+### Commentary:
+
+## To the best of our knowledge, this code was originally based on the
+## X11 oldXMenu Makefile, which was automatically generated from the
+## X11 oldXMenu Imakefile. There was no explicit copyright information
+## in the Imakefile, therefore we have added the same MIT license as
+## used by the rest of the oldXMenu code.
