# After renaming our organization at GitHub, I had 25 repos I needed to update locally.
# This script finds the current "origin", removes it and replaces it with a new one
# with the organization changed.
#
# Just change OLD_ORG and NEW_ORG below to the old and new organization names and run
# this in each repository.
