	cloudformation-templates: ## Find all Cloudformation Templates e.g. for yamlint, cfnlint, cfnnag, etc...
	@find -E $(CURDIR) \

	# apologies, forgotten the book I got this from... but very useful :O
	# see origin function at https://www.gnu.org/software/make/manual/html_node/Origin-Function.html

	dump-var-origin: ## useful for debugging
	@$(foreach V,$(sort $(.VARIABLES)), \

	# Usage - make dump-var-origin

	## Dump a prettified version of given var, with a column width of 40,
	##e.g.
	##
	## MY_STACK - micks-stack
	## MY_BUCKET - micks-bucket
	## nb: 033 is yellow
	##

	@echo $(1) $(2) \| awk -v width=40 '{printf "\033[33m%-*s\033[0m - %s\n", width, $$1, $$2}'
	endef

	# HELP - will output the help for each task in the Makefile
	# In sorted order.
	# The width of the first column can be determined by the `width` value passed to awk
	#
	# thanks to https://marmelab.com/blog/2016/02/29/auto-documented-makefile.html for the initial version.

	help: ## This help.

	# Allows users to filter their AWS instances, which are running, by Tag Name / Value and see a summarised view.
	#
	# Pre-requisite - Expects one tag to be 'Name'
	#
	# e.g. With 1 Tag Match the Instance tagged with "branch" of "develop"
