# Short version:
# Unlike svn:externals "git submodule" adds a submodule AT A SPECIFIC commit. There's no auto-update!
#

# First update all submodules to HEAD
git submodule foreach git pull origin master

# Commit
git add home/.vim/bundle/* home/.vim/external/* home/.vim/snipmate/*
git commit -m "Updated submodules to the newest version as of `date`"
