# Note that the path could itself be a python file, or a directory

# Python's compile_all module only works on directories, and requires a max

# Note that the py_byte_compile macro should work for python2 as well
# Which unfortunately makes the definition more complicated than it should be
# The condition should be reversed once /usr/bin/python is python3!
