NAME

       XDRIVER - GRASS Monitor	- driver to display GRASS maps in X11 environment.

       The GRASS XDRIVER can be used to display GRASS maps in X11 environment.

Usage in details
       Variables:

		     GRASS_WIDTH
		     set the x size in pixel for the XDRIVER (default: 640)

		     GRASS_HEIGHT
		     set the y size in pixel for the XDRIVER (default: 480)

		     XDRIVER_TRUECOLOR=[TRUE|FALSE]
		     Look for a TrueColor visual (?)

		     XDRIVER_WINDOW
		     ?

		     XDRIVER_PRIVATE_CMAP
		     Private color map (?)

		     XDRIVER_LEFT
		     defines the left position of GRASS monitor (removed?)

		     XDRIVER_TOP
		     define the upper position of GRASS monitor (removed?)

   Set the XDRIVER size

       # bash shell syntax:
       export GRASS_WIDTH=xxx
       export GRASS_HEIGHT=yyy

       # c shell syntax:
       setenv GRASS_WIDTH xxx
       setenv GRASS_HEIGHT yyy
	To control the XDRIVER, use the d.mon module.

       The maximum color depth depends on the current X Server settings.
