3 * tcl_syscolors.d - trace Tcl program flow plus syscalls, in color.
4 *                   Written for the Tcl DTrace provider.
5 *
6 * $Id: tcl_syscolors.d 63 2007-10-04 04:34:38Z brendan $
7 *
8 * This traces activity from all Tcl processes on the system with DTrace
9 * provider support (tcl8.4.16).
10 *
11 * USAGE: tcl_syscolors.d { -p PID | -c cmd }	# hit Ctrl-C to end
12 *
13 * This watches Tcl method entries and returns, and indents child
14 * method calls.
15 *
16 * FIELDS:
17 *		C		CPU-id
18 *		PID		Process ID
19 *		TID		Thread ID
20 *		DELTA(us)	Elapsed time from previous line to this line
21 *		TYPE		Type of call (proc/cmd/syscall)
22 *		NAME		Tcl proc/cmd or syscall name
23 *
24 * WARNING: Watch the first column carefully, it prints the CPU-id. If it
25 * changes, then it is very likely that the output has been shuffled.
