I have a git repository, inside there are files/folders, that I want to share across repo.
repo/
     .git/
     html-coding
          css-shared
     js-app
          css-shared
          ttf-shared
     font-files
          ttf-shared
Using Submodules for this task looks like overkill. At times of SVN I've used snv:externals flag, which worked just fine for my purposes.
Subtree is again referencing to external repos, which I don't need at all. Something simple like symbolic links would be acceptable. But I need it cross-platform, since my devs are on Mac, Win and Linux.
