+Distributed OSGi Calculator Sample
+==================================
+This sample implements a distributed calculator using Distributed OSGi (RFC 119) over SCA.
+
+The README in the samples directory (the directory above this) provides
+general instructions about building and running samples. Take a look there
+first.
+
+On Windows, run
+java -jar ..\..\modules\osgi-3.5.0-v20090520.jar -configuration ..\..\features\configuration -clean -console
+
+On *Unix, run
+java -jar ../../modules/osgi-3.5.0-v20090520.jar -configuration ../../features/configuration -clean -console
+
+You should see the osgi console:
+
+osgi>

+Sample Overview
+---------------
+The application consists of two OSGi bundles:
+ * The calculator bundle: It provides the calculator service. The service is implemented by a java class that
+   consumes other services to perform the “add”, “subtract”, “multiply” and “divide” operations.
+ * The operations bundle: It provides the add/subtract/multiply/divide services.
+   (See ../samples/dosgi-dynamic-calculator-operations)
