60	*
61	* This is a library for abstracting the additions driver interface. There are
62	* multiple versions of the library depending on the context. The main
63	* distinction is between kernel and user mode where the interfaces are very
64	* different.
65	*
66	*
67	* @section sec_guest_lib_ring0 Ring-0
68	*
69	* In ring-0 there are two version:
70	* - VBOX_LIB_VBGL_R0_BASE / VBoxGuestR0LibBase for the VBoxGuest main driver,
71	* who is responsible for managing the VMMDev virtual hardware.
72	* - VBOX_LIB_VBGL_R0 / VBoxGuestR0Lib for other (client) guest drivers.
73	*
74	*
75	* The library source code and the header have a define VBGL_VBOXGUEST, which is
76	* defined for VBoxGuest and undefined for other drivers. Drivers must choose
77	* right library in their makefiles and set VBGL_VBOXGUEST accordingly.
78	*
79	* The libraries consists of:
80	* - common code to be used by both VBoxGuest and other drivers;
81	* - VBoxGuest specific code;
82	* - code for other drivers which communicate with VBoxGuest via an IOCTL.
83	*
84	*
85	* @section sec_guest_lib_ring3 Ring-3
86	*
87	* There are more variants of the library here:
88	* - VBOX_LIB_VBGL_R3 / VBoxGuestR3Lib for programs.
89	* - VBOX_LIB_VBGL_R3_XFREE86 / VBoxGuestR3LibXFree86 for old style XFree
90	* drivers which uses special loader and or symbol resolving strategy.
91	* - VBOX_LIB_VBGL_R3_SHARED / VBoxGuestR3LibShared for shared objects / DLLs /
92	* Dylibs.
