This tool helps you make sure your LaTeX document compiles without issues.
First, you install it:
$ gem install texqc
Then, you just run it after the LaTeX document is compiled:
$ latexmk -pdf article
$ texqc article
If any warnings were reported by LaTeX, you will get a short list of them and the exit code will be non-zero (very convenient for your CI/CD scripts).
