+Use namespace gdcm:
+  Problem: using enum with name like 'Unknow' on .Net, or LP on cygwin 
+           causes problems.
+  Question: when introducing the namespace, should we remove the gdcm
+            prefix from classes or keep it ?

+Convert the C-like IO to C++ IO:
+  Goal: remove all the C-oriented IO references like FILE*, fread...
+        with the C++ fstream notation. Provide overload of operators
+        << and >> for any gdcm class using file IO.
+  Question: the underlying jpeg libraries (written in C) use the FILE*
+        notation. Is there a way to still use fstream in gdcm, and 
+        build or pass the proper FILE* to jpeg libs ?

+Switch from errno C-style to exceptions:
+  Goal: remove all the C-oriented errno (#include <errno.h>) and switch
+        to C++ exceptions.
+  Note: - only src/gdcmDocument.cxx includes errno.h
+        - when exceptions were first introduced within gdcm, it caused 
+        gdcmPython to be uncompatible within the corresponding version
+        of wxPython (refer to the first lines of
+        Test/ExceptionAndPython/README). Hence we reverted to the old
+        errno mecanisme. Since wxPython seems not to be problem anymore
+        (check it with Test/ExceptionAndPython) we can now move back to C++
+        exceptions.
