A physical line is a sequence of characters terminated by an end-of-line

sequence. In source files, any of the standard platform line termination

sequences can be used - the Unix form using ASCII LF (linefeed), the Windows

form using the ASCII sequence CR LF (return followed by linefeed), or the old

Macintosh form using the ASCII CR (return) character. All of these forms can be

used equally, regardless of platform.

When embedding Python, source code strings should be passed to Python APIs using

the standard C conventions for newline characters (the ``\n`` character,
