-            at The Apache Software Foundation (ASF), sponsored by the 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
