# does not work as latex does not preprocess svg. latex speaks of inputenc. Don't know how to configure
# workaround: run inkspace and convert to png inside the _build/doctrees/pdf folder
# edit solidity.latex and change the text from logo.svg to logo.png
# do the same for solidity.fts (generated file?)
# todo: find a better workaround

# run pandoc from the sphinx generated _build/html folder. index.html is the starter page.
pandoc -f html -t latex -o solidity.pdf index.html
# there is one error, keep going by pushing enter until the dblatex command completes

# display the PDF document, looks good
