Original commit message from CVS:
Re- set up the gtk-doc system.  I'd managed to mutilate it a while back,
but now it's fixed.  I'll put a copy of the HTML output somewhere on the
website tonight.

In order to actually generate the docs, you'll have to install all the
DocBook tools, as well as gtk-doc from GNOME cvs.  (see
http://developer.gnome.org/arch/doc/tools.html)

Notes (I'll codify these some day):

- Don't believe the Gnome page, always edit the SOURCES when documenting a
given function, never the tmpl file.
- I'll be re-arranging things a lot, but gtk-doc is smart enough to merge
any changes to the tmpl file.  However, gtk-doc's merge and CVS's diff are
two entirely separate animals.  We should probably have a virtual mutex on
the entire docs/gst/ directory, over and above what CVS does.
- I'm going to try to end up with a book set (docbook terms), where
docs/gst/ is only one book.  There'd be another called docs/manual/, and
another docs/plugins/, etc.  If you have any comments as to how these
should be done, gstreamer-devel is the place.
