	There are lots of command-line options for cfgmaker.
	Without these, cfgmaker uses SNMP to scan the device and
	generation a stream of configuration commands which will
	cause MRTG to monitor traffic (as bytes/sec).  If you
	specify either the '--host-template' or '--if-template'
	option to refer to a file containing Perl code, you can
	control what configuration commands are generated instead
	of (or as well as) the standard ones.

	For a concrete experience of how this works, you could try
	saving the code I sent to file, and using the filename
	as the value of the '--if-template' option.  This may not
	be quite what you need, but you should get the idea.  You
	may need to use the '--host-template' option as well.

	If I'm not mistaken, this template functionality is (still)
	marked in the documentation for cfgmaker as experimental and
	subject to change or discontinuation.  This discouraged me
	for a long tome from trying it out, as I didn't want to put
	effort into building procedures on uncertain foundations.
	The functionality seems to be persisting ... 8-)

	If Perl coding is not something you feel confident about,
	you may prefer to drop sections like the following (generated
	by the code I sent) into your configuration file.

	Beware of line folding during mail-sending or -receipt!
