):
    """Call this with osxphotos export /path/to/export --post-function post_function.py::post_function
        This will get called immediately after the photo has been exported

    Args:
        photo: PhotoInfo instance for the photo that's just been exported
        results: ExportResults instance with information about the files associated with the exported photo
        verbose: A function to print verbose output if --verbose is set; if --verbose is not set, acts as a no-op (nothing gets printed)
        **kwargs: reserved for future use; recommend you include **kwargs so your function still works if additional arguments are added in future versions

    Notes:
        Use verbose(str) instead of print if you want your function to conditionally output text depending on --verbose flag
        Any string printed with verbose that contains "warning" or "error" (case-insensitive) will be printed with the appropriate warning or error color
        Will not be called if --dry-run flag is enabled
        Will be called immediately after export and before any --post-command commands are executed
