[NTG-context] French interface - previous message = wrong title

[Garulfo]

Hi,

I try to update and to fill the french content of mult-def.lua.

Currently, I have an updated "mult-def.lua" file. 3 questions :

1/ which commands should be executed in order to make the new local
    interface effective with context

2/ which commands should be executed in order to build a local version
    of setup-fr.pdf

3/ many commands in setup-fr.pdf are not documented in mult-def.lua
    where does the additionnal translations should come from ?

Thanks a lot for your precious help.
