GEOMETRY SPECIFICATIONS
One of the advantages of using window systems instead of hardwired ter-
minals is that applications don't have to be restricted to a particular
size or location on the screen. Although the layout of windows on a
display is controlled by the window manager that the user is running
(described below), most X programs accept a command line argument of
the form -geometry WIDTHxHEIGHT+XOFF+YOFF (where WIDTH, HEIGHT, XOFF,
and YOFF are numbers) for specifying a preferred size and location for
this application's main window.
