Code:
Quoting means just that, bracketing a string in quotes. This has the effect of protecting special characters in
the string from reinterpretation or expansion by the shell or shell script. (A character is "special" if it has an
interpretation other than its literal meaning, such as the wild card character -- *.)

NAME

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

       (drivers)

DESCRIPTION

       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.
