 * main.cxx
 *
 * PWLib application source file for XMLRPCApp
 *
 * Main program entry point.

 * Copyright 2002 Equivalence
 *
 * $Log: main.cxx,v $
 * Revision 1.7  2003/09/26 13:41:32  rjongbloed
 * Added special test to give more indicative error if try to compile without Expat support.
 *
 * Revision 1.6  2003/04/15 03:00:41  robertj
 * Added array support to XML/RPC
 * Fixed XML/RPC parsing when lots of white space in raw XML, caused by
 *   big fix to base XML parser not returning internal data elements.
 *
 * Revision 1.5  2002/12/04 02:09:17  robertj
 * Changed macro name prefix to PXMLRPC
 *
 * Revision 1.4  2002/12/04 00:16:18  robertj
 * Large enhancement to create automatically encoding and decoding structures
 *   using macros to build a class.
 *
 * Revision 1.3  2002/10/04 05:16:44  craigs
 * Changed for new XMLRPC code
 *
 * Revision 1.2  2002/03/27 01:54:40  craigs
 * Added ability to send random struct as request
 * Added ability to preview request without sending
 *
 * Revision 1.1  2002/03/26 07:05:28  craigs
 * Initial version
