parameters of the class

[jean beney]

Hello,

I am using a non-standard class designed for LaTeX by a book editor.
One of the differences with the class "book" is that the class has 
different optionnal parameters. But LyX always puts in the LaTeX file:
\documentclass[english,french]{otherbook}
which does not give the result I want.
Is there a way to prevent LyX from writing: [english,french]  ?

I must say that my document  has been declared as being totally in French.
