--------------------- ---------------------
Structure detection involves calibre trying its best to detect structural elements in the input document, when they are not properly specified. For example, chapters, page breaks, headers, footers, etc. As you can imagine, this process varies widely from book to book. Fortunately, calibre has very powerful options to control this. With power comes complexity, but if once you take the time to learn the complexity, you will find it well worth the effort.
