### Include Code Block

Use file inclusion to include text as a code block.

#### File to Be Included

Here's a file containing code to be included:

```hello.rb```:
```markdown
class HelloWorld
   def initialize(name)
      @name = name.capitalize
   end
   def sayHi
      puts "Hello !"
   end
end
```

#### Includer File

Here's a template file that includes it:

```includer.md```:
```markdown
This file includes the code as a code block.

@[:code_block](hello.rb)
```

The treatment token ```:code_block``` specifies that the included text is to be treated as a code block.
