DESCRIPTION
       The xzoom program displays  in its window a magnified area of the X11 display.	The  user
       can   interactively   change  the  zoomed area, the window size, magnification (optionally
       different magnification for X and Y axes) or rotate  or	mirror	the image.

OPTIONS
       -display displayname
		      The name of the display to use (not very useful).

       -mag mag [ mag ]
		      What  magnification  to  use. If two  number  arguments  are  supplied  the
		      first  is used  for  X  magniications and the second is used for Y magnifi-
		      cation.  Magnification should be greater than 0.

       -x	      Mirror horizontally.

       -y	      Mirror vertically.

       -xy	      Exchange X and Y axes  before  any  magnification  is performed.

       -geometry geometry
		      Size and position xzoom's window.

       -source geometry
		      Size  and  position  the initial	source	area  which  is  magnified.   The
		      dimensions  of  this  area  are  multiplied by the magnification to get the
		      size of xzoom's window. If these dimensions are given separately (by use of
		      -geometry ) then an error is reported.

       -mouse	      Interactively update the magnified area,by moving the mouse pointer.

       -multi	      Used when the display specified is a multi-visual.
