 * MS COM / XPCOM Abstraction Layer:
 * VirtualBox COM Library definitions.
 *
 * Note: This is the main header file that COM/XPCOM clients
 * include; however, it is only a wrapper around another
 * platform-dependent include file that contains the real
 * COM/XPCOM interface declarations. That other include file
 * is generated automatically at build time from
 * /src/VBox/Main/idl/VirtualBox.xidl, which contains all
 * the VirtualBox interfaces; the include file is called
 * VirtualBox.h on Windows hosts and VirtualBox_XPCOM.h
 * on Linux hosts. The build process places it in
 * out/<platform>/bin/sdk/include, from where it gets
 * included by the rest of the VirtualBox code.
