    NAME
         xglinfo - display & visual information  utility  for  OpenGL
         with the X Window System
    
    SYNOPSIS
         xglinfo    [-display    displayname]    [+-printDisplayInfo]
         [+-printScreenInfo]    [+-printVisualInfo]   [+-printCooked-
         VisualInfo] [+-printRawVisualInfo]
    
    
    DESCRIPTION
         Xglinfo is a utility for displaying information about  an  X
         server  supporting  the  OpenGL  extension,  especially with
         regards to visuals.  It is used to examine the  capabilities
         of  a  server,  the predefined values for various parameters
         used in communicating between clients and  the  server,  and
         the  different  types of screens and visuals that are avail-
         able. It includes the same set of information  as  xdpyinfo,
         but  is extended to display information about OpenGL visuals
         as well. In contrast to xdpyinfo  the  amount  and  form  of
         information  displayed is controllable by command line argu-
         ments.
    
         The amount of information displayed is controllable  by  the
         command  line switches. Many of these switches take either a
         '+' or a '-'. If the argument  is  preceded  by  a  '+'  the
         option  is  turned  on. If the argument is preceded by a '-'
         the option is turned off.
    
         The visual information can be printed  in  either  'raw'  or
         'cooked' form. The cooked form is the default. In the cooked
         form the visual information is analyzed and is presented  in
         user friendly form. At the same time some basic error checks
         are performed on the combinations of visual  data.  The  raw
         form just dumps the values returned for the visual.
    
         Credit is due to Jim Fulton who wrote the original  xdpyinfo
         while at MIT from which xglinfo is derived.
    
    EXAMPLE
         The following shows a sample produced by xglinfo  when  con-
         nected to display that supports an 24 plane screen. Note the
         error reporting for the  OpenGL  visuals.  The  inconsistent
         OpenGL  visuals  were  deliberately set up to illustrate the
         error checking feature.
