Recursively compare two directories to ensure they have the same files and subdirectories

Since a True or False result is all you want, if you have diff installed:

def are_dir_trees_equal(dir1, dir2):
    process = Popen(["diff", "-r", dir1, dir2], stdout=PIPE)
    exit_code = process.wait()
    return not exit_code
