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