+"Description: Syntax checking plugin for syntastic.vim
+"Maintainer:  Török Edwin <edwintorok at gmail dot com>
+"License:     This program is free software. It comes without any warranty,

+"
+" By default the camlp4o preprocessor is used to check the syntax of .ml, and .mli files,
+" ocamllex is used to check .mll files and menhir is used to check .mly files.
+" The output is all redirected to /dev/null, nothing is written to the disk.
+"
+" If your source code needs camlp4r then you can define this in your .vimrc:
+"
+"   let g:syntastic_ocaml_camlp4r = 1
+"
+" If you used some syntax extensions, or you want to also typecheck the source
+" code, then you can define this:
+"
+"   let g:syntastic_ocaml_use_ocamlbuild = 1
+"
+" This will run ocamlbuild <name>.inferred.mli, so it will write to your _build
+" directory (and possibly rebuild your myocamlbuild.ml plugin), only enable this
+" if you are ok with that.
+"
+" If you are using syntax extensions / external libraries and have a properly
+" set up _tags (and myocamlbuild.ml file) then it should just work
+" to enable this flag and get syntax / type checks through syntastic.
+"
+" For best results your current directory should be the project root
+" (same situation if you want useful output from :make).
