I asked on the frws scriptorium, if the community wants to test it on frws ( https://fr.wikisource.org/wiki/Wikisource:Scriptorium/Ao%C3%BBt_2015#Big_green_button ). I'll ask on brws too (but I'll be away).

*You* (dear reader on this mail) can ask *your* community if *you* want this tool or not and how. Nothing has been decided and certainly not in your place.

@Luiz : there is some very good ideas in your mail. If the code works for green, surely it could be adapt easily for yellow.
You have a contention on orthographyon ptws? Can you provide the links? (I'd like to know more as the only convention on frws is to do as the text does)
