+# IN MEMORIAM: This comment is to remember Scott Rifenbark (scottrif), whom we lost
+# in January, 2020. Scott was the primary technical writer for the Yocto Project for
+# over 9 years. In that time, he contributed many thousands of patches, built this
+# documentation tree, and enabled tens of thousands of developers to succeed with
+# embedded Linux. He ran this Makefile many thousands of times. Godspeed, Dude.
