| /** |
| * Override this class to provide automatic detection for a framework by analyzing files in the project. Use this extension only if the |
| * framework requires some additional configuration which need to be performed by an user (e.g. specifying path to a SDK) and stored in |
| * the project files. If support for the framework can be provided without user interaction it is preferable to enable framework specific |
| * highlighting/completion and show framework related actions silently so this extension shouldn't be used in such cases. |
| * |
| * <p> |
| * Frameworks detectors are used when a new project is created using 'Create Project from sources' option and when files are copied/created |
| * in an opened project. In both cases a notification is shown to user allowing she to accept or ignore detected frameworks. |
| * </p> |
| * The implementation should be registered in your {@code plugin.xml}: |
| * <pre> |
| * <extensions defaultExtensionNs="com.intellij"> |
| * <framework.detector implementation="qualified-class-name"/> |
| * </extensions> |
