A library for making epubs that actually works in 3.4.1.
For now, I'm being lazy and just copying the mimetype and container.xml instead of writing it every time.
It's relatively simple.
exampleEpub = Epub()
exampleEpub.addAuthor("Me")
exampleEpub.addTitle("A Book")
exampleEpub.addPublisher("The Publisher")
exampleEpub.addHTML('filepath_of_xhtml_file', 'optional_title')
exampleEpub.addIMG('filepath_of_img')
exampleEpub.create()
