/** \brief set a configuration variable
- *
- * Currently existing configuation variable:
- * - surf_workstation_model (string): Model of workstation to use.
- * Possible values (defaults to "KCCFLN05"):
- * - "CLM03": realistic TCP behavior + basic CPU model (see [CML03 at CCGrid03]) + support for parallel tasks
- * - "KCCFLN05": realistic TCP behavior + basic CPU model (see [CML03 at CCGrid03]) + failure handling + interference between communications and computations if precised in the platform file.
- *
+ *
+ * Do --help on any simgrid binary to see the list of currently existing configuration variables
+ *
* Example:
- * MSG_config("surf_workstation_model","KCCFLN05");
+ * MSG_config("workstation/model","KCCFLN05");
