	curlclient.cpp

	Example CURL-based calculator service client in C++

	Service definitions in calc.h (not generated by wsdl2h, but similar)

	$ soapcpp2 -j calc.h
	$ c++ -Iplugin -I. -o curlclient curlclient.cpp stdsoap2.cpp soapC.cpp soapcalcProxy.cpp plugin/curlapi.c -lcurl
	where stdsoap2.cpp is in the 'gsoap' directory, or use libgsoap++:
	$ c++ -Iplugin -I. -o curlclient curlclient.cpp soapC.cpp soapcalcProxy.cpp plugin/curlapi.c -lcurl -lgsoap++
        $ ./webserver 8080 & # see samples/webserver or start ./calcserver 8080 in samples/calc
        $ ./curlclient add 2 3
