I'm convinced that submodules are the answer, I'm just not sure how to make them work. Assume "sakai" is the superproject and "access" is a submodule, I've done: cd sakai git checkout work git submodule add ../access access And that's cool, but then I do: cd ../access git checkout -b 2-5-x sakai_2-5-x # sakai_2-5-x is an svn import cd ../sakai git checkout -b 2-5-x sakai_2-5-x git submodule add -b 2-5-x ../access access Which gives me an error about access already existing. I'm pretty sure I'm just not thinking about this the way git does, I blame svn for damaging my brain. -- D. Stuart Freeman Georgia Institute of Technology
