+# Legacy systems - actual transformations
+#------------------------------------------------------------------------------------------------------
+#
+# Technical implementation
+# -------------------------
+# Most of the transformations to and from the Danish legacy systems are based on a
+# 7-parameter Helmert transformation, followed by a bivariate polynomial adjustment.
+#
+# The Helmert transformation takes us from the current system (ETRS89) to a system that
+# is sufficiently close to the older systems to allow us to take the final steps using
+# the polynomial ("Horner") way.
+#
+# In most cases, the intermediate system is formally ED50: The parameters produce the
+# least squares optimum route from ETRS89 to ED50. But due to the much more stable scale
+# factor of ETRS89, the ED50 coordinates computed using the Helmert step alone reveals
+# the large tensions in the ED50 net: The Helmert transformed coordinates can be thought
+# of as "ED50 if ED50 had as good a scale factor as ETRS89".
+#
+# To discern, we refer to the Helmert transformed datum as "Technical Datum 32",
+# TD32 - a 2D datum for computational use only. A TD32 coordinate transformed
+# to UTM zone 32, is referred to the "Technical Coordinate System 32, on the
+# TD32 datum", _TC32_TD32.
+#
+# _TC32_TD32 is the step stone from which the bivariate Horner polynomials takes us the
+# final steps to the target system.
+#
+# Naming convention
+# ------------------
+# The transformations to and from Danish legacy systems are named such that to go
+#
+# FROM the current system (i.e. for the time being, GEO_ETRS89),
+# TO system X,
+# use the FORWARD method of the transformation accessed as +init=DK:X
+#
+# and conversely, to go
+#
+# FROM system X
+# TO the current system,
+# use the INVERSE method of the transformation accessed as +init=DK:X
+#
+#
+# Numerical example
+# ------------------
+# For example, one may transform data from GEO_ETRS89 to System 45 Bornholm
+# using the syntax
+#
+# echo 15 55 0 0 | cct +init=DK:S45B
+#
+# which will respond with
+#
+# 42915.059286989766000 37569.188021636372000 -33.327159059233963 0.000000000000000
+#
+# And a forward-inverse roundtrip test can be implemented as:
+#
+# echo 15 55 0 0 | cct +init=DK:S45B | cct -I +init=DK:S45B
+#
+# Which results in this near perfect roundtrip:
+#
+# 14.999999999998458 55.000000000290619 -0.000000000931323 0.000000000000000
+#
+# (the test point 15E, 55N is situated close to the south shore of Bornholm,
+# a few km south of the Pedersker village)
