TheMonarch.SyntaxHighlighter 0.0.2 Download Adds source code syntax highlighting to Orchard Blog posts.

This module uses Google code prettify to add syntax highlighting to Orchard Blog posts. Choose from several themes bundled from the Admin UI. Google code prettify automatically detects most languages.

This is a nice pair with TinyMceDeluxe, which will allow you to paste code snippets when creating/editing blog posts.
