+	# 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)

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