1. Copying the Engine Files

[Note] In this example, the engine file is extracted to the examples/bin/ directory to share it with other examples. However, for actual deployment, the engine file is typically copied to the directory where the application’s executable file is located.

For Windows x86 64-bit Extract the engine file to the examples/bin/windows-x86_64 directory
```
7z x tsanpr*-windows-x86_64.7z
```
For Windows x86 32-bit Extract the engine file to the examples/bin/windows-x86 directory
```
7z x tsanpr*-windows-x86.7z
```
For Linux x86 64-bit Extract the engine file to the examples/bin/linux-x86_64 directory
```
tar xvf tsanpr*-linux-x86_64.tar.xz
```
For Linux arm 64-bit Extract the engine file to the examples/bin/linux-aarch64 directory
```
tar xvf tsanpr*-linux-aarch64.tar.xz
```

2. How to Run

Install OCaml and opam

# Linux (Ubuntu/Debian)
sudo apt-get install ocaml opam

# Initialize opam
opam init
eval $(opam env)

Install dependencies

opam install dune ctypes ctypes-foreign

Run anpr
```
cd examples/OCaml/anpr
dune exec anpr
```
