        |- [CK]      This file describes SPICE pointing 
        |            data (called C-kernels) and their usage within SPICE.
        |
        |- [DAF]     This file describes the internal
        |            structure of binary SPICE kernels (CK and SPK).
        |
        |- [KERNEL]  This file describes the internal structure
        |            of ASCII SPICE kernels (TLS, TSC, TPC, etc.)
        |
        |- [PCK]     This file describes the planetary constants
        |            kernel (TPC)
        |
        |- [SCLK]    This file describes the spacecraft
        |            clock kernel (TSC) and the conversion of clock values into
        |            time values.
        |
        |- [SPK]     This file describes the spacecraft and planetary
        |            ephemeris data kernels (SP-kernel) and their usage within SPICE.
        |
        |- [TIME]    This file describes time represetations
                     and conversions between them.
