the PDF file will then be compiled as C (itself!) and executed so that it shows
README.md!
Another PDF file generated is obfuscated C code. Once this is done it will
compile the PDF as if it was C and then run it like:
That procedure looks like:
```sh
./hamano < README.md > hint.pdf
cc -xc hint.pdf -o hint
./hint
```
Another PDF generated is an obfuscated `Hello World!` program (obfuscated inside
the PDF). Once this is done it will compile the PDF as if it was C (itself!). It
will look like:
```sh
echo 'int main(){puts("Hello World!");}' | ./hamano > hello.pdf
cc -Wno-implicit-function-declaration -xc hello.pdf -o hello2
./hello2 | gcc -Wno-implicit-function-declaration -xc - -o ./hello3
./hello3
cc -xc hello.pdf -o hello
./hello | cc -Wno-implicit-function-declaration -xc - -o ./hello2
./hello2
```
although the `CFLAGS` will be what is in the Makefile as it uses the helper
rules `hint.pdf`, `hint`, `hello.pdf` and `hello` to do this.
