Re: Running OCaml scripts from the command line

[Raphael Proust <raphlalou@xxxxxxxxx>]

There's a plugin called Conque:
http://www.vim.org/scripts/script.php?script_id=2771
http://vim.wikia.com/wiki/Script:2771

You can probably get it with:

:BundleInstall Conque
:ConqueTermVSplit ocaml

I generally use :sh or ! though.
