Add the git flatten command

Clone this and put its bin directory in your path: https://github.com/mbklein/git-tweaks

Flatten

All you have to do to flatten is switch to the branch you want to flatten (master), then flatten and push:

git checkout master
git pull origin master
git submodule update
git flatten -f flat
git push -f origin flat

Get the modules directory out of the way or git will complain of conflicts when you try to switch back to master. Then the reset --hard fixes that.

rm -rf modules
git checkout master
git reset --hard
git submodule update
