I'm Jonathan Bullock; creator of JBake and Twitile, developer with a passion for the Internet, geek, gadget lover and fan of far too many sports. I occasionally give talks, take some photos and tweet every now and then.
JBake is an open source static site generator that is blog aware, designed for developers.
Supports both Markdown and HTML formatted content, has template and scripting support and can be used with CSS frameworks such as Bootstrap.
It's open source and available under a MIT License on GitHub.
It powers this site as well as JBake.org too.
It's written in Java; Freemarker is used to provide template & scripting support, MarkdownJ for Markdown support, Apache Commons for various features such as general I/O and Configuration file support and Apache Maven for dependency and build/packaging support.
