Low resource Window manager ideal for older PCs. It uses a minimum of external libraries, thus very little memory, includes virtual screens, menubar and root-menu popup.

JWM is a window manager for the X11 Window System. JWM is written in C and uses only Xlib and (optionally) the shape extension and libXpm. It can support some MWM, GNOME, and WM Spec hints. The menu configuration files are managed in XML format.

This JWM package is built with support for the full suite of supported image formats, including JPEG, PNG, SVG and XPM; as well as Xinerama and Xrender extensions, and FreeType-based font rendering.

Compared to other light WM, like FVWM or Openbox, the Jwm consumes considerably less memory while providing the same functionality.
