Content Plugins are preloaded by Bricklayer. They get called by Bricklayer automatically during the publish method. These plugins are expected to act as filters for whatever gets published. Use them sparingly. Running too many of these could slow your app down significantly. Often these plugins will need to take a look at the environment and publish type to decide if they should run at all. The content to publish will be the first argument passed to these.
