+/**
+ * \brief DICOM elements and their corresponding values (and
+ * additionaly the corresponding DICOM dictionary entry) of the header
+ * of a DICOM file.
+ *
+ * The typical usage of instances of class File is to classify a set of
+ * dicom files according to header information e.g. to create a file hierarchy
+ * reflecting the Patient/Study/Serie informations, or extracting a given
+ * SerieId. Accessing the content (image[s] or volume[s]) is beyond the
+ * functionality of this class and belongs to gdmcFile.
+ * \note The various entries of the explicit value representation (VR) shall
+ * be managed within a dictionary which is shared by all File
+ * instances.
+ * \note The File::Set*Tag* family members cannot be defined as
+ * protected due to Swig limitations for as Has_a dependency between
+ * File and FileHelper.
