Ubuntu: sysstat chart generator utility

There is a new OSS utility that provides mechanisms for generating gnuplot charts out of the sysstat utilities (currently sar and pidstat are supported): http://code.google.com/p/yapcg/. Feel free to contribute and extend this project.
In the nearest future there shall be user guide added and UML model generated out of the code (currently it is enclosed the html api documentation - separate for each module).
