Original commit message from CVS:
* docs/gst/gstreamer-docs.sgml:  I got tired of the reference
manual being such complete crap, that I decided to do major
hacking of it.  This checkin replaces any fine tuning that
may have been done previously, with the benefit of actually
being complete for much of the API that was changed since
0.6.  Further fine tuning will occur shortly.  (bug #134721)

<!-- ##### SECTION Title ##### -->
GstPad
<!-- ##### SECTION Short_Description ##### -->
Object contained by elements that allows links to other elements
<!-- ##### SECTION Long_Description ##### -->
<para>
A #GstElement is linked to other elements via "pads", which are extremely
light-weight generic link points.
After two pads are retrieved from an element with gst_element_get_pad(),
the pads can be link with gst_pad_link(). (For quick links,
you can also use gst_element_link(), which will make the obvious
link for you if it's straightforward.)
</para>
<para>
Pads are typically created from a #GstPadTemplate with
gst_pad_new_from_template().
</para>
<para>
Pads have #GstCaps attached to it to describe the media type they
are capable of dealing with.
gst_pad_get_caps() and gst_pad_try_set_caps() are used to
manipulate the caps of the pads.
Pads created from a pad template cannot set capabilities that are
incompatible with the pad template capabilities.
</para>
<para>
Pads without pad templates can be created with gst_pad_new(),
which takes a direction and a name as an argument. If the name is NULL,
then a guaranteed unique name will be assigned to it.
</para>
<para>
gst_pad_get_parent() will retrieve the #GstElement that owns the pad.
</para>
<para>
A #GstElement creating a pad will typically use the various
gst_pad_set_*_function() calls to register callbacks for various events
on the pads.
</para>
<para>
GstElements will use gst_pad_push() and gst_pad_pull() to push out
or pull in a buffer.
gst_pad_select() and gst_pad_selectv() are used by plugins to wait for the
first incoming buffer or event on any of the given set of pads.
</para>
<para>
To send a #GstEvent on a pad, use gst_pad_send_event().
</para>
