/*
* tcl_syscolors.d - trace Tcl program flow plus syscalls, in color.
* Written for the Tcl DTrace provider.
*
* $Id: tcl_syscolors.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_syscolors.d { -p PID | -c cmd } # hit Ctrl-C to end
*
* This watches Tcl method entries and returns, and indents child
* method calls.
*
* FIELDS:
* C CPU-id
* PID Process ID
* TID Thread ID
* DELTA(us) Elapsed time from previous line to this line
* TYPE Type of call (proc/cmd/syscall)
* NAME Tcl proc/cmd or syscall name
*
* 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.
