## ascii-art-output

### Objectives

- You must follow the same [instructions](https://public.01-edu.org/subjects/ascii-art/ascii-art.en) as in the first subject **while** writing the result into a file.

- The file must be named by using the flag `--output=<fileName.txt>`, in which `--output` is the flag and `<fileName.txt>` is the file name.

This project will help you learn about :

- Client utilities.
- The Go file system(**fs**) API.
- Ways to receive data.
- Ways to output data.
- Manipulation of strings.
- Choices of outputs.

### Instructions

- Your project must be written in **Go**.
- The code must respect the [**good practices**](https://public.01-edu.org/subjects/good-practices.en).
- It is recommended that the code presents a **test file**.

### Allowed packages

- Only the [standard go](https://golang.org/pkg/) packages are allowed
