4. Disclaimer   Copyright 2014 by Cloudsoft Corporation Limited Apache  Brooklyn  is  an  effort  undergoing  incuba3on  at  The  Apache  So0ware   Founda3on  (ASF),  sponsored  by  Chip  Childers.  Incuba3on  is  required  of  all  newly   accepted  projects  un3l  a  further  review  indicates  that  the  infrastructure,   communica3ons,  and  decision  making  process  have  stabilized  in  a  manner   consistent  with  other  successful  ASF  projects.  While  incuba3on  status  is  not   necessarily  a  reflec3on  of  the  completeness  or  stability  of  the  code,  it  does   indicate  that  the  project  has  yet  to  be  fully  endorsed  by  the  ASF.
