" Last Change:
"              2020 Mar 28 - Improved error format (Thomas Leonard)
"              2017 Nov 26 - Improved error format (Markus Mottl)
"              2013 Aug 27 - Added a new OCaml error format (Markus Mottl)
"
" Marc Weber's comments:
" Setting makeprg doesn't make sense, because there is ocamlc, ocamlopt,
" ocamake and whatnot. So which one to use?
"
" This error format was moved from ftplugin/ocaml.vim to this file,
" because ftplugin is the wrong file to set an error format
" and the error format itself is annoying because it joins many lines in this
" error case:
"
"    Error: The implementation foo.ml does not match the interface foo.cmi:
"    Modules do not match case.
"
" So having it here makes people opt-in
