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.
