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.

This package contains header files and libraries used to develop software
that uses RRDs.
