+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or

+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the

+
+The aim is to have the Tuscany runtime embedded in a container with the Tuscany classes hidden
+from user applications and the Spring jar's packaged with the application. That means that the
+Tuscany code has no visibilty of the Spring classes and visa-versa. To implement that the
+implementation-spring module has no dependencies on Spring and the implementation-spring-runtime
+module has no dependencies on Tuscany (other than the sca-api), and reflection is used to call
+methods between the modules.
