The "Xop" package provides Tcl/Tk with access to various low-level X window system functions. Its capabilities include:
* The ability to query arbitrary windows on Tk's display
* Access to and control of X cut buffers
* Bell frequency, volume, and duration control
* Access to X drawables, including dumping their contents to Tk images
* Querying and manipulation of the X event queue
* Reading of window-manager-related window properties
* Colormap control
These facilities are provided via the "xop" tcl command. The intended purpose of the Xop package is to provide certain low-level X11 facilities required by window managers, but the package need not be used in that way.
