<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.
