Install your Vundle plugins without opening Vim.
It's as easy as running python install.py
.
The script looks for your vimrc files and installs any bundles within them.
I had problems where I would try to install my dotfiles in a docker container build where everything runs headless and vim does not open because there is no screen. After the build finishes Vim is installed but I have to run :BundleInstall every time I launch a container. This script fixes that.
