a better way to obtain all travis logs: try up to 100 jobs, exit on failure
another possibility for failed packages
add a function to analyze failed packages due to latex pkgs, and the ones that need to be re-checked for the next job
also try to find font packages
some typos, and pkgs should be unique
reduce packages
