.vim directory with pathogen and plugins as submodules.
Thanks to Pathogen (almost) all you need to install and maintain vim plugins is a git clone command.
By making the $(HOME)/.vim directory a git repo and adding each plugin as a submodule instead of just cloning them, the whole config can be replicated with
git clone --recurse-submodules git@github.com:<your-git-account>/dotvim.git
Please notice that some plugins may have dependencies! For instance, I use Gutentags which needs a ctags executable already available in the target system.
