# 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.
