        Note that under the mk directory there is a subdirectory called
        former_versions that stores all mk that have been superseded by
        new kernels.
                                                                                                                                             
        Please refer to the aareadme.txt in each of the subdirectories for 
        information on the contents for the specific type of kernels and the 
        corresponding naming conventions.                                                                                
                                                                                
                                                                                
Usage of the SPICE Kernels for JUICE                                 
--------------------------------------------------------                                     
                                                                                
     At least a basic knowledge of the SPICE system is needed in order to    
     use these kernels. The SPICE toolkit provides versions in Fortran       
     (SPICELIB), C (CSPICE), IDL (icy) and Matlab (mice), and the user can   
     choose any one that suits him/her.                                      
                                                                             
     The SPICELIB routine FURNSH, CSPICE function furnsh_c, and icy routine  
     cspice_furnsh load a kernel file into the kernel pool as shown below.   
                                                                             
        CALL FURNSH  ( 'kernel_name' )                                       
        furnsh_c     ( "kernel_name" );                                      
        cspice_furnsh, 'kernel_name'                                         
        cspice_funsh( 'kernel_name' );                                       
                                                                             
     In the case when two or more files contain data overlapping in time     
     for a given object, for binary kernels, the file loaded last takes      
     precedence.                                                             
                                                                             
     If two (or more) text kernels assign value(s) using the '=' operator    
     to identical keywords, the data value(s) associated with the last       
     loaded occurrence of the keyword are used -all earlier values have      
     been replaced with the last loaded value(s).                            
                                                                                
                                                                                
-------------------
