# ABOUT GIT-SYNC FUNCTIONS
#
# These functions managing syncing and monitoring a large number of
# git repositories, when these repositories are used as part of a
# larger backup and syncronization "service," based on git
# repositories. Configure the operation of this script after reading
# the documentation below.

## Variables
##
################################################################################
# Configure these variables as needed to point to your repositories
#
# $force_commits_repo - contains all repositories that you are ok
# automatically commiting changes (with a
# generic message. This will not remove deleted
# files from your repository.
#
# $force_sync_repo - adds to the `$force_commits_repo` list with all
# repos that you are comfortable performaing a
# `git pull; git push` operation on automatically.
#
# $all_repos - combines the previous two arrays with additional
# repositories that you would like to monitor for changes
# but would like to manually commit and publish changesets.
force_commit_repo=()
force_sync_repo=($force_commit_repo)
