gnome-codec-install doesn't handle --help option

[Alexander Sashnov]

gnome-codec-install doesn't handle --help option neither --usage:

Steps to reproduce:

Try to use 'gnome-codec-install' to setup the codec for playing a video file.

Actual result:

$ gnome-codec-install --usage
invalid commandline '['--usage']'

$ gnome-codec-install --help
invalid commandline '['--help']'

$ gnome-codec-install --help
invalid commandline '['--help']'

I need an example to run it for video file which doesn't play with gstreamer yet like:

$ gnome-codec-install volf.avi
invalid commandline '['volf.avi']'

Expected result:

gnome-codec-install should process at least --help option to give some examples how to run it correctly.
