# And instead of a plain, boring "1" to end the module source, let us
# celebrate the 14th of July, closely associated with the Bastille:

"-- À la Bastille on l'aime bien Nini Peau-d'chien,
    Elle est si douce et si gentille !
    On l'aime bien...
 -- QUI ÇA ?
 -- Nini Peau-d'chien...
 -- OÙ ÇA ?
 -- À la Basti-i-ille";
