+# Regarding individual entries:
+#
+# IOCCC winning entry code may not work on your system.  Even with standards,
+# conditions and build environments change, especially when it comes to more
+# extreme code such you might find in an IOCCC winner.  Moreover, what was
+# allowed and liked in one IOCCC contest may no longer be liked/allowed in
+# later IOCCC years.
+#
+# Corrections on winning author and fixing typos in remarks are VERY WELCOME.
+#
+# GitHub pull requests are welcome:
+#
+# If you have a patch that might make running an entry work in modern Unix-like
+# environments, please create a GitHub pull request for the IOCCC judges to
+# consider.
+#
+# Suggestions and corrections regarding Makefiles, winning author information,
+# fixing typos in remarks, and code patches are welcome via opening a GitHub
+# issue or better yet, by creating a GitHub pull request for the IOCCC judges
+# to consider.  To form a GitHub issue or GitHub pull, please visit:
