/** @page pg_guest_lib  VirtualBox Guest Library
 *
 * This is a library for abstracting the additions driver interface. There are
 * multiple versions of the library depending on the context. The main
 * distinction is between kernel and user mode where the interfaces are very
 * different.
 *
 *
 * @section sec_guest_lib_ring0     Ring-0
 *
 * In ring-0 there are two version:
 *  - VBOX_LIB_VBGL_R0_BASE / VBoxGuestR0LibBase for the VBoxGuest main driver,
 *    who is responsible for managing the VMMDev virtual hardware.
 *  - VBOX_LIB_VBGL_R0 / VBoxGuestR0Lib for other (client) guest drivers.
 *
 *
 * The library source code and the header have a define VBGL_VBOXGUEST, which is
 * defined for VBoxGuest and undefined for other drivers. Drivers must choose
 * right library in their makefiles and set VBGL_VBOXGUEST accordingly.
 *
 * The libraries consists of:
 *  - common code to be used by both VBoxGuest and other drivers;
 *  - VBoxGuest specific code;
 *  - code for other drivers which communicate with VBoxGuest via an IOCTL.
 *
 *
 * @section sec_guest_lib_ring3     Ring-3
 *
 * There are more variants of the library here:
 *  - VBOX_LIB_VBGL_R3 / VBoxGuestR3Lib for programs.
 *  - VBOX_LIB_VBGL_R3_XFREE86 / VBoxGuestR3LibXFree86 for old style XFree
 *    drivers which uses special loader and or symbol resolving strategy.
 *  - VBOX_LIB_VBGL_R3_SHARED / VBoxGuestR3LibShared for shared objects / DLLs /
 *    Dylibs.
