The new interface is available since 0.7.93.2, and provides a one-time
iterable tagfile (TagFile is an iterator itself; just like file is).

    for section in tagfile:
        print section[key]

Each 'section' refers to a single objects with its own data. Thus you
can also do things like::

    sections = list(tagfile)

Have fun!
