+/**
+ * @class ACE_Timeprobe
+ *
+ * @brief This class is used to instrument code.  This is accomplished
+ * by inserting time probes at different location in the code.
+ * ACE_Timeprobe then measures the time difference between two
+ * time probes.
+ *
+ * This class provides a lightweight implementation for
+ * measuring the time required to execute code between two time
+ * probes.  When a time probe executes, it records the time, the
+ * id of the calling thread, and an event description.  The
+ * event description can either be an unsigned long or a string
+ * (char *). If string are used, care must be taken cause only
+ * pointer copies are done and the string data is *not* copied.
+ * The recorded time probes can then be printed by calling
+ * <print_times>.  If you have used unsigned longs as event
+ * descriptions in any of your time probes, you must have
+ * provided an event description table that maps the unsigned
+ * longs to readable strings.  This map is a simple array of
+ * strings, and the event number is used as the index into the
+ * array when looking for the event description.  If you have
+ * only used strings for the event description, this map is not
+ * necessary.
+ * Multiple maps can also be used to chunk up the time probes.
+ * Each one can be added by calling <event_descriptions>.
+ * Different tables are used internally by consulting the
+ * minimum_id for each table.  It is up to the user to make sure
+ * that multiple tables do not share the same event id range.
