Not really.  It is a pseudo script.  Its only purpose is to show you
what to do, in English.  You have to translate it into your favorite
computer language.

Do this step by step.  First start using the snmpget command.  Make
sure you get valid output.  Use command line options/flags to the
snmpget command so that you get only the resulting number.  If
necessary use a filter (such as awk).

Next step is to put this output in variable "in" and "out".

When this works you should be able to generate the proper command
for rrdtool.  When you are able to echo the entire command to screen
you should also be able to actually execute this command.
