Description:
  DO NOT USE THIS CLIENT UNLESS YOU ARE PART OF THE "BUILD" TEAM. 
  This client is generated automatically when GetSource.pl is 
  called as a part of the build process. If client spec
  is changed manually it will not take any effect as the
  client will be deleted and then regenerated during
  build.
