# A light wrapper for using the <TOOL-NAME> tool via qcr command. 
# This is deliberately light, so that users should never 
# have to update this script once they have it, but will
# always have access to the latest service tool.
#
# It installs (git clones) the <TOOL-NAME> tool if it doesn't
# exist, and then calls the <TOOL-NAME> tool entry point script.
# Information on the <TOOL-NAME> tool can be found at:
#     https://github.com/qcr/<TOOL-NAME>
# 
# For usage on how to use the <TOOL-NAME> tool run: 
#     qcr <TOOL-NAME> -h
