### Basic usage

    - variable x has content: {{ x }}
    - expression: {{ x + 1 }}
    - escaped for HTML: {{ x | e }}

### Control structures

    {% for x in range(5) %}
        {% if x % 2 == 0 %}
            {{ x }} is even!
        {% else %}
            {{ x }} is odd!
        {% endif %}
    {% endfor %}

### Whitespace trimming

    these are
    {{ "three" }}
    lines.

    this is conc
    {{- "at" -}}
    enated.

### Special blocks

    {% filter e %}
    {% raw %}
        This is a raw block where {{nothing is evaluated}}
        {% not even this %}
        and <html is escaped> too with "e" filter
    {% endraw %}
    {% endfilter %}

    {% macro myfunc(x) %}
        this is a reusable macro, with arguments: {{x}}
    {% endmacro %}

    {{ myfunc(42) }}
