9 * - <b>Setting Categories: trace-categories/trace-categories.c</b>. This example declares several tracing categories
10 * that are used to classify tasks. When the program is executed, the tracing mechanism registers the resource
11 * utilization of hosts and links according to these categories. You might want to run this program with the following
12 * options: <i>--cfg=tracing:yes</i>, <i>--cfg=tracing/categorized:yes</i>, <i>--cfg=tracing/uncategorized:yes</i>,
13 * <i>--cfg=viva/categorized:viva_cat.plist</i>, and <i>--cfg=viva/uncategorized:viva_uncat.plist</i>.
