+ *  The location of the VBoxXPCOMC.so library: /usr/lib/virtualbox/VBoxXPCOMC.so
+ *  The location of the mono library (if an alternative build is to be used): /home/ivo/mono/devtest/lib/libmono-2.0.so
+ *  To link against the mono library (if the system wide installed version is to be used): -lmono
+ *  Where to look for the VBoxXPCOMC.so library at run time: -Wl,-R,/usr/lib/virtualbox
+ *  Where to look for the mono library at run time (if non-standard): -R,/home/ivo/mono/devtest/lib/
+ *
+ * The resulting commandline may look like this:
+   gcc VBoxMono.c -o VBoxMono -lmono \
+    -I /usr/include/mono-1.0/ -I /usr/include/glib-2.0/ -I /usr/lib/glib-2.0/include/ \
