        !            14: strtok helps  to divide a  string into a set  of tokens.  string1
        !            15: points to  the string  to be divided,  and string2 points  to the
        !            16: character or characters that delimit the tokens.

        !            18: strtok divides a string into tokens by being called repeatedly.
        !            19: 
        !            20: On the  first call to strtok, string1 should  point to the string
        !            21: being  divided.  strtok  searches  for a  character  that is  _n_o_t
        !            22: included within string2.  If it finds one, then strtok regards it
        !            23: as the  beginning of the  first token within the  string.  If one
        !            24: cannot  be found,  then strtok  returns NULL  to signal  that the
        !            25: string could  not be divided into tokens.   When the beginning of
        !            26: the first token is found,  strtok then looks for a character that
        !            27: _i_s included  within string2.  When one  is found, strtok replaces
        !            28: it with  a null  character to  mark the end  of the  first token,
        !            29: stores  a pointer  to the  remainder of  string1 within  a static
        !            30: buffer, and  returns the  address of  the beginning of  the first
        !            31: token.
        !            32: 
        !            33: On subsequent calls to  strtok, set string1 to NULL.  strtok then
        !            34: looks for subsequent tokens, using the address that it saved from
        !            35: the first call.  With each call to strtok, string2 may point to a
        !            36: different delimiter or set of delimiters.
