``includes`` predicatably reads in another file. It's like copy/paste but
MulleScion does the work for you. The contents are parsed just like
any regular template text.

There is a special ``includes verbatim``. It reads the contents of
a file but doesn't parse it.

Here we include the file **set.scion** and have the comments parsed away

#### Example 1
```
{% includes "__demo.scion" %}
```

and the file included verbatim

#### Example 2
```
{% includes verbatim "__demo.scion" %}
```

``includes`` can't be used in multi-line statements.
