Here's a sample of what's involved. Take this and insert the appropriate French phrase:
'31' => "Remove",
'33' => "Start new topic",
'34' => "Login",
'34a' => "Update Session",
'54' => "Remove",
'55' => "Remove Selected",
'63' => "Moderators",
'66' => "Modify",
'69' => "Email",
'70' => "My Favorites",
'71' => "Add to Favorites",
I'd get things like:
'31' => "Enlever",
'33' => "Commencer le nouveau sujet",
'34' => "Login",
'34a' => "Mettre à jour la Séance",
'54' => "Enlever",
'55' => "Enlever Choisi",
'63' => "Modérateurs",
'66' => "Modifier",
'69' => "E-mail",
'70' => "Mon Favorites",
'71' => "Ajouter à Favorites",
which seems pretty crude to me.
