distribusi is a content management system for the web that produces static
index pages based on folders in the files system. It is inspired by the
automatic index functions featured in several popular web servers.
distribusi works by traversing the file system and directory hierarchy to
automatically list all the files in the directory, detect the file types
and providing them with relevant html classes and tags for easy styling.
