### Include Text As Pre

Use file inclusion to include text as pre-formatted (rather than as a code block).

You might need to do this if you have text to include that has triple-backticks.

#### File to Be Included

Here's a file containing text to be included; the text has triple-backticks.:

```triple_backtick.md```:
```markdown
This file uses triple-backtick to format a ```symbol```, which means that it cannot be included as a code block.
```

#### Includer File

Here's a template file that includes it:

```includer.md```:
```markdown
This file includes the backticked content as pre(formatted).

@[:pre](triple_backtick.md)
```

The treatment token ```:pre``` specifies that the included text is to be treated as pre-formatted.

#### Include Via <code>markdown_helper</code>

```

#### File with Inclusion

Here's the finished file with the included preformatted text:

```included.md```:
```markdown
This file includes the backticked content as pre(formatted).

<pre>
This file uses triple-backtick to format a ```symbol```, which means that it cannot be included as a code block.
</pre>
