+#
+# Create .COPYRIGHT file at the root of your project (contrib/[PROJECT]/.COPYRIGHT)
+# with the copyright pattern required for your project.
+#
+# echo "Copyright (c) [0-9]\+ Samsung Electronics Co., Ltd. All Rights Reserved" > contrib/[PROJECT]/.COPYRIGHT
+#
+# DISCLAIMER
+#
+# This check works only when your copyright notice is of the following form:
+#
+# /**
+#  * [Copyright notice]
+#  ...
+#  */
+#
+# NOTE
+#
+# The current implementation does not validate YEAR in the copyright notice.
+#
+# TODO Validate YEAR without FALSE POSTIVIES
+#
+# It already turns out that checking the initial commit year introduces
+# FALSE POSITIVES if there are relocated files.
