type t =

type doc_spec =

| DocAbove
| DocNext

Where to print the documentation. For the running example DocAbove * generates * % div N M D R division of N by M gives D with reminder R * pred div i:int, i:int, o:int, o:int. * while DocNext generates * pred div % division of N by M gives D with reminder R * i:int, % N * i:int, % M * o:int, % D * o:int. % R * The latter format it is useful to give longer doc for each argument.
