+For people who get this new release :
+
+We consider now that :
+- any dicom related file is a gdcm::Document.
+- a gdcm::Document can be :
+ - a gdcm::File, if it contains pixel data,
+ - a gdcm::DicomDir, if it contains only informations
+ on the files in a given directory
+
+- in a gdcm::Document, there are gdcm::DocEntry, that can be :
+ - gdcm::ContentEntry (any entry that has an actual value,
+ *not* an embedded set of other gdcm::DocEntry)
+ a gdcm::ContentEntry can be :
+ - gdcm::ValEntry (whose value is std::string representable
+ e.g. character values, or integers),
+ - gdcm::BinEntry (whose value is not std::string representable
+ e.g. color palettes, overlays, icons , ...)
+ - gdcm::Sequence (no proper 'value', but a set of gdcm::SQItems,
+ composed of a set of gdc::DocEntry, recursively)
+
+- in a gdcm::DicomDir, we only deal, hierarchically, with :
+ - gdcmPatient
+ - gdcmStudy
+ - gdcmSerie
+ - gdcmImage
