static site generator written in Ruby - external filter

 Nanoc is a static site generator, fit for building anything from a small
 personal blog to a large corporate web site. It can transform content
 from one format (e.g. Haml or Markdown) into another (usually HTML) and
 lay out pages so that the site's look and feel is consistent across all
 pages.
 .
 This package contains the external filter for Nanoc, allowing one to run any
 tool to process items.
