# This script is meant to be used with the external hooks script for Stash:
# https://marketplace.atlassian.com/plugins/com.ngs.stash.externalhooks.external-hooks
#
# The above plugin is used instead of the "Atlassian Post-Receive 
# Webhooks plugin" because the Atlassian plugin does not support ignoring
# ssl self signed certificates.
# 
# The external hook is useful beyond just this script, thus I prefer it.
