-Incubation Disclaimer
-=====================
-
-    Apache OpenOffice is an effort undergoing incubation at The Apache Software Foundation (ASF),
-    sponsored by the name of Apache TLP sponsor. 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.
