[Evolution] Add new language to spell check?

[Ludovic Coumétou <coume mailinglists lubox com>]

Hello,

I was wondering if there is a way to add new language to the spell
checking?
Cos' I mainly write emails in English, but still write quite often
emails in French and in Spanish, and it would be great to have them
spelt checked too :)

Thxs in advance
Ludo
P.S.: I tried to google but without luck
