MulleWeb is a small Web library collection written on top of the MulleFoundation.
It contains amongst other functionality a HTTP server and a HTTP client library and support for JSON. It is experimental at this stage. Everything taken together should enable your to write a jekyll clone fairly quickly.
MulleScion is a template engine system like Twig for Objective-C, that can be seamlessly embedded into HTML.
See mulle-web-developer for install instructions.
The mulle-scion wiki contains the documentation, that is a copy of what is served by mulle-scion.
