       Instructions for Obtaining the NAIF Toolkit                            
                                                                              
                                                                              
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.  Executables for specific programs are             
also available.  To obtain your copy of the software, you should              
follow the instructions below.  Differences among computers may               
necessitate adjustments in the procedure.                                     
                                                                              
Documentation that 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. Connect your browser to the NAIF server using one of the             
         following:                                                           
                                                                              
               ftp://naif.jpl.nasa.gov/pub/naif/toolkit                       
               http://naif.jpl.nasa.gov/pub/naif/toolkit                      
               https://naif.jpl.nasa.gov/pub/naif/toolkit/                    
                                                                              
      2. Select one of the programming languages:                             
                                                                              
               C                                                              
               FORTRAN                                                        
               IDL                                                            
               MATLAB                                                         
                                                                              
      3. Select one of the platforms; for example, the FORTRAN                
         options include:                                                     
                                                                              
               MacIntel_OSX_IFORT_32bit                                       
               PC_Cygwin_gfortran_64bit                                       
               SunSPARC_Solaris_SunFORTRAN_32bit                              
                    and others                                                
                                                                              
      4. At the next level you choose between                                 
                                                                              
               executables                                                    
               packages                                                       
                                                                              
         The executables are individual programs or user guides.              
         The packages are the entire Toolkit as a compressed tar              
         file, or several files with descriptive information                  
         (including a README file).
