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

* 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.
