    Numbers are recorded in the 32 bit unsigned binary form of the
    endianness of the machine generating the file. 64 bit numbers are
-   stored as two 32 bit numbers, the low part first.  Strings are
-   padded with 1 to 4 NUL bytes, to bring the length up to a multiple
-   of 4. The number of 4 bytes is stored, followed by the padded

    string. Zero length and NULL strings are simply stored as a length
    of zero (they have no trailing NUL or padding).
