.index is the template of children pages in the subtree

+ +

When a directory contains a file named .index, all files in children directories are going to use it as template.

An .index file is a normal html file, except that a few templates get replaced by the server generated content: +

+

+ +

The role of .index is thus to structure and composite in a relatively minimalistic manner the componants that make up a page of the site.
