XML-Grammar-Fiction is a Perl package that provides processors for lightweight markup languages and corresponding XML grammars for writing prose (e.g. stories, novels, and novellas) as well as screenplays. The XML grammars can in turn be translated to XHTML and DocBook/XML. XML-Grammar-Fiction currently offers only very basic functionality, but has good support for UTF-8 and allows one to write bidirectional texts conveniently. It is still under development and may exhibit some quirks.
Fairy Books lets you create digital versions of all your child's favorite stories, or even create entirely new stories together. You can take pictures of existing book pages or import pictures from the gallery, then record the story using your own voice, the way you want it to be told. Fairy Books is the perfect storytelling companion for when you can't read to your child yourself.
