[Xorp-hackers] Interfacing for runtime config

> Is Python required for anything that is standard in XORP? 

Currently it is needed only for development purpose (though in the
future we may use it for some of the automated test scripts).
E.g., if you change any of the XRL interfaces (xrl/interfaces/*.xif
and xrl/targets/*.tgt) or if you add your own XRL interface,
then python is needed to auto-generate the C++ code.

It is also used to auto-generate the callback C++ code
(libxorp/callback_*.hh), but for all practical purposes you never
want to touch that.
