I symlink my ~/.vim directory to this repo. Similarly for ~/.vimrc and ~/.gvimrc.
All addons go in the bundle directory and are managed by Pathogen.
Where possible they are installed as git submodules. For example:
git submodule add https://github.com/airblade/vim-rooter.git vim/bundle/vim-rooter
After a fresh clone of this repository, get the submodules with:
git submodule init
git submodule update
(See Git Submodules: Adding, Using, Removing, Updating for more information.)
If after call pathogen#helptags() you get a warning about a dirty submodule,
add tags to bundle/REPO/.git/info/exclude, where REPO is the repository
giving the warning.
Thanks to John MacFarlane for this tip.
