################################################################################

# This work by Landon Curt Noll, Simon Cooper, and Leonid A. Broukhis # Regarding individual entries:
# is licensed under: #
# 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:
