# this post-receive hook runs globally on my local git machine
# if the knot.conf file exists it reads it to get the remote repo and mirror pushes
# if the file doesn't exist, it doesn't mirror the repo AKA it's private and it stays on my network
#
# USAGE:
# 1) set core.hooksPath to point to where this file is located
#   ex `sudo git --config --system core.hooksPath /home/git/scripts/git-hooks`
# 2) create a knot.conf file in the repo of your choice with the path to your remote 
# 3) push as normal and everything should mirror
