+Apache Tuscany is an effort undergoing incubation at The Apache Software

+Foundation (ASF), sponsored by the Apache Web Services PMC. Incubation is

+required of all newly accepted projects until a further review indicates that

+the infrastructure, communications, and decision making process have stabilized

+in a manner consistent with other successful ASF projects. While incubation

+status is not necessarily a reflection of the completeness or stability of the

+code, it does indicate that the project has yet to be fully endorsed by the ASF.

+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          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
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      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
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+Implementation CRUD Sample
+==========================
+This sample demonstrates how new implementation types are constructed for 
+Apache Tuscany SCA. 
+
+The README in the samples directory (the directory above this) provides 
+general instructions about building and running samples. Take a look there 
+first. 
+
+If you want to try out the CRUD implementation type that this sample provides
+please see the implementation-crud sample that provides the necessary client
+code to bring up an application that uses this implementation extension.
+
+Sample Overview
+---------------
+This sample contains a CRUD implementation type as an example of how to create
+new implementation types. Components using this implementation type always
+expose the same Create, Retrieve, Update and Delete interface. This sample
+uses a singleton ResourceManager to perform the CRUD operations but of course
+a real component would provide a real implementation.

+  pom.xml                      - the Maven build file
+  
+Building The Sample Extension Using Ant
+-----------------------------------------
+With the binary distribution the sample extension can be built using Ant as 
+follows
+
+cd implementation-crud-extension
+ant compile
+
+See the implementation-crud sample to run a sample that uses this
+implementation extension.
+
+Building The Sample Using Maven 
+-------------------------------------------
+With either the binary or source distributions the sample can be built 
+using Maven as follows. 
+
+cd implementation-crud-extension
+mvn
+
+Maven will also test that the sample extension built properly. You should see 
+the following output from the test phase.
