# 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:

Mile is a C code generator. Run without arguments for the help message below:

where [PIN] is an integer in the range of 1..65535
where [PIN] is an integer in the range of 1..65535
```
When run with an encoding PIN (first command line argument), Mile will
read bytes from stdin and generate C code on stdout. Example:
echo "Hello, world!" | ./prog 56789 > encoded.c
```sh
echo "Hello, world!" | ./prog 56789 > encoded.c
```
This generated code will reproduce the same input bytes on stdout when
executed, if it was compiled with the same encoding PIN.
gcc -DPIN=56789 encode.c -o decoded

gcc -DPIN=56789 encode.c -o decoded

The generated code reconstructs all data at compile time by seeding a
random number generator with the given PIN to reproduce the input bytes,
