Syntax highlighting for jbuild files used by dune (previously jbuilder).
In the future, I hope to add support for running jbuilder directly from vim.
If you are using pathogen, simply clone this repo into ~/.vim/bundle as follows
$ git clone https://github.com/figitaki/vim-dune ~/.vim/bundle/vim-dune
Currently I have no plans to add support for Neobundle etc. in the future, but PRs are welcome.
