wmavgload 0.7.0-6.1 (amd64 binary) in ubuntu feisty

small NeXTStep-like system load average monitor
 wmavgload provides CPU load averages integrated over 5 (main window),
 30 and 60 seconds. Also, it takes very little space (64x64 square).
 .
 There's nothing in the program that makes it *require* WindowMaker,
 i.e. it works great with other window managers. But if you are looking
 for seamless integration on your desktop, wmavgload may suit your needs.
