# Quick hack to help you find and deal with old watched repos, forks and owned repos.
#
# It will ask you to confirm once if you want to unwatch a repo.
#
# You can't unwatch your own repos, so they will need to be deleted.
# THIS SCRIPT WILL ASK YOU FOR CONFIRMATION TWICE BEFORE IT DELETES A REPO.
