         <H1>Tuscany SCA Native Samples - Python Calculator Sample</H1> 

         <P>This is a very simple sample to show how an SCA composite can wire 
          together two Python components to implement a Calculator service and invoke
          the service via a local client. 
         </P>
         <P>See the <A HREF="../../doc/PythonExtension.html">Python extension</A> 
          documentation for information about building the Tuscany Python extension 
          and using Python in SCA composites.
         </P>
         <P>There are two sub projects in this workspace:</P>
         <UL>
            <LI>sample.calculator<BR/>
                This contains the Python scripts and SCDL artifacts for the SCA Calculator 
                composite implementing the sample Calculator.
            </LI>
            <LI>sample.calculator.client<BR/>
                A sample client which does a local call to the Calculator service.
            </LI>
         </UL>
         <P>Additionally, there is the sample.calculator.app.composite file. This     
            describes the configuration of the SCA Calculator composite deployed to the SCA
            runtime.
