33	* PURPOSE OF THIS SAMPLE PROGRAM
34	* ------------------------------
35	*
36	* This sample program is intended to demonstrate the minimal code necessary
37	* to use VirtualBox XPCOM API for learning puroses only. The program uses
38	* pure XPCOM and doesn't have any extra dependencies to let you better
39	* understand what is going on when a client talks to the VirtualBox core
40	* using the XPCOM framework.
41	*
42	* However, if you want to write a real application, it is highly recommended
43	* to use our MS COM XPCOM Glue library and helper C++ classes. This way, you
44	* will get at least the following benefits:
45	*
46	* a) better portability: both the MS COM (used on Windows) and XPCOM (used
47	* everywhere else) VirtualBox client application from the same source code
48	* (including common smart C++ templates for automatic interface pointer
49	* reference counter and string data management);
50	* b) simpler XPCOM initialization and shutdown (only a single method call
51	* that does everything right).
52	*
53	* Currently, there is no separate sample program that uses the VirtualBox MS
54	* COM XPCOM Glue library. Please refer to the sources of stock VirtualBox
55	* applications such as the VirtualBox GUI frontend or the VBoxManage command
56	* line frontend.
57	*
58	*
59	* RUNNING THIS SAMPLE PROGRAM
60	* ---------------------------
61	*
62	* This sample program needs to know where the VirtualBox core files reside
63	* and where to search for VirtualBox shared libraries. Therefore, you need to
64	* use the following (or similar) command to execute it:
65	*
66	* $ env VBOX_XPCOM_HOME=../../.. LD_LIBRARY_PATH=../../.. ./tstVBoxAPIXPCOM
67	*
68	* The above command assumes that VBoxRT.so, VBoxXPCOM.so and others reside in
69	* the directory ../../..
