(INSTALL-USER-DRIVER name)

Installs the driver whose name is specified as user BGI driver. The HP95LX driver should be used this way, since it is not part of the standard BGI drivers. INSTALL-USER-DRIVER establishes a link between the driver and the list of known drivers. It returns a symbol, made of name, which can then be used when calling INIT-GRAPH. The argument name is a string.
