38	/** @page pg_guest_lib VirtualBox Guest Library
39	*
40	* This is a library for abstracting the additions driver interface. There are
41	* multiple versions of the library depending on the context. The main
42	* distinction is between kernel and user mode where the interfaces are very
43	* different.
44	*
45	*
46	* @section sec_guest_lib_ring0 Ring-0
47	*
48	* In ring-0 there are two version:
49	* - VBOX_LIB_VBGL_R0_BASE / VBoxGuestR0LibBase for the VBoxGuest main driver,
50	* who is responsible for managing the VMMDev virtual hardware.
51	* - VBOX_LIB_VBGL_R0 / VBoxGuestR0Lib for other (client) guest drivers.
52	*
53	*
54	* The library source code and the header have a define VBGL_VBOXGUEST, which is
55	* defined for VBoxGuest and undefined for other drivers. Drivers must choose
56	* right library in their makefiles and set VBGL_VBOXGUEST accordingly.
57	*
58	* The libraries consists of:
59	* - common code to be used by both VBoxGuest and other drivers;
60	* - VBoxGuest specific code;
61	* - code for other drivers which communicate with VBoxGuest via an IOCTL.
62	*
63	*
64	* @section sec_guest_lib_ring3 Ring-3
65	*
66	* There are more variants of the library here:
67	* - VBOX_LIB_VBGL_R3 / VBoxGuestR3Lib for programs.
68	* - VBOX_LIB_VBGL_R3_XFREE86 / VBoxGuestR3LibXFree86 for old style XFree
69	* drivers which uses special loader and or symbol resolving strategy.
70	* - VBOX_LIB_VBGL_R3_SHARED / VBoxGuestR3LibShared for shared objects / DLLs /
71	* Dylibs.
