- * - <b>energy-ptask/energy-ptask.c</b>: Demonstrates the use of @ref MSG_parallel_task_create, to create special
- *   tasks that run on several hosts at the same time. The resulting simulations are very close to what can be
- *   achieved in @ref SD_API, but still allows one to use the other features of MSG (it'd be cool to be able to mix
- *   interfaces, but it's not possible ATM).
