title: Amazon KF8 file format specifications
body: <p>I want to generate KF8 without going through the conversion process (My Content --> Epub/Html --> KindleGen/Calibre/Other tool), as I need more control over kf8 file generation. 
  The <a href="http://kindlegen.s3.amazonaws.com/AmazonKindlePublishingGuidelines.pdf" rel="nofollow noreferrer">guidelines document</a> &amp; the <a href="http://www.amazon.com/gp/feature.html?docId=1000729511" rel="nofollow noreferrer">format overview</a> can't fulfill the need for specifications.</p>
  
  <p><strong>Are official KF8 file format specs available?</strong> 
  Although I have found some information on links such as <a href="http://wiki.mobileread.com/wiki/KF8#The_Format" rel="nofollow noreferrer">http://wiki.mobileread.com/wiki/KF8#The_Format</a>, but want to avoid relying on unofficial/reverse-engineered stuff.</p>
