Installation of VG:

1. Copy VG.EXE to an appropriate directory, e.g.,
	COPY VG.EXE DUA0:[VG]
2. Define a foreign command for VG in the system-wide login file, e.g., 
	VG :== $DUA0:[VG]VG
3. Install the help file:
	LIBRARY/INSERT/HELP SYS$HELP:HELPLIB VG
4. If desired, install the image (in the system startup file):
	INSTALL DUA0:[VG]VG/HEAD/OPEN
5. If desired, set up a library of include files:
	COPY *.VG DUA0:[VG]

Note that the include directory which is searched automatically by VG is
referenced by the logical name VG_DIR:.  This may be changed in the source
code or VG_DIR: may be defined to point to the directory.

VG may need to be relinked on your system if you are using devices other
than those available on MERLIN.  For example, the TALARIS driver does not
exist on MERLIN.  Note: to relink VG, issue the command:

     LINK VG,SYS$SHARE:MERLIB/LIB,INTLIB/LIB,DISSPLA/LIB,INTLIB/LIB

The MERLIB library is available on the NASA network in MRL::SHARE:[TOOLS].

The shaded fonts (SWISS, FUTURA, SERIF, LOGO) are licensed seperately and
thus may not be available on all systems.

Note that the devices used are often site-specific and therefore unresolved
external references may be generated at link time.  It is safe to ignore
these messages as long as you do not choose the missing device.
