SCRIPT-1g-put-initial-files-in-repos

#!/bin/bash

# ----------------------------------------------------------------------
# This script is intended to be "sourced" by other scripts.
#
#   The script doing the "source" must have set the variable:
#     username_files
#   to an array of files from which to obtain usernames
#
# This script:
#   Adds these files to each of the repositories:
#       LICENSE   README.md  .gitignore
#   It obtains those files  from the DATA subfolder, where they are named:
#       DEFAULT-LICENSE   DEFAULT-README.md  DEFAULT-GITIGNORE
#   It then does Add, Commit, and Push on the copied files.
#
# IMPORTANT: If you re-run this script:
#   -- The copied files OVERWRITE the result from the previous run.
#
# Author:  David Mutchler.
