/*
* rb_syscolors.d - trace Ruby method flow plus syscalls, in color.
* Written for the Ruby DTrace provider.
*
* $Id: rb_syscolors.d 27 2007-09-13 09:26:01Z brendan $
*
* USAGE: rb_syscolors.d { -p PID | -c cmd } # hit Ctrl-C to end
*
* This watches Ruby method entries and returns, and indents child
* function calls.
*
* FIELDS:
* C CPU-id
* PID Process ID
* DELTA(us) Elapsed time from previous line to this line
* FILE Filename of the Ruby program
* LINE Line number of filename
* TYPE Type of call (method/line/syscall)
* NAME Ruby method or syscall name
*
* Filename and method 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.
