ADD NEW SUBMODULE
==============
  $ git submodule add http://github.com/scrooloose/nerdtree.git vim/bundle/nerdtree
  $ git submodule init
  $ git commit -m 'add nerd tree plugin as submodule'


UPDATING
======
Git submodules are locked to specific commits in their respective
repositories...in other words, updating the parent repo will not do the same
for that project's submodules.

Running `git submodule update` only makes sure that the submodules are at the
specified cached revision, not the upstream latest. To actually update all of
your submodules to the latest upstream HEAD revisions:

    $ cd ~/.dotfiles/
    $ git submodule foreach git fetch
    $ git sumbodule foreach git merge origin/master
    $ git commit -a -m 'Update all submodules to latest upstream HEAD revision'
    $ git push

REMOTE MACHINE
--------------
    $ cd ~/.dotfiles
    $ git pull
    $ git submodule update


STATUS INFO
========
  $ git submodule status
  $ git ls-files --stage


REMOVE
======
To remove a submodule from your repository, you must edit the obvious
.git/config and .gitmodules files, but also run this command to finish the job:

    $ git rm --cached path/to/submodule
