Log Message:
RRDTool::OO is an object-oriented interface to Tobi Oetiker's
round robin database tool rrdtool. It uses rrdtool's RRDs module
to get access to rrdtool's shared library.

RRDTool::OO tries to marry rrdtool's database engine with the
dwimminess and whipuptitude Perl programmers take for granted.
Using RRDTool::OO abstracts away implementation details of the
RRD engine, uses easy to memorize named parameters and sets
meaningful defaults for parameters not needed in simple cases.
