# To add a file, add it in the with_dictionnary list or in the without_dictionnary list depending
#  whether or not the ROOT dictionnary is to be generated.
#  !! Do not forget to fill the LinkDef file !!
#  !! Do not forget to add EXTRA_INTERNAL_LIBRARIES and EXTRA_EXTERNAL_LIBRARIES with the names of the libraries this one relies on !!
