Project features determine what services a project will provide after being activated. Project features can have non-circular dependencies on other project features. Activating a project is equal to configuring all of its features. The feature dependencies will determine the order of configuration through topological sorting. Project features are defined using the org.simantics.project.feature Eclipse extension-point. See its documentation for more information. A project is essentially a set of project features. Project features are responsible for configuring the project and contributing services to it. See org.simantics.project.IProject for the run-time representation of an existing project, either activated or deactivated. See org.simantics.project.Projects for project management utilities.
