+%description cached
+rrdcached is a daemon that receives updates to existing RRD files,
+accumulates them and, if enough have been received or a defined time has
+passed, writes the updates to the RRD file. The daemon was written with
+big setups in mind which usually runs into I/O related problems. This
+daemon was written to alleviate these problems.
