+ * Contrast this example with add-connection-dbus-glib.c, which is a bit lower

+ * because libnm-glib handles much of the low-level stuff for you.
+ *
+ * Compile with:
+ *   gcc -Wall `pkg-config --libs --cflags glib-2.0 dbus-glib-1 libnm-util` add-connection-libnm-glib.c -o add-connection-libnm-glib
