Makefile

###################### PlayNet CMD Template Makefile ######################
#
# This Makefile is used to manage the PlayNet command-line template
# All possible tools have to reside under their respective folders in cmd/
# and are being autodetected.
# 'make full' would then process them all while 'make toolname' would only
# handle the specified one(s).
# Edit this file with care, as it is also being used by our CI/CD Pipeline
# For usage information check README.md
#
# Parts of this makefile are based upon github.com/kolide/kit
#
