wmJupiter is a Window Maker applet which features the planet Jupiter. It allows you to keep track of the Great Red Spot and the current distance in astronomical units (AE). The four Gallileo moons (Io, Europa, Ganymede, and Calisto) are also displayed when they are near the planet.
The xfilesel program is used to copy the X selection into a file and to copy a file contents to the X selection. It acts as a bridge between applications that support selections and console applications (for example with default Midnight Commander clipboard file ~/.cedit/cooledit.clip).
xtctl is a script for setting/changing xterm properties. It can change the foreground, background, cursor, and mouse colours of an XTerm window, and the icon and background image (only known to work with Eterm). xtctl can also modify the window's title, icon name, highlight background, font, size, position, z-order (raise and lower), and iconified/restored status. There are experimental options for full and soft reset.
