Subject: Add NetworkManager magic for connection status autodetection.
 Defaults to

2006-01-15  Christian Persch  <chpe@cvs.gnome.org>

	* configure.ac:
	* embed/mozilla/Makefile.am:
	* embed/mozilla/mozilla-embed-single.cpp:
	* src/Makefile.am:

	Add NetworkManager magic for connection status autodetection.
	Defaults to disabled because I'm not very happy with the libnm-glib
	implementation. Oh, and it may crash on startup, too.
