This might make it easier to use Google Web Fonts in offline environments.

The fonts were always available in a repository format: https://code.google.com/p/googlefontdirectory/

There has been an AUR package for the fonts since 2013-04-27: https://aur.archlinux.org/packages/ttf-google-fonts-git

Git seems like a poor choice for publishing already compressed assets like fonts. Just include the font files you need in your offline applications.
