+ * tcl_flowtime.d - snoop Tcl execution showing procedure flow and delta times.
+ * Written for the Tcl DTrace provider.
+ *
+ * $Id: tcl_flowtime.d 63 2007-10-04 04:34:38Z brendan $
+ *
+ * This traces activity from all Tcl processes on the system with DTrace
+ * provider support (tcl8.4.16).
+ *
+ * USAGE: tcl_flowtime.d # hit Ctrl-C to end
+ *
+ * This watches Tcl method entries and returns, and indents child
+ * method calls.
+ *
+ * FIELDS:
+ * C CPU-id
+ * PID Process ID
+ * TIME(us) Time since boot, us
+ * DELTA(us) Elapsed time from previous line to this line
+ * CALL Tcl command or procedure name
+ *
+ * LEGEND:
+ * -> procedure entry
+ * <- procedure return
+ * > command entry
+ * < command return
+ *
+ * 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.
