You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ft_reproducescript.m
    path of file: ./repos/fecgsyn/subfunctions/data-generation/libs/fieldtrip
    
    the code of the file until where you have to start completion: function ft_reproducescript(cfg)

% FT_REPRODUCESCRIPT is a helper function to clean up the script and intermediate
% datafiles that are the result from using the cfg.reproducescript option. You should
% call this function all the way at the end of your analysis. This function will look
% at all intermediate files in the output directory, remove input and output files
% that are the same and update the script accordingly.
%
% Use as
%   ft_reproducescript(cfg)
%
% The configuration structure should contain
%   cfg.reproducescript = string, directory with the script and intermediate data
