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: cfg_tropts.m
    path of file: ./repos/spm12/matlabbatch
    
    the code of the file until where you have to start completion: function tropts = cfg_tropts(stopspec, clvl, mlvl, cnt, mcnt, dflag)

% function tropts = cfg_tropts(stopspec, clvl, mlvl, cnt, mcnt, dflag)
% This function is a shorthand that generates a traversal options structure
% from the following items:
% stopspec -   a find spec shorthand as input to cfg_findspec (see
%              cfg_findspec for details)
% clvl, mlvl - current/maximum tree level

    
function tropts = cfg_tropts(stopspec, clvl, mlvl, cnt, mcnt, dflag)

% function tropts = cfg_tropts(stopspec, clvl, mlvl, cnt, mcnt, dflag)
% This function is a shorthand that generates a traversal options structure
% from the following items:
% stopspec -   a find spec shorthand as input to cfg_findspec (see
%              cfg_findspec for details)
% clvl, mlvl - current/maximum tree level
% cnt, mcnt - found items/maximum #items
% dflag      - traverse val/values part of tree
%
% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
% for a general overview.
