The project main usage is to convert a .epub file in a .pdf file. The second thing, is to translate the epub file into a chosen language, trying to maintain the same layout of the sheet page.
Like I Said before, the project want to help people translate an ebook, in their own languages.
I'm a Chess Player, so the reason behind this project was to translate ebook in my own language, trying not to touch the moves of chess pieces. So there's more utility than that we spoke before.
