Single-language book format (not bilingual)

[gcharycki]

I would like to translate an EPUB file, for example, from English to French, but I do not want the new file to have the text repeated twice; I want it to appear only once (in French). I would like every word to be in French, not just the content, but also the book title, chapters, etc. How can I achieve this? Unfortunately, I cannot find the required option.

I still get this kind of irregular mashup.

For that command:

py make_book.py --book_name test_books/animal_farm.epub --openai_key XXX --test --single_translate --language pl
