+- Split out xorriso-tcltk from xorriso: The frontend is advertised
+  as proof-of-concept by upstream. Additionally, we can save a
+  dependency on Tcl/Tk on the main xorriso package.
+- Cleanup using spec-cleaner:
+  + use SPDX3 license string.
+  + Package licence files as license, not doc (boo#1082318).

+%description -n xorriso-tcltk
+xorriso is a program which maps file objects from POSIX compliant filesystems
+into Rock Ridge enhanced ISO 9660 filesystems and allows session-wise
+manipulation of such filesystems. It can load the management information of
+existing ISO images and it writes the session results to optical media or to
+filesystem objects.
+
+This package provides a graphical frontend to xorriso.
