43	/** @page pg_guest_lib VirtualBox Guest Library
44	*
45	* This is a library for abstracting the additions driver interface. There are
46	* multiple versions of the library depending on the context. The main
47	* distinction is between kernel and user mode where the interfaces are very
48	* different.
49	*
50	*
51	* @section sec_guest_lib_ring0 Ring-0
52	*
53	* In ring-0 there are two version:
54	* - VBOX_LIB_VBGL_R0_BASE / VBoxGuestR0LibBase for the VBoxGuest main driver,
55	* who is responsible for managing the VMMDev virtual hardware.
56	* - VBOX_LIB_VBGL_R0 / VBoxGuestR0Lib for other (client) guest drivers.
57	*
58	*
59	* The library source code and the header have a define VBGL_VBOXGUEST, which is
60	* defined for VBoxGuest and undefined for other drivers. Drivers must choose
61	* right library in their makefiles and set VBGL_VBOXGUEST accordingly.
62	*
63	* The libraries consists of:
64	* - common code to be used by both VBoxGuest and other drivers;
65	* - VBoxGuest specific code;
66	* - code for other drivers which communicate with VBoxGuest via an IOCTL.
67	*
68	*
69	* @section sec_guest_lib_ring3 Ring-3
70	*
71	* There are more variants of the library here:
72	* - VBOX_LIB_VBGL_R3 / VBoxGuestR3Lib for programs.
73	* - VBOX_LIB_VBGL_R3_XFREE86 / VBoxGuestR3LibXFree86 for old style XFree
74	* drivers which uses special loader and or symbol resolving strategy.
75	* - VBOX_LIB_VBGL_R3_SHARED / VBoxGuestR3LibShared for shared objects / DLLs /
76	* Dylibs.
