- * @section msg_ex_tracing_user_variables Tracing user variables
- * The tracing mechanism of SimGrid also allows to associate user variables to resources described in the platform file.
- * The following examples illustrate this feature. They have to be run with the <i>--cfg=tracing:yes</i> and
- * <i>--cfg=tracing/platform:yes</i> options.
- *
- * - <b>Hosts: trace-user-variables/trace-user-variables.c</b>. This example shows how user defined variables can be
- * associated to an host and how to manage the tracing of their evolution.
