	# XXX Python 3 doesn’t allow compiled C files to be included in the scripts 
	# list below. This is because Python 3 distutils tries to decode the file to 
	# ASCII, and fails when powerline-client is a binary.
	#
	# XXX Python 2 fucks up script contents*. Not using it to install scripts 
	# any longer.
	# * Consider the following input:
	#     % alias hex1=$'hexdump -e \'"" 1/1 "%02X\n"\''
	#     % diff <(hex1 ./scripts/powerline) <(hex1 ~/.local/bin/powerline)

	#   (repeated, with diff segment header numbers growing up).

	# FIXME Current solution does not work with `pip install -e`. Still better 
	# then solution that is not working at all.
