EK files).                                           
                                                                              
NAIF has compressed tar files that contain the Toolkit software for           
various operating systems.  They are on a Sun SPARCstation 2 that             
supports anonymous ftp. To obtain your copy of the software, you              
should follow the scenario described below.  Note that your computer          
may have different prompts and may not have the same implementation           
of ftp as the NAIF Sun. If you have problems with ftp, contact your           
system administrator. If you still have problems, contact NAIF.               
                                                                              
Documentation which accompanies the Toolkit describes formats of the          
files.  In the DOCUMENT directory of this archive volume see also             
TK_DESCR.TXT and TK_INSTL.TXT, short descriptions of the Toolkit              
organization and installation.                                                
                                                                              
      1. ftp to the NAIF Sun                                                  
                                                                              
               ftp naif.jpl.nasa.gov                                          
                                                                              
                                                                              
         If this address cannot be resolved, try the numeric address          
         for naif, 128.149.126.11                                             
                                                                              
      2. Login as the user anonymous.                                         
                                                                              
               ftp> user anonymous                                            
                                                                              
               (or if you're given a prompt:                                  
                                                                              
                   Username: anonymous                                        
                                                                              
                   Name (han:naif): anonymous )                               
                                                                              
                                                                              
      3. Enter your e-mail address for the password.                          
                                                                              
               Password: user@host                                            
                                                                              
                                                                              
      4. Change directory to where the toolkit files are located.             
                                                                              
               ftp> cd pub/naif/toolkit                                       
                                                                              
      5. Use the "dir" command to see the list of operating systems           
         supported.  Then "cd" to the appropriate directory.  For example,    
         if you have a Sun Solaris system, you would type:                    
                                                                              
               ftp> dir                                                       
               ftp> cd Sun_Solaris                                            
                                                                              
                                                                              
      5. "get" the README, dscriptn.txt, and install.csh files in             
          ASCII mode.  If the ftp default mode on your machine is binary,     
          you should change to ASCII mode first.                              
                                                                              
               ftp> ascii                                                     
               ftp> get README                                                
               ftp> get dscriptn.txt                                          
               ftp> get install.csh                                           
                                                                              
                                                                              
      6. Set the transfer mode to binary.                                     
                                                                              
               ftp> bin                                                       
                                                                              
                                                                              
      7. "get" the compressed tar file toolkit.tar.Z. This tar                
          file contains the NAIF Toolkit software.                            
                                                                              
               ftp> get toolkit.tar.Z                                         
                                                                              
    Follow the instructions in the files README and dscriptn.txt and          
extract the files. Do not build the executables or object library --          
they are included in the compressed file. Try them out first to see           
if they work on your machine. If they don't, then you'll want to              
rebuild them.
