	# NOTE: These instructions do not represent a robust, self-troubleshooting install; they
	# are definitely not suitable for dumping to a giant script and running as one. If you
	# use them, they should be run one at a time, with an eye out for errors or problems
	# along the way.
	#
	# The #1 issue you are likely to encounter is with Homebrew or Python packages whose
	# binary components link against system Python. This will result in runtime segfaults,
	# especially in rviz. If you suspect this is occurring, you can attempt to remove and
	# reinstall the offending packages, or go for the nuclear option--- empty your Cellar
	# and site-packages folders and start over with brewed python from the beginning.
