+* Convert the C-like IO to C++ IO (i.e. remove FILE*, fread...). Some docs
+ are available at
+ http://www.angelfire.com/country/aldev0/cpphowto/cpp_BinaryFileIO.html
+* Remove enable_sequences and ignore_shadow from gdcmDocument().
+* vtk/vtkGdcmHeader.cxx: if speed becomes a concern some changes can
+ be made at the cost of memory consumption (refer to header of
+ vtk/vtkGdcmHeader.cxx)
+* Add a GetVersion() global function.
