- * The example shows how to get info about APs visible by Wi-Fi devices
- * using libnm-glib (that wraps direct D-Bus calls).
- * The example uses dbus-glib, libnm-util and libnm-glib libraries.

- * Compile with:
- * gcc -Wall `pkg-config --libs --cflags glib-2.0 dbus-glib-1 libnm-util libnm-glib` get-ap-info-libnm-glib.c -o get-ap-info-libnm-glib
