+# remove_label.py:  For the given install path, library name, and cellname,
+# find the Magic layout of the cell, and remove any label equal to the
+# given label text (which may contain glob-syntax wildcards).  Ensure that
+# any port designation for any deleted label is also removed.
+# The label is remove from 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.
+#
+# The cell name may also be wildcarded with glob-style syntax.
