Idea is taken from https://github.com/novoid/filetags/pull/30/commits/90d758c917387e66a61555f84bdc0be100778ffb which introduces a variable for counting error cases. It ends with: ``` if num_errors > 0: error_exit(20, str(num_errors) + ' error(s) occurred. Please check messages above.') ``` Maybe this functionality can be added to filetags.
