Some of the documentations of Julia packages on the webpages generated with Documenter.jl are so good that I want to convert them into full structured PDF so that I can print and read them just like reading papers or books. For example, this is the web documentation of the package JuMP and here is its corresponding PDF format, but not all packages provide documentations in PDF version. Is there some method to export all the structure and content of them from the webpages to a PDF?
