The entry points are a mecanism to extend the framework.
Look at the value of the entry_points keywork of the setup() call into the core/setup.py of the framework to see all the defined default entry points.
The framework knows about the following entry points:
nagare.applications: this entry point is the most often used as it registers an application to the framework.
An application can be an instance of WSGIApp, configurated with a component factory, or a direct component factory which, in this case, will be automatically wrapped into a default WSGIApp object.
nagare.publishers: these entry points defined the publishers that can be used in PublisherConfiguration#publisher-section.
nagare.sessions: there entry points defined the sessions manager that can be used in PublisherConfiguration#sessions-section.
nagare.commands: these entry points defined new administrative commands (launched with nagare-admin)
All the build-in administrative commands of the framework are defined into the core/nagare/admin directory. The class Command in admin/util.py#util.Command is the interface an administrative command must respect.
nagare.admin: these entry points defined components that will be rendered into the "Nagare Administration interface" page (launched with nagare-admin serve admin). See the core/nagare/admin/interface/info.py and core/nagare/admin/interface/applications.py files.
