val path : Useri.Drop.file -> stringpath f is f's file system path.val prepare : Useri.Drop.file ->
(Useri.Drop.file -> (unit, [ `Msg of string ]) Result.result -> unit) -> unitprepare f k prepares files f for reading, calling k f r whenever
f is ready to be read from (e.g. with Pervasives.open_in).
This is mainly used to hide the upload of the file in
js_of_ocaml's pseudo file system (e.g. on the
`Tsdl backend it will immediately call k). If you need more
control over the upload process you should access the JavaScript file
object directly with Useri_jsoo.Drop.File.to_js.
