[phpesp-general] translations english-french

[tiah k. <ti...@ho...>]

Hello !

I wish to make translations correctly for French.
so i saw i could modify the "messages.po" file.

this is correct.

but a lot of the interface is still in english.  why aren't all the text 
messages, or titles in the "messages.po" file ?

Do I have to modify the Php files directly to change english to french ? 
what will happen if i install a newer version later ?

thanks

melanie.
