	@echo can use 0 or more hyphens on key=value
	@echo and they can be ints, floats, or strings:

	@echo you can use key-only flags:
	@echo "*****************************************"
	./example -bunnies stars=300 -dogs=cockapoo
	@echo "*****************************************"
	@echo use the word "no" to negate the flag:
	@echo "*****************************************"
	./example -nobunnies stars=300 -dogs=cockapoo
	@echo "*****************************************"
	@echo or explicitly use "true" or "false" in key=value:

	@echo --- Defaults ---
	@echo this one fills in all the defaults:
