-Apache Guacamole is an effort undergoing incubation at The Apache Software
-Foundation (ASF). 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.
