## vim-airlineのインストール

~/.vimrc

```
NeoBundle 'vim-airline/vim-airline'
NeoBundle 'vim-airline/vim-airline-themes'
```

で`NeoBundleInstall`

## fontのインストール

ここが一番悩んだところ。

* https://github.com/powerline/fonts

```
cd path/to/develop
git clone git@github.com:powerline/fonts.git
cd fonts
./install.sh
```

実行結果

```
-> % ./install.sh
Copying fonts...
Resetting font cache, this may take a moment...
Fontconfig error: Cannot load default config file
All Powerline fonts installed to /Users/yoan/Library/Fonts
```

エラーが出たけどフォントは作られていた

```
-> % ls ~/Library/Fonts/
