/**
 * A launch group identifies a group of launch configurations by a launch
 * mode and category. The launch configuration dialog can be opened on
 * a launch group, and a launch history is maintained for each group.
 * A launch group is defined in plug-in XML via the <code>launchGroups</code>
 * extension point.
 * <p>
 * Following is an example of a launch group contribution:
 * <pre>
 * 	<extension point="org.eclipse.debug.ui.launchGroups">
 * 		<launchGroup
 * 			  id="com.example.ExampleLaunchGroupId"
 * 			  mode="run"
 * 			  label="Run"
 * 			  image="icons\run.png"
 * 		</launchGroup>
 * 	</extension>
 * </pre>
 * </p>
 * <p>
 * The debug platform defines constants for the identifiers of the launch groups
 * provided by the debug platform:
 * <ul>
 * <li>IDebugUIConstants.ID_DEBUG_LAUNCH_GROUP</li>
 * <li>IDebugUIConstants.ID_RUN_LAUNCH_GROUP</li>
 * <li>IDebugUIConstants.ID_PROFILE_LAUNCH_GROUP</li>
 * </ul>
 * </p>

 * @noimplement This interface is not intended to be implemented by clients.
 * @noextend This interface is not intended to be extended by clients.
