- * - <b>tracing/link_srcdst_user_variables.c</b>: This program demonstrates how to
- * trace user variables associated to the links of the platform file. Instead of
- * providing the name of the link to update one of its variable, this example shows
- * how to provide two hosts as parameter (source and destination, use their names as
- * defined in the platform file). The tracing mechanism will get the route between
- * these two hosts, if there is one defined in the platform file, and update the variable
- * of all the links of that route to the value provided.
- * You might want to run this program with the following parameters:
- * --cfg=tracing:yes
- * --cfg=tracing/platform:yes
- * (See \ref tracing_tracing_options for details)
