I just finished removing all the externals. Wasn’t so bad after all. We only had external refs to tablelayout, bullet and soundtouch. If you run into problems when updating your working copy, just do a clean checkout.
Next up: playing around with a temporary git repo so i can figure out how to transfer all our history, branches and tags. I need to do this before i kill the SVN repo on Google Code. May the FSM be with us.
