eBook is an example of an eXML tree based parser application. It is included in the eXML package. But eBook is more than a plain example, it is pretty much an application of its own. For example this whole web site is generated using eBook. The text and structure of this web site is stored in a XML-document. eBook takes this XML-document and some additional layout files and generates HTML pages as output.

There are several reasons why this can be usefull. I.e. eBook automatically generates the menu you can see at the left. If I want to have a new design for a site generated with ebook I need to change the layout files only. For more sophisticated changes I make changes in the source code of ebook. But I never need to touch the actual content (the XML-file). This means that eBook helps you to seperate the actual information from the layout of HTML sites. It makes it even possible to create different layout-files for different browsers, so you do not need to fidle with compatibility problems.

Currently there is not much documentation available about eBook. Have a look at the test data in the directory "/examples/test_data/ebook/input" to see how eBook works.
