     "The Round Robin Database Tool (RRDtool) is a system to store and display
time-series data (e.g. network bandwidth, machine-room temperature, server
load average).  It stores the data in Round Robin Databases (RRDs), a very
compact way that will not expand over time.  RRDtool processes the extracted
data to enforce a certain data density, allowing for useful graphical
representation of data values.")
