# This script generates modules and tests for geometries. The ZM version of the
# geometries is used as a template.
#
# The file `lib/geometry/point_zm.ex`:
# - `lib/geometry/point_z.ex`
# - `lib/geometry/point_m.ex`
# - `lib/geometry/point.ex`
#
#
# A note for contributors, interested readers or a future me.
#
# There are several ways to create the modules generated by this script. It is
# possible to create all modules at compile-time. In some other modules, this
# approach is in use. Another method could be the use of EEx.
#
# I have chosen the present way to keep developing the "*ZM" modules easier and
# the code readable. As a disadvantage, we get this unelegant script.
# As mentioned above, in some modules, code is created at compile-time. So we
# have two approaches to create code. These approaches should not be mixed in
# one module.
