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

# conditions and build environments change, especially when it comes to more

# 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

# Suggestions and corrections regarding Makefiles, winning author information,
