-# ETAP The Event Trace Analysis Package enables user-level tasks to monitor
-# and analyze kernel events. ETAP supports three modes of tracing:
-#
-# 1. General event tracing: ETAP_EVENT_MONITOR
-# 2. Monitored lock tracing: ETAP_LOCK_MONITOR
-# 3. Cumulative lock tracing: ETAP_LOCK_ACCUMULATE
-#
-# Each of these trace modes are mutually exclusive.
-#
-# CONFIGURING ETAP: To enable the trace package, the ETAP switch
-# along with *ONE* ETAP trace mode is selected. The selected ETAP
-# mode determines the level of instrumentation built into the kernel.
-# Mode 1 configures event probes through-out the system. Modes 2 & 3
-# add instumentation to the kernel lock mechanisms.
-#
-# ETAP (and all its trace modes) is mutually exclusive with the
-# MACH_LDEBUG option. It is assumed that general lock debugging is
-# completed before gathering event information.
-#
-# ETAP functionality is normally only enabled for event profiling and
-# performance studies. Event tracing should not be enabled for release
-# configurations, as the code size and performance impact of these
-# options are significant.
