I have writted some ppx extension but I have a question,

Is there a proper way to add a start "file" structure.

I have try using the "structure" member of the mapper :

let new_mapper =

Ast_mapper.{
default_mapper with
structure = general_structure
}`

Where general_structure is just a

`my_begining_structure :: List.map (...)` but my begining

structure is repeated into each module. It is logic but I need

to add my own structure only at the begining of my file. In an

other project, I use a mandatory attribute ([@@@active_this_ppx]

for example), but imho, it is not a good approach.

Thanks a lot for your feedback and advices !
