+WARNING! This file format is under development, and is subject to
+change without notice.
+
+This file contains the following types of records:
+
+THREAD START
+THREAD END mark the lifetime of Java threads
+
+TRACE represents a Java stack trace. Each trace consists
+ of a series of stack frames. Other records refer to
+ TRACEs to identify (1) where object allocations have
+ taken place, (2) the frames in which GC roots were
+ found, and (3) frequently executed methods.
+
+HEAP DUMP is a complete snapshot of all live objects in the Java
+ heap. Following distinctions are made:
+
+ ROOT root set as determined by GC
+ CLS classes
+ OBJ instances
+ ARR arrays
+
+SITES is a sorted list of allocation sites. This identifies
+ the most heavily allocated object types, and the TRACE
+ at which those allocations occurred.
+
+CPU SAMPLES is a statistical profile of program execution. The VM
+ periodically samples all running threads, and assigns
+ a quantum to active TRACEs in those threads. Entries
+ in this record are TRACEs ranked by the percentage of
+ total quanta they consumed; top-ranked TRACEs are
+ typically hot spots in the program.
+
+CPU TIME is a profile of program execution obtained by measuring
+ the time spent in individual methods (excluding the time
+ spent in callees), as well as by counting the number of
+ times each method is called. Entries in this record are
+ TRACEs ranked by the percentage of total CPU time. The
+ "count" field indicates the number of times each TRACE
+ is invoked.
+
+MONITOR TIME is a profile of monitor contention obtained by measuring
+ the time spent by a thread waiting to enter a monitor.
+ Entries in this record are TRACEs ranked by the percentage
+ of total monitor contention time and a brief description
+ of the monitor. The "count" field indicates the number of
+ times the monitor was contended at that TRACE.
+
+MONITOR DUMP is a complete snapshot of all the monitors and threads in
+ the System.
+
+HEAP DUMP, SITES, CPU SAMPLES|TIME and MONITOR DUMP|TIME records are generated
+at program exit. They can also be obtained during program execution by typing
+Ctrl-\ (on Solaris) or by typing Ctrl-Break (on Win32).
