# Show all Branches with remote information

# Remove all local branches that are already merged into the remote
#git branch -D $(git branch --merged) # will only work if the current checkout branch is master

# Submodules
# ----------

# Get shallow copies
git clone --recurse-submodules --shallow-submodules

# Avoid shallow copies e.g. for dev work
git clone --recurse-submodules --no-shallow-submodules


# It is possible to automate submodules pushes further with:
# http://stackoverflow.com/questions/14768509/unable-to-checkout-git-submodule-path
git push --recurse-submodules=on-demand
#which also pushes submodules as needed, or starting with 2.7:
git config push.recurseSubmodules on-demand
git push
