Subject: [rrd-users] perl script that uses RPN exactly like rrdtool CDEF

I was just wondering if anyone has a perl script that can take RPN math
expressions and use them like rrdtool. 
I am looking for a way to use a CDEF expression and use it outside of
rrdtool. For example, 
push @args, "CDEF:inavbyte=8,ifInOctets,ifSpeed,/,*" for rrdtool could
be
used in a script to get the same results without using rrdtool graph
function:
use RPN;
$utilization = rpn->(8,ifInOctets,ifSpeed,/,*);
 
Any thoughts?
Thanks in advance,
Rob
