== cover ==
A cover is essentially an image, either a raster image (jpg or png) or an SVG, however it is safer to opt for a raster.

Within the ''package document''(.opf), the cover is declared both within the manifest, as item with '''properties="cover-image"''', so that the reading systems identify the image in question as the cover of the ePub.
 <item id="cover-img" href="cover.jpg" media-type="image/jpeg" properties="cover-image"/>

If you want the cover to also appear as the first content the reader sees when she start the book, make sure to include a ''content document'' that includes the image:
 
<source lang="xml">
