- * \brief Graphical plugin for showing events.
- *
- * This plugin lists all the events contained in the current time interval
- * in a list.
- *
- * 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 viewer.h'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 lttvwindow.
- *
- * Authors : Mathieu Desnoyers and XangXiu Yang, June to December 2003
- * Inspired from original LTT, made by Karim Yaghmour
- *
- * Mostly rewritten by Mathieu Desnoyers, August 2005.
