-       Apache Hama is an effort undergoing incubation at The Apache Software Foundation (ASF), 
-      sponsored by the Apache Incubator. 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.
