Compressing a massive TeX folder for submitting to arxiv

I keep forgetting how to do this well, and most of the tricks I find if I just google don’t work for me. So, future Silvia, here’s what you do:

1. Run pip install arxiv-latex-cleaner
2. Run arxiv_latex_cleaner --compress_pdf path/to/tex/folder
3. Compress the new folder path/to/tex/folder-ArXiv and upload that to ArXiv
