Routine Description:
    Parses command line arguments and sets the appropriate flag.

Arguments:
    argc             : The number of command line args.
    argv             : Command Line arguments
    pdwCmdLineOption : Pointer to DWORD where the flags are set.

Return Value:
    S_OK if parsing was succesful and the command line arguments could be meaningfully
    decoded.
