+ * py_flowinfo.d - snoop Python function flow with info using DTrace.
+ * Written for the Python DTrace provider.
+ *
+ * $Id: py_flowinfo.d 41 2007-09-17 02:20:10Z brendan $
+ *
+ * This traces activity from all Python programs on the system that are
+ * running with Python provider support.
+ *
+ * USAGE: py_flowinfo.d # hit Ctrl-C to end
+ *
+ * FIELDS:
+ * C CPU-id
+ * PID Process ID
+ * DELTA(us) Elapsed time from previous line to this line
+ * FILE Filename of the Python program
+ * LINE Line number of filename
+ * TYPE Type of call (func)
+ * FUNC Python function
+ *
+ * LEGEND:
+ * -> function entry
+ * <- function return
+ *
+ * Filename and function names are printed if available.
+ *
+ * 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.
