    let mut book = Book::from_file("book.epub")?;

    println!("Title: {}", book.metadata().title);
    println!("Sections: {}", book.spine().len());

    // Export any format to standard binary EPUB3 ZIP bytes
    let epub3_bytes = book.export_epub3_bytes()?;

    // Search with surrounding context snippets and <mark> highlights
