* od_parse_cmd_line()
*
* Function to parse an OpenDoors program's command-line, interpreting
* standard command-line parameters. This is one of the few OpenDoors APIs
* that will not automatically initialize OpenDoors if it hasn't already
* been done. This is because od_parse_cmd_line() performs setup that must
* be done prior to OpenDoors initialization.
*
* Parameters: FOR NON-WIN32 VERSIONS:
*
* nArgCount - Number of command line arguments, as passed to
* main() in argc.
*
* papszArguments - Pointer to array of pointers to string
* arguments, as passed to main() in argv. The
* first element of this array (usually the
* full path and filename of the executable)
* is ignored.
*
* FOR WIN32 VERSION:
*
* pszCmdLine - Pointer to the command line string, as passed
* to WinMain().
*
* Return: void
