-#
-# Each line is one layer. The specification consists of a layer specification, a colon and arguments.
-# The arguments are named (like "x=...") or in serial. Parameters are separated by comma or blanks.
-# Named arguments are:
-#
-#   zstart   The lower z position of the extruded layer in µm
-#   zstop    The upper z position of the extruded layer in µm
-#   height   The height of the extruded layer in µm
-#
-# 'height', 'zstart' and 'zstop' can be used in any combination. If no value is given for 'zstart',
-# the upper level of the previous layer will be used.
-#
-# If a single unnamed parameter is given, it corresponds to 'height'. Two parameters correspond to
-# 'zstart' and 'zstop'.
-#
-# Examples:
-#   1: 0.5 1.5                    # extrude layer 1/0 from 0.5 to 1.5 vertically
-#   1/0: 0.5 1.5                  # same with explicit datatype
-#   1: zstop=1.5, zstart=0.5      # same with named parameters
-#   1: height=1.0, zstop=1.5      # same with z stop minus height
-#   1: 1.0 zstop=1.5              # same with height as unnamed parameter
-#
-# VARIABLES
-#
-# You can declare variables with:
-#   var name = value
-#
-# You can use variables inside numeric expressions.
-# Example:
-#   var hmetal = 0.48
-#   7/0: 0.5 0.5+hmetal*2        # 2x thick metal
-#
-# You cannot use variables inside layer specifications currently.
-#
-# CONDITIONALS
-#
-# You can enable or disable branches of the table using 'if', 'else', 'elseif' and 'end':
-# Example:
-#   var thick_m1 = true
-#   if thickm1
-#     1: 0.5 1.5
-#   else
-#     1: 0.5 1.2
