	  help
	  This enables the Broadway backend for GDK, which provides
	  support for displaying GTK+ applications in a web browser,
	  using HTML5 and web sockets.

	  For example, to run gtk3-demo on a target which IP address is
	  192.168.0.1 and use it from a web browser, execute the
	  following commands:

	  $ broadwayd -a 192.168.0.1 -p 8080 :2 &
	  $ export GDK_BACKEND=broadway
	  $ export BROADWAY_DISPLAY=:2
	  $ gtk3-demo

	  Then open a web browser at address http://192.168.0.1:8080.
	  Javascript and web sockets should be enabled.
