'''
Live cat of file. Uses mmap to try to be efficient with memory,
though reads a byte at a time, so it burns through CPU by hitting the
python interpreter loop N times. We could add buffering, but that
would just make the code more complex, and who wants that?

stdout gets the default buffering, so consider invoking with
-u flag/PYTHONBUFFERED environment variable if not writing to
a file.

'''
Live tail of a file. Uses mmap to try to be efficient with memory.

Requires fsmonitor: https://github.com/shaurz/fsmonitor

 ...which unfortunately lacks a decent monitor for non-Windows/Linux
systems, so burns up CPU unnecessarily on those platforms. Despite its
reputation, python makes it surprisingly difficult to write clean and
correct code.
