+- 20200713 (Sebastian Oehms, 13 Juli 2020, :trac:`30352`, initial version)
+
+   The tarball has been created from the both download files at the
+   given date:
+
+   ``knotinfo_data_complete.xls``
+   ``linkinfo_data_complete.xlsx``
+
+   exporting them to CSV via LibreOffice.
+
+   The second file has been changed manually deleting one character:
+   a trailing "}" occuring in the homfly_polynomial column of the last
+   link ``L11n459{1,1,1}``.
