WordPress 3.0 is coming with 2 interesting features: custom post types and (improved) custom taxonomies. These 2 features help us to create different content (not only traditional blog posts) and classify them in many ways. To list all this content in a page like an archive page, we often use the query_posts() function in a custom page template. The problem is: if the content is big (many custom posts), we might want to separate them in pages, but how to paginate the content within an archive page?
