| 3 | # insert_property.py: For the given install path, library name, and cellname, |
| 4 | # find the Magic layout of the cell, and add the specified property string. |
| 5 | # If the property exists and is the same as specified, then it remains the |
| 6 | # same. If the property exists but has a different value, it is replaced. |
| 7 | # The property is added to the layout in both the mag/ (full) and maglef/ |
| 8 | # (abstract) directories. Option "-maglef" or "-mag" will restrict the |
| 9 | # use to only the view indicated by the option. |
