Description:
system load monitor designed for Window Maker
wmload displays a graphical representation of the kernel/system statistics on a 64x64 miniwindow. There are three shades in the window: the light one, which corresponds to user statistics, second is the nice time statistics, and the darkest one is system statistics. . It works with other window managers, there isn't anything in the program to make it require Window Maker, except maybe the look.
