+ * - <b>tracing/categories.c</b> This is a master/slave program where the master creates tasks, send them to the slaves.
+ * For each task received, the slave executes it and then destroys it. This program declares several tracing categories
+ * that are used to classify tasks. When the program is executed, the tracing mechanism registers the resource
+ * utilization of hosts and links according to these categories. You might want to run this program with the following
+ * parameters:
+ * --cfg=tracing:yes
+ * --cfg=tracing/categorized:yes
+ * --cfg=tracing/uncategorized:yes
+ * --cfg=viva/categorized:viva_cat.plist
+ * --cfg=viva/uncategorized:viva_uncat.plist
+ * (See \ref tracing_tracing_options for details)
