+ * py_syscalls.d - count Python function calls and syscalls using DTrace.
+ *                 Written for the Python DTrace provider.
+ *
+ * $Id: py_syscalls.d 25 2007-09-12 09:51:58Z brendan $
+ *
+ * USAGE: py_syscalls.d { -p PID | -c cmd }	# hit Ctrl-C to end
+ *
+ * FIELDS:
+ *		FILE		Filename of the Python program
+ *		TYPE		Type of call (func/syscall)
+ *		NAME		Name of call
+ *		COUNT		Number of calls during sample
+ *
+ * Filename and function names are printed if available.
+ * The filename for syscalls may be printed as "python", if the program
+ * was invoked using the form "python filename" rather than running the
+ * program with an interpreter line.
