Content Providers

Content providers are indivisible content displays or widgets - the providers of content and structure for complete components (e.g. a post) that can be included as part of an overall page (e.g. the topic display page).

Most Content Providers are declared in an egg's configure.zcml to have a name, a class, a template, and maybe a factory or adaptor. Content Providers are included on pages by using the tal:replace or tal:content tags and the structure

While quite common in GroupServer, these are mostly being phased out in favor of the more flexible Viewlets and Viewlet Managers.
