The MoveIt! website (http://moveit.ros.org/) is hosted on Github Pages using Markdown format. The master branch is gh-pages as required by Github, and changes made to that branch become immediately available online.
Will install Ruby, Jekyll, build the website, and server the website on localhost:
./build_locally.sh
TODO: the currently used version of Ruby is old and needs to be updated, but Ubuntu 16.04 is holding us back.
