+# An Historical Makefile NOTE:
+#
+# The orig.Makefile, if it exits, is the original Makefile before this IOCCC
+# year directory was reworked so that entries are in separate directories.
+# This also applies to any orig.ansi.mk and orig.common.mk files.
+#
+# Several Makefiles were modified / formed in 2022, and as such it may have
+# elements that are not historically compatible with way entries were built.
+# The orig.Makefile, if it exits, is a copy of the pre-modified Makefile.
+#
+# 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.

+# IOCCC winning entry code may not work on your system.  Even with standards,

+# Corrections on winning author and fixing typos in remarks are VERY WELCOME.

+# An Historical Makefile NOTE:

+# The orig.Makefile, if it exits, is the original Makefile before this IOCCC
+# year directory was reworked so that entries are in separate directories.
+# This also applies to any orig.ansi.mk and orig.common.mk files.
+#
+# Several Makefiles were modified / formed in 2022, and as such it may have
+# elements that are not historically compatible with way entries were built.
+# The orig.Makefile, if it exits, is a copy of the pre-modified Makefile.
+#
+# 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

+# Suggestions and corrections regarding Makefiles, winning author information,

+# 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:

     This program takes no arguments. It emits the base 8 representation
     of prime palindromes (palindromic in base 8, of course).

+# IOCCC winning entry code may not work on your system.  Even with standards,

     Sometimes a core dump is a feature, not a bug!
 
     This is one of the better one-liners we have seen in a while.
     Take some time to figure out what it does before you run it!
