Original commit message from CVS:
* docs/manual/appendix-integration.xml:
Update GNOME integration section to use gst_init_get_option_group()
instead of the old popt stuff (#322911). Also, GNOME applications
should  now use gconf*sink and gconf*src instead of the old gconf
helper lib we had.

<function>gst_init ()</function> to do the same for GStreamer.
This would mean that only one of the two can parse command-line
options. To work around this issue, &GStreamer; can provide a
<classname>poptOption</classname> array which can be passed to
<function>gnome_program_init ()</function>.
GLib <classname>GOptionGroup</classname> which can be passed to
<function>gnome_program_init ()</function>. The following
example requires Gnome-2.14 or newer (previous libgnome versions
do not support command line parsing via GOption yet but use the
now deprecated popt)

GNOME stores the default video and audio sources and sinks in GConf.
&GStreamer; provides a small utility library that can be used to
get the elements from the registry using functions such as
<function>gst_gconf_get_default_video_sink ()</function>. See the
header file (<filename>gst/gconf/gconf.h</filename>) for details.
All GNOME applications are recommended to use those variables.
&GStreamer; provides a number of elements that create audio and
video sources and sinks directly based on those GConf settings.
Those elements are: gconfaudiosink, gconfvideosink, gconfaudiosrc
and gconfvideosrc. You can create them with
<function>gst_element_factory_make ()</function> and use them
directly just like you would use any other source or sink element.
All GNOME applications are recommended to use those elements.
