rosetter() ( # Notice "(" instead of "{" for this function, see THIS IS A SUBSHELL FUNCTION comments below.

	# ABOUT ROSETTER
	# "rosetter" is a shell/CLI tool to enable (or disable) opening apps using Rosetta on Apple Silicon Macs (as if you had clicked the "Open using Rosetta" checkbox in Finder).
	# To enable opening apps using Rosetta, simply pass "rosetter" the app path(s) and/or bundle identifier(s) as arguments that you would like to enable opening using Rosetta (multiple app paths and/or bundle identifiers can be enabled at once).
	# To disable opening apps using Rosetta, include the "--disable" (or "-d") argument along with the app path(s) and/or bundle identifier(s).
