Simply the Makefile header.
Refer to the //www.ioccc.org/bugs.md URL (that will eventually exist).
Now using CC BY-SA 4.0 License to how you may share and adapt the
Makefile.
In years < 2001 (with the exception of ferguson2/) that still have
reference to *.hint files they have been changed to README.md with the
following exception: in 1998/dorssel there was a dorssel.hint2. This was
changed to dorssel.hint since the dorssel.hint was changed to README.md
a while back. The references to dorssel.hint2 were changed to without
the 2.
There was an out of date reference in faq.html file to a .hint file as
well that was updated to README.md; the dorssel2.hint in years.html was
changed to the new name.
With that the only files that have to be updated are those that are >=
2001. I still have to check for hint.* however.
The commit 00ae59cd47 had a
mistake that introduces changes to Makefiles for 1996 thru 2020
that should not have been included.
This change reverses these intermediate changes until
the given year's Makefiles are ready.
There is one exception:
$ find . -name '*.hint' -execdir git mv '{}' README.md \;
git statufatal: destination exists, source=1992/albert/albert.hint, destination=1992/albert/README.md
Looking at the two files they differ quite a bit so I've not changed it.
I'll bring this up on GitHub.
We we move 1988-2004 entries from all of a year's winning entries
in a single directory to each winner being in their own sub-directory
under the given year directory.
