I explained this to Jono on IRC, but I suppose I should do it here too.
Right now we use python's optparse module to parse the args for us. We 
actually don't need to use this module at all because GObject has its 
own thing called GOption. This is used my Gtk, Gstreamer, etc to do 
their options. For some reason gtk doesn't show a message automatically 
when "--help" is in the args, but gstreamer does (maybe a bug in 
pygst?). That is why we have to parse the options before importing gst.

So the proper way to do this is to tell GOption about our desired 
command line options and then GOption will show gstreamer, gtk and 
Jokosher options all in the same --help message. The only problem is 
that python cannot access GOption unless you use pygobject 2.12. 2.12 is 
available in edgy but not anywhere else afaik.

So when everyone is running edgy (or equivalent non-debian based 
distro), I will rewrite the options code to use GOption, and we will be 
able to use all the gtk and gstreamer options alongside Jokosher options.
