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