babel question

[jouke hijlkema]

Hello all,

I need to use a class called onera that wants frenchb as the language 
option to pass to babel. How do I do this with LyX. If I pick french for 
a language and export as latex, I get :

\documentclass[french]{onera}

In the tex file. What can I do to get something like

\documentclass[frenchb]{onera}

Thanks in advance

Jouke
