In the meantime I have added a button to generate the toc.xhtml:

We haven't explained the buttons yet:

  1. The button toc.xhtml generates the file "toc.xhtml" in the field on the left.
  2. The button toc.ncx generates the file "toc.ncx" in the field on the left.
  3. The button content.opf generates the file "content.opf" in the field on the left.
  4. The button Save saves whatever has been generated in the folder "OEBPS".
  5. The button create batch creates a batch file using the name in the text box "Book's name" and saves it directly in the folder "EBook".

All the metas that you enter are used to generate the head of the file "content.opf". Now all that you have to do is go to "EBook" and hit "make_ebook.bat" and then "check_ebook.bat".
