Tags: 2.8.3-3
http://bugs.debian.org/580079
* Added README.source. Thanks Manuel Montecelo.
* Removed FindGDAL.cmake file supplied by upstream since it does not
  detect current libgdal1-1.6.0. The script provided by CMake works
  fine.
* Removed openthreads-doc since OpenThreads documentation is shared with
  OpenSceneGraph's, hence this package was empty.
* Now ccache handling is being done automatically by CMake.
* Drop conflict dependencies with previous versions to let them coexist
  with current ones (Closes: #580079 #580081).
