+ * - <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)
