- * \brief The isc_quota_t object is a simple helper object for implementing
- * quotas on things like the number of simultaneous connections to
- * a server.  It keeps track of the amount of quota in use, and
- * encapsulates the locking necessary to allow multiple tasks to
- * share a quota.
+ * \brief The isc_counter_t object is a simplified version of the
+ * isc_quota_t object; it tracks the consumption of limited
+ * resources, returning an error condition when the quota is
+ * exceeded.  However, unlike isc_quota_t, attaching and detaching
+ * from a counter object does not increment or decrement the counter.
