# A simple script to backup an organization's GitHub repositories.
# NOTE: if you have more than 100 repositories, you'll need to step thru the list of repos
# returned by GitHub one page at a time, as described at https://gist.github.com/darktim/5582423
GHBU_BACKUP_DIR=${GHBU_BACKUP_DIR-"github-backups"} # where to place the backup files
GHBU_ORG=${GHBU_ORG-"<CHANGE-ME>"} # the GitHub organization whose repos will be backed up
# (if you're backing up a user's repos instead, this should be your GitHub username)
GHBU_UNAME=${GHBU_UNAME-"<CHANGE-ME>"} # the username of a GitHub account (to use with the GitHub API)
