===============================================================================
This is the C++ XML-RPC client library for Xmlrpc-c.
Note that unlike most of Xmlprc-c's C++ API, this is _not_ based on the
C client library. This code is independent of the C client library, and
is based directly on the client XML transport libraries (with a little
help from internal C utility libraries).
