54	/** @page pg_guest_lib VirtualBox Guest Library
55	*
56	* This is a library for abstracting the additions driver interface. There are
57	* multiple versions of the library depending on the context. The main
58	* distinction is between kernel and user mode where the interfaces are very
59	* different.
60	*
61	*
62	* @section sec_guest_lib_ring0 Ring-0
63	*
64	* In ring-0 there are two version:
65	* - VBOX_LIB_VBGL_R0_BASE / VBoxGuestR0LibBase for the VBoxGuest main driver,
66	* who is responsible for managing the VMMDev virtual hardware.
67	* - VBOX_LIB_VBGL_R0 / VBoxGuestR0Lib for other (client) guest drivers.
68	*
69	*
70	* The library source code and the header have a define VBGL_VBOXGUEST, which is
71	* defined for VBoxGuest and undefined for other drivers. Drivers must choose
72	* right library in their makefiles and set VBGL_VBOXGUEST accordingly.
73	*
74	* The libraries consists of:
75	* - common code to be used by both VBoxGuest and other drivers;
76	* - VBoxGuest specific code;
77	* - code for other drivers which communicate with VBoxGuest via an IOCTL.
78	*
79	*
80	* @section sec_guest_lib_ring3 Ring-3
81	*
82	* There are more variants of the library here:
83	* - VBOX_LIB_VBGL_R3 / VBoxGuestR3Lib for programs.
84	* - VBOX_LIB_VBGL_R3_XFREE86 / VBoxGuestR3LibXFree86 for old style XFree
85	* drivers which uses special loader and or symbol resolving strategy.
86	* - VBOX_LIB_VBGL_R3_SHARED / VBoxGuestR3LibShared for shared objects / DLLs /
87	* Dylibs.
