I've meanwhile added leifj's XML output contribution (from 2011, which
never made into Internet2's SVN), Jehan Procaccia's output mode for
easier RRD processing (from 2012; independently published and never
submitted for inclusion), and just now added a JSON output method.

Note that this now requires (and has been tested with) Python 2.6 or
2.7, or Jython 2.7.

I've removed the option `-p` (events per relying party) since `-n` did
the same thing plus numerical sorting of the output, and the speed
differences are negligible, IMO.

The old code still running on Python 2.3 has been tagged as v1.0, for
those seriously stuck on ancient systems.
