What would be a python alternative to a system like nanoc?

Is there a python publishing system (have no idea whether this is an appropriate name for such a thing, but they're calling it that way) similar to nanoc? Generally, a thing which will convert a lot of markup/asciidoc files to HTML in an orderly fashion?

I know of python-markdown, but one by one page with no support for outside .css pages is not what I'm looking for?

So, is there something python based of more or less this quality?

Some website are built using Sphinx which was for documentation purposes but could be extended to a static website easily. (e.g. http://redhotchilipython.com/)
