# Default make weasyprint target has a bug so we have to call it manually on the generated index.html file
|
||||
# Then we execute count_pdf_pages.py that will count the number of pages, and update print-theme.css
|
||||
# Then we generate index.pdf again (with the correct number of pages in the footer)
|
||||
# After that, extract table of content data from the pdf and generate a .tex file
|
||||
# Then generate a toc.pdf from the .tex file
|
||||
# And put them together in a .pdf file
|
||||
# Finally, we generate the final PDF by adding the bookmarks (for easier navigation in the PDF)
|
||||
# After all, clean up
