Installation on a new machine:

git clone https://github.com/SimonAB/dotvim.git ~/.vim

Create symlinks:

ln -s ~/dotfiles/vimrc ~/.vimrc
ln -s ~/dotfiles/gvimrc ~/.gvimrc

Switch to the ~/.vim directory, and fetch submodules:

cd ~/.vim
git submodule update --init

To install new plugins:

git submodule add <github url> bundle/<name>

To commit & upload changes to git:

git add .
git commit -m "<description>"
git push

To remove a submodule:

1. Delete the relevant section from the .gitmodules file.
2. Delete the relevant section from .git/config.
3. Run git rm --cached path_to_submodule (no trailing slash).
4. Commit and delete the now untracked submodule files.

Occassionally, the bundles may need updating. To do this:

git submodule foreach git pull origin master
