-#   Transformations to and from the common Nordic referenc frame NKG_ETRF00.
-#   This init-file describes transformations between global reference frames
-#   and NKG_ETRF00 as well as transformations from NKG_ERTF00 to the local
-#   realisations of ETRS89 in each of the countries involved with NKG.
-#
-#   All transformations in this init-file uses the common Nordic frame as a
-#   pivot datum. Exempt from this dogma are transformations with labels
-#   starting with "_". Those transformations are "private" to this file and are
-#   only used as steps in more complicated transformations.
