I've just launched DocBoot, a web-based tool to convert your Scrivener and Microsoft Word documents into a website or online ebook. Your document is automatically converted into a sleek, navigable, mini-website. A table of contents is generated from your headings allowing users to quickly navigate your site. Perfect for documentation, ebooks, and other long-form content that you want to offer online.
Give it a try at http://docbook.com.
Or if you want, you can download a command line version of the tool from github.
