AVAILABILITY
       The GNOME magnifier (gnome-mag) provides a command-line  interface  for
       standalone use, although its primary goal is to provide a set of magni‐
       fication services for use by other client  applications  and  assistive
       technologies, like Gnopernicus, Orca or LSR.

       This magnifier is compatible with operating systems using X Window Sys‐
       tem, although the magnifier will have a better  performance  and  func‐
       tionality when the Damage and Fixes extensions are present.

DESCRIPTION
       A  desktop  screen magnifier.  If present, the Region Of Interest (ROI)
       for the magnifier can be driven by a screen reader  via  the  Assistive
       Technology Service Provider Interface (ATSPI); otherwise, the magnifier
       will be centered to the pointer position.
