This book is mostly generated by Jeszra from source code. The individual back ends and parsers are presented as individual DocBook refentry manual pages. The manual pages show the signature, the commentary and who and how the function is being used inside of other modules.

The first chapters (Languages and Models, Embedding Jeszra) provide a short introduction, covering terminology and the various states of programming language support and models.

Chapter Embedding Jeszra deals with the integration of Jeszra in other applications. It also explains in detail how Jeszra uses Goreedit for editing itself. The self-edit mode in Jeszra makes it possible to copy and paste every element, seen in Jeszra, in your own project.
