+# insert_layer.py:  For the given install path, library name, and cellname,
+# find the Magic layout of the cell, and add the specified layer geometry
+# as given by a layer name and a string with four coordinate values.
+# The layer is added to the layout in both the mag/ (full) and maglef/
+# (abstract) directories.  Option "-maglef" or "-mag" will restrict the
+# use to only the view indicated by the option.
