+/*! \file guiEvents.c
+ * \brief Graphical plugin for showing events.
+ *
+ * This plugin adds a Events Viewer functionnality to Linux TraceToolkit
+ * GUI when this plugin is loaded. The init and destroy functions add the
+ * viewer's insertion menu item and toolbar icon by calling gtkTraceSet's
+ * API functions. Then, when a viewer's object is created, the constructor
+ * creates ans register through API functions what is needed to interact
+ * with the TraceSet window.
+ *
+ * This plugin uses the gdk library to draw the events and gtk to interact
+ * with the user.
+ *
