Update Git Submodules After Each Merge or Pull

gistfile1.txt

#!/bin/sh
#
# This simple shell script is a Git hook that will automatically
# update all submodules any time you perform a merge or pull.
# This can be useful because you can do things like...
#
#     $ git checkout master && git pull
#
# ...without having to remember to potentially update any
# submodules in the repository.
#
# To use this script save it as `.git/hooks/post-merge` in
# your repository and make the script executable, e.g. via
# `chmod +x .git/hooks/post-merge`.
