A description field may use \n to structure the text. For example:

Description: CoHTTP is an OCaml library for creating HTTP clients and
daemons. It has a portable HTTP parser. Optional dependencies
activate functionality:

• Lwt: opam install lwt cohttp
• Lwt and SSL: opam install lwt ssl cohttp
• Async: opam install async cohttp
• Async and SSL: opam install async_ssl cohttp

All newlines are lost when the field is parsed. I do not understand why this was done. I think the original layout should be kept — and maybe at printing one may want to reformat it.

OASISText has Para and BlankLine already so this could be used to partially parse the description (newlines however should be retained).

That is actually a missing part of the documentation.

The "canonical" format of the description field is described here:
https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Description

And is defined in:
https://github.com/ocaml/oasis/blob/master/src/oasis/OASISText.ml

Basically, if you want to keep the itemized list, you just have to put 1 blank at the beginning of the line (if you are usually indented 2 spaces, indent this line 3 spaces).

If you want to keep the separation betwee "functionality:" and the "* Lwt", you have to replace the blank line by a single ".".

In this case the first paragraph will be a Para, then a BlankLine and then itemized list will be translated to Verbatim
list.

I think everything to close the bug is already in place, but we are missing a good documention. I keep the bug open until the documention is written.
