A highly configurable, very gaudy system load meter

 MGM is the Moaning Goat Meter, a system load monitor along the lines
 of procmeter3 but much prettier (and with a much higher resource usage).
 It's written in Perl/Tk, uses a nice antialiased Helvetica font, is
 configurable with X resources, and can have a larger memory footprint than
 Emacs.
