+.TH j_flow.d 1m "$Date:: 2007-10-03 #$" "USER COMMANDS"
+.SH NAME
+j_flow.d - snoop Java execution showing method flow using DTrace.
+.SH SYNOPSIS
+.B j_flow.d
+
+.SH DESCRIPTION
+This traces activity from all Java processes on the system with hotspot
+provider support (1.6.0) and the flag "+ExtendedDTraceProbes". eg,
+java -XX:+ExtendedDTraceProbes classfile
+
+This watches Java method entries and returns, and indents child
+method calls.
+.SH OS
+Solaris
+.SH STABILITY
+Evolving - uses the DTrace hotspot provider, which may change
+as additional features are introduced. Check Java/Readme
+to see what version these scripts are based on.
+.SH EXAMPLES
+.TP
+Default output,

+.SH FIELDS
+.TP

+TIME(us)

+PID
+Process ID

+CLASS.METHOD
+Java class and method name
+.SH LEGEND

+method return
+.SH WARNING
+Watch the first column carefully, it prints the CPU-id. If it
+changes, then it is very likely that the output has been shuffled.
+Changes in TID will appear to shuffle output, as we change from one thread
+depth to the next. See Docs/Notes/ALLjavaflow.txt for additional notes.
+.PP
+.SH DOCUMENTATION
+See the DTraceToolkit for further documentation under the
+Examples, Notes and Docs directories. The example files may be
+especially useful as they aim to demonstrate how to interpret
+the output.
+.SH EXIT
+j_flow.d will run until Ctrl-C is hit.
