How to register file extension (MIME types)

[miro]

I've written a simple GTK application and I would like to register some file extension
to be opened with my app.
I've noticed that the MIME subsytem changed a lot in Gnome from version to version.

What is a proper way to acomplish this (I am using FC2) ?

Thanks in advance,
