Starting with version 1.6, pandoc can produce output in the EPUB electronic book format. EPUB books can be viewed on iPads, Nooks, and other electronic book readers, including many smart phones. (They can also be converted to Kindle books using the GUI only KindlePreviewer on Windows and Mac OSX. KindleGen – which offers a command line interface and supports Linux, Mac OSX and Windows – has been deprecated, but binaries can still be found on the internet.)
