3 ===============================================================================
4   This is an example of an XML-RPC client that uses XML-RPC for C/C++
5   (Xmlrpc-c).
6 
7   In particular, it uses the complex lower-level interface that gives you
8   lots of flexibility but requires lots of code.  Also see
9   xmlrpc_sample_add_server, which does the same thing as this program,
10   but with much simpler code because it uses a simpler facility of
11   Xmlrpc-c.
12 
13   This program actually gains nothing from using the more difficult
14   facility.  It is for demonstration purposes.
