- * \ingroup DictSet
- * \brief
- * - Consider all the entries of the public dicom dictionary.
- * - Build an hashtable whose keys are the names of the groups
- * (fourth field in each line of dictionary) and whose corresponding
- * values are lists of all the dictionary entries among that
- * group. Note that apparently the Dicom standard doesn't explicitely
- * define a name (as a string) for each group.
- * NO ! Dicom Standard explicitely doesn't define
- * any name, for any group !
- * - A typical usage of this method would be to enable a dynamic
- * configuration of a Dicom file browser: the admin/user can
- * select in the interface which Dicom tags should be displayed.
- * \warning
- * - Dicom *doesn't* define any name for any 'categorie'
- * (the dictionary fourth field was formerly NIH defined
- * -and no longer he is-
- * and will be removed when Dicom provides us a text file
- * with the 'official' Dictionary, that would be more friendly
- * than asking us to perform a line by line check of the dictionary
- * at the beginning of each year to -try to- guess the changes)
- * - Therefore : please NEVER use that fourth field :-(
- * *
- * @return An hashtable: whose keys are the names of the groups and whose
- * corresponding values are lists of all the dictionary entries
- * among that group.
