Ruhoh is a static site generator made for publishing content on the Internet. It's similar to jekyll, nanoc, and others.
A static site is a website with no moving parts: no dependencies, no database, no code execution, no admin panel. This is different from a "web application" which requires many layers of software.
Publish anywhere by "compiling" your website and hosting the contents on nearly any web-host on the planet. Ruhoh also supports automatic hosting so you don't have to worry about finding or setting up a web-host.
