The background program that parses the files is
written in python. If you prefer to run it locally from the command line or
wish to make personal changes, you can find the script in my github repo HighlightParts
Running it locally allows you to set the output file name or batch process all
files in a folder.
pip install pymupdf
cd Downloads/
python3 highlight.py test.pdf
python3 highlight.py test.pdf -o my_new_file.pdf
python3 highlight.py fuselage_folder/
