Lovely people help me with my project. This time, I got a french translation of my slides. They were translated by Marie-Pierre (firstname.lastname@example.org) and I am very thankful for that! She says it is so far just a draft, so if you find any errors, please let her know so she can correct it.
Update: Marie-Pierre asked me to mention that she had great help from people from the project http://libre-et-accessible.org/ with her translation.
