+# insert_property.py: For the given install path, library name, and cellname,
+# find the Magic layout of the cell, and add the specified property string.
+# If the property exists and is the same as specified, then it remains the
+# same. If the property exists but has a different value, it is replaced.
+# The property 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.
+#
+# e.g.:
+#
+# insert_property.py /home/tim/projects/efabless/tech/SkyWater/EFS8A \
+# s8iom0 s8iom0s8_top_gpio "FIXED_BBOX 0 607 15000 40200"
