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