# 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

## Judges' comments:
### To build:
```sh
make
```
make
This builds endoh1, echo, hello, and tac.
### To run:
./endoh1 [file.lazy]
```sh
./endoh1 [file.lazy]
```
### Try:
./endoh1 hello.lazy
./hello
echo Hello | ./echo
./tac < endoh1.c
```sh
./endoh1 hello.lazy
./hello
echo Hello | ./echo
./tac < endoh1.c
```
Be patient with the last one.

We liked this entry because it can serve as a standalone program as well as an include file; and, as usual,
because its input data is at least as obfuscated as the program itself.
